Description

 PRODUCT RESTORATION METHOD AND DEVICE

 HORIZONTAL WELL AND INFLUENCE ON THE LAYER

FIELD OF THE INVENTION The group of inventions relates to the oil and gas industry for cleaning the bottom-hole zone of a horizontal well and mounted filters, as well as for intensifying oil production. The method includes the delivery and placement in the horizontal wellbore of an ultrasonic emitter, the operation of which in various modes and at different frequencies allows to optimize its operation. State of the art

In the oil and gas industry in recent years, drilling with horizontal completion has increased significantly. Their drilling, development and operation are significantly different from the technology of hydrocarbon production through vertical wells, in this regard, the methods used for stimulation in vertical wells are in most cases not suitable for horizontal wells.

There are many known methods of chemical treatment of a horizontal well (Patents RU 2531985 from 09.17.2013, RU 2599155 from 09.24.2015, RU 2520989 from 03.13.2013, RU 2288356 from 11.22.2005, RU 2471978 from 1.07.201 1 g ., RU 2287680 dated 08/10/2004, RU 2554962 dated 05/08/2014, RU 2235865 dated 09/29/2003, RU 2599156 dated 09.24.2015, 2144616 dated 06.22.1998, RU 2325517 dated 05.29.2007). All these methods are feasible either using a large number of chemicals, or using a large number of additional equipment. All this leads to large financial and labor costs, increased costs of time and materials. The environmental hazard of these methods is also important. Methods of thermo-chemical action on horizontal wells are also known from the prior art (Patents RU 2527434 from 08.27.2014, RU 2004124482 from 01.27.2006, RU 2287680 from 08.10.2004). These methods have the same drawbacks as the previous ones.

The prior art hydrodynamic methods for processing horizontal wells (RU 94033081 from 09/09/1994, RU 2074305 from 09/09/1994). These methods are also characterized by cumbersome equipment and high labor and time costs.

The closest in technical essence and the achieved result is the method and device (Patent RU 2600249 from 01.24.2014). The method involves the impact on oil reservoirs and the bottomhole zone of a horizontal well by lowering into the well a device for generating pulses with the possibility of explosive plasma formation. For this, a two-module electro-hydraulic device is used. The first module contains a capacitor charge block, and the second block contains a capacitor block, an emitter and an active substance supply unit connected to the control module and equipment at the wellhead with the possibility of transmitting charge and discharge data of storage capacitors in order to initiate successive elastic vibrations at given horizontal end points . The device generates periodic directed short pulses due to the explosion of a calibrated wire, leading to the formation of a plasma and directed radially shock wave of high pressure.

The device is launched on a coiled tubing type flexible pipe.

These method and device have several disadvantages. The main one is the inability to distribute the shock wave uniformly in the radial direction. The wave is on the path of least resistance, i.e. the main energy will go through the most permeable pore channels. If there is a filter in a horizontal well, an uneven distribution of energy will also occur along the radius of the well. Involvement of previously missed weakly drained stagnant zones into development is also random.

The essence of the group of inventions.

From the theory of oilfield development, we know that many factors influence well productivity. A number of them has a mechanical origin, such as: the formation of a clay crust on the walls of the well during drilling; penetration into the formation of drilling fluid; penetration into the reservoir of mud filtration; penetration into the reservoir of filtration of cementitious compositions; mechanical impurities in the filling fluid during completion of the well or its repair, which clog perforations; penetration into the reservoir of filling fluid; clogging the pores of the formation with clays contained in the formation rock; deposition of asphalt-resinous-paraffin deposits in the reservoir and the bottomhole zone, clogging of perforation holes with them; salt deposits in the reservoir and bottomhole zone; the formation of various emulsions in the reservoir; injection of various emulsions into the reservoir; injection of various solvents with mechanical impurities; plugging of the pores of the formation and the bottomhole zone with reaction products from various types of well and formation treatments (chemical, thermal, etc.) The above factors significantly reduce the permeability of the formation and, as a result, the productivity of the well decreases, sometimes until the flow stops.

The objective of the proposed technical solution is to clean the bottom-hole zone of the formation from the listed types of contamination, create cracks and microcracks in the radial direction, tens of meters long, and involve oil in the development of stagnant zones. This will not only restore the flow rate of the well, but also significantly increase it compared to the original.

Disclosure of invention

 These results are achieved by applying a method of stimulating a formation, which includes delivering a complex stimulation device to the horizontal end of a well. The complex device includes a radial acoustic emitter, a block of geophysical instruments and an electro-hydraulic emitter with a plasma spark gap, which are interconnected by typical geophysical adapters.

A radial borehole acoustic emitter is structurally designed so that it can be made up to 50 meters long.

The design of the downhole acoustic device is illustrated by the illustration (Figure 2), which shows a longitudinal section of the device.

The downhole acoustic emitter includes an upper head providing connection with a contact device for a cable lug, a lower head connected to each other in a single structure, metal sealed cases (30), in which piezoelectric transducers (31) are placed in pairs with an offset of 90 ° from each other. Piezoelectric transducers (31) consist of longitudinally polarized, electrically connected piezoceramic washers (5 pcs. In each piezoelectric transducer). Piezoelectric transducers (31) are fastened together by tightening screws (32) (4 pcs.). Between piezoelectric transducers rubber-metal gaskets are installed (33). For reliable fixation of the piezoelectric transducers (31), sleeves (35) are installed in the housing (30), to which the coupling screws (32) are attached.

This device provides independent operation of each piezoelectric transducer (31) located in the housing (30). This is due to the mutual arrangement of the piezoelectric transducers (31), as well as the presence of rubber-metal gaskets (33). Such a constructive implementation allows to increase the selectivity of acoustic impact on the well, bottomhole zone, formation.

The upper and lower cases (30) are interconnected by metal cables (37) (4 pcs.) And the part (36) formed by rubber-plastic filling of the junction of the two cases (30) with a small gap. This design provides flexibility that allows you to freely pass the curved sections of the well. In addition, the connection of the housings (30) using metal cables and the part (36) provides an increase in the lateral compliance of the housings (30), which increases the radiation efficiency in the radial direction. Such a device also has a longer service life, since the flexible connection of the housings (30) eliminates its destruction under the action of high pressure in the well and makes the device less fragile. The casing (30) is secured and sealed by compressing and radially expanding the rubber gasket (34) with compression nuts (38), which are attached to the bushings (35) (screwed or welded). The nuts (38) have protruding parts, which ensure the attachment of metal cables to them (37). Of these, a loop (closed connection) is performed, which simultaneously slips on the protruding parts of the nuts (38) located in two adjacent housings 30.

Piezoceramic washers are fastened together with metal washers, a screw (41) and a nut (42). Piezoceramic washers are prestressed using a screw (41) and a nut (42). Using a given voltage, it is possible to adjust the resonance frequency and the impedance value of each piezoelectric transducer (31) to the required values at the time of assembly. Additional sealing and fastening of the housings (30) is provided by rubber-plastic pouring (36) at the junction of two adjacent buildings (30). Power is supplied to the piezoelectric transducers via wires (39), which pass through the channel for electric wires. Piezoelectric transducers (31) are connected to wires (39) in a parallel circuit. Wires (39) between two adjacent housings (30) are connected using standard geophysical connecting nodes ("five-copecks") (40) and filled with rubber-plastic. To prevent the rubber-plastic from getting inside the housing (30) into the cylindrical holes of the bushings (35), rubber plugs (43) are installed. The external and internal surface of the housing (30) may have grooves in the form of a groove that are milled along the length of the housing (30) (not shown in the figure). The presence of such recesses provides a certain directivity of acoustic radiation, and also leads to lateral compliance of the body (30). Such a structural embodiment allows to obtain radiation in the radial direction. The electronics unit is hermetically connected to the housing (30) (not shown in the figure), designed to generate a signal with the working frequency of the piezoelectric transducers (31) and to automatically adjust the parameters of the piezoelectric transducers (31) (frequency, voltage, phase shift) directly during operation depending on the processing results in the electronics block of signals taken from the built-in sensors for monitoring the operation of piezoelectric transducers (31).

The emitter operates in two modes: continuous and pulsed. In constant mode, the emitter operates at frequencies close to 20,000 Hz. At these frequencies, the effects of ultrasound act: - breaking of intermolecular bonds (the destruction of stable bonds at the interface between pores and fluid);

- capillary effect; destruction of colmatant, asphalt-resin-paraffin and mineral deposits; - a change in the rheology of oil, the approximation of its properties to the properties of Newtonian fluid.

Due to these effects, the pores of the bottom-hole formation zone are cleaned within a radius of about 3 meters and perforations.

In pulsed mode, the emitter operates at frequencies of about 100 Hz. In this mode, the wavelength is several tens of meters, depending on the propagation medium (for example, in water is 15 meters). Its feature is a slight attenuation at large distances (more than 1000 meters). At an impulse, high inrush currents (up to 10 A) work and powerful energy emissions occur (about 20 kJ per hour), which allows the sound wave to propagate to a distance of up to 1000 meters with little loss of efficiency. This allows you to affect the entire supply area of the well and to attract stagnant zones.

The design of the ultrasonic emitter is made in such a way that allows additional electrical conductors to pass through it. That allows you to connect to it a block of geophysical instruments (also made through passage). The block of geophysical instruments includes MLM Group (gamma-ray logging and magnetic locator of couplings), temperature and pressure sensors, a moisture meter and a flow meter.

GK MLM allows you to bind the device to the depth of the well and the position of the device in the horizontal well, for accurate processing. Other instruments allow real-time monitoring of well operation and emitter operation. This allows you to perform three tasks:

one . Monitoring the operation of the well and the emitter.

 2. The ability to adjust the operation of the emitter depending on the parameters obtained.

 3. Confirmation of the effectiveness of the proposed complex devices.

After the instrument cluster, an electro-hydraulic radiator with a plasma spark gap is connected (Fig. 3). The emitter has design features that distinguish it from the analogues used. Structurally, an electro-hydraulic complex with a plasma spark gap

(EGKPR) consists of two main parts: a ground-based power and control unit and a borehole electro-hydraulic emitter.

On the surface, a complex device, through a hose cable, is connected to a multifunctional control and control panel (MFPKU). MFPKU consists of blocks: a power supply and control unit for an acoustic emitter, a log recorder, a power supply and control unit for an electro-hydraulic emitter.

All of them are connected through a hose-cable (inside of which electric conductors pass) with devices delivered to a horizontal well and perform power and control functions. The borehole electro-hydraulic emitter has a modular design

(Fig. 4), consisting of a stabilization unit, a block of capacitors and a plasma spark gap. It has a length of not more than 3 meters and a diameter of not more than 44 mm, which ensures free passage of the device through all existing tubing.

The stabilization unit includes a step-up decoupling transformer, which also powers the plasma ignition unit in the discharge gap. Capacitors are used in the capacitor block: one pin is a coaxial pin, the second is a cylindrical body - you get a parallel connection to the battery by simply attaching the pins. This design takes up a minimum of space and allows the use of small components. The modularity of the design allows you to increase the power of the downhole electro-hydraulic emitter, due to the use of additional blocks of capacitors, in the required range, for example, from 0.5 to 3 kJ. Modularity is ensured through the use of a special rubber-plastic connection reinforced with cables. A special role in the invention is played by the design of the plasma arrester. Unlike the prototype, it has not an electric, but a mechanical drive. It is made in the form of a block, easily disassembled design, which allows you to easily replace any parts, as well as install a new coil with wire, which is especially important in the field. The arrester housing (2) is screwed onto the connection sleeve (1) and secured with a screw. In the lower part, a support sleeve made of fiberglass (9) is screwed to the arrester housing, to which all other elements are attached. In the middle part of the sleeve, a cylinder (7) is screwed in, in which a piston (8) with a rod and a spring is installed. Holes (18) are made in the piston to equalize the pressure of the over-piston space with the pressure in the well. A wire feed mechanism (6) is attached to the upper part of the piston, which is also a limiter that holds the piston in a predetermined position. The feed mechanism is a lever with a support platform (14) and a link with a spring (13). On the supporting platform and the backstage from the side facing the wire (12), special directional notches have been made, allowing the feed mechanism to move upward without affecting the wire, and when moving downward, providing engagement with the wire.

Four rods (5) are attached to the cylinder (7), which are the basis for the attachment unit (4) of the coil (3). The rods also ensure that the cylinder is kept from knocking out of the sleeve (9) when exposed to the piston (8), due to the support on the connecting sleeve (1).

In the supporting sleeve (9), 2 holes are made for attaching the electrodes (17, 19). The electrodes are insulated (23), eliminating the flow of current. Only areas providing a plasma discharge are open. The power wire is attached to the positive electrode (20) using the terminal (22) and a special screw (21). A power wire is also attached to the negative electrode (19), but a special axial hole is made in the electrode for the passage of wire (12). To seal the hole, a special sealing insert (15) is used.

From below, a guide cone (11) is fastened to the support sleeve using racks (10). It provides free movement of the SEGP along the tubing and at the same time, together with the racks, protects the electrodes from mechanical stress.

The operation of the electro-hydraulic complex is as follows. The ground power supply unit is connected to an alternating current network with a voltage of 220 V, converts it to direct current and transfers it via a geophysical cable to the stabilization unit and the capacitor unit. Electrical energy is accumulated in the capacitors and when they are filled, a plasma discharge occurs through the electrodes (17, 18) connected by a wire (12), which is previously set to the desired position. As a result of a plasma discharge, an electrohydraulic shock occurs, affecting the oil reservoir and its bottomhole zone, which helps to stimulate enhanced oil recovery and intensify oil production.

The shock wave also acts on the piston (8), which rises, compresses the spring and moves the wire feed mechanism (6). The surfaces of the support platform (14) and the wings (13) easily slide up the wire (12). When the spring is straightened, the feed mechanism goes down and due to special notches on the support platform and the link and the link spring, which provides its pressing, pull the wire down through the negative electrode until it contacts the positive electrode. Then the whole cycle is repeated.

In this way:

Firstly, the emitter has a modular design, which allows, due to the different number of modules, to vary the emitted energy in the range from 0.5 to 3 kJ (depending on the geological characteristics of the well and its design). Secondly, capacitors are used in the emitter to minimize the occupied volume. As a result, the length of the emitter is 2 times less than analogues, and the diameter is reduced to 52 millimeters.

Thirdly, unlike analogs, a mechanical wire-drawing device is used, made in the form of a quick-detachable unit, which allows changing the wire in the field and avoiding complex electrical and electronic circuits.

The complex device is delivered to the horizontal section of the well with the help of a hose-cable, which is wound on a special drum and driven by a special installation for winding-unwinding and a special conveyor for its delivery to the well. This hose cable hoist is commercially available from many factories.

On the surface, a complex device, through a hose cable, is connected to a multifunctional control and control panel (MFPKU). MFPKU consists of blocks: a power supply and control unit for an acoustic emitter, a log recorder, a power supply and control unit for an electro-hydraulic emitter. All of them are connected through a hose-cable (inside of which electric conductors pass) with devices delivered to a horizontal well and perform power and control functions.

The implementation of the method is as follows: On a umbilical, using a special lift, a complex device consisting of an electro-hydraulic radiator with plasma discharger, geophysics unit and acoustic emitter. Pushing the complex device to the end of the horizontal section, through the block of geophysics, the instruments are attached and the parameters of the well are taken before treatment. Within two hours (the time depends on the parameters of the well and calculated in laboratory conditions), the near and far zones are processed in constant (work for an hour at a constant frequency of 20 kHz) and pulse (work of 10 pulses per second at a frequency of 100 Hz for an hour) modes, which leads to the restoration of the permeability of the near zone and to the movement of the reservoir fluid in the far and stagnant zones.

Then the electro-hydraulic radiator is turned on and the plasma is processed by the plasma of the cleaned area (up to 50 meters). A shock wave of high pressure with an energy of up to 3 kJ (the energy value depends on the number of capacitors in the modules and is calculated mathematically) is evenly distributed in the radial direction, creating cracks in the near zone and pushing oil out of stagnant zones. Then the block of geophysics is connected and the current parameters are removed, allowing, if necessary, to adjust the operation of the equipment. Then, the processes are repeated until the horizontal section of the well passes completely.

For efficient and safe movement of the device complex along the horizontal section, it is equipped with centralizers and a pressure sensor.
