Definitions
- the present invention relates to an inflatable bladder tool for the treatment of a well or pipe, for example a casing.
- Such a tool comprises a flexible and elastic annular membrane carried by a mandrel, able to expand radially under the action of an internal pressure developed by a fluid, generally a liquid, which is introduced inside the membrane and is brought to a high pressure.
- a fluid generally a liquid
- the tool can in particular be used as a shutter to temporarily isolate from one another two portions of the well or the pipe.
- the tool having been introduced axially and positioned in the zone separating said portions, it is inflated, so that its membrane is intimately applied against the inner wall of the well or the pipe, by closing it.
- the bladder can also be used as a hydraulic forming tool for lining a portion of the well wall or the pipe.
- the bladder is introduced axially into a radially expandable tube, for example steel, whose outer diameter is slightly smaller than the internal diameter of the portion to be treated.
- a radially expandable tube for example steel
- the tool When the tool is inflated, its wall expands radially and causes the radial expansion of the surrounding tube, forcing the wall thereof to plastically deform (beyond its elastic limit), and to press against the inner wall of the well or the pipe.
- the bladder may be removed, but the tube remains applied against the well wall or the channel and forms an inner liner.
- the inflatable bladder either as a shutter or as a hydroforming liner, it is often necessary to develop a very high pressure inside the bladder in order to inflate it.
- a first technique consists in generating the pressure within the well itself by means of an immersed ad hoc system.
- the pressurized fluid is generated on the surface of the well and applied to the bladder via appropriate transfer means.
- the reference P y denotes the wall of the well, which is vertical, the reference S the surface of the soil in which the well is dug, the reference L the liquid which is present in the lower part of the well, and the reference Hi the height of the well. air above the liquid level.
- Reference 1 designates an inflatable bladder tool, comprising a flexible and elastic, radially expandable, annular membrane supported by upper end 11 and lower end tips 12.
- This tool in the non-inflated state, has been lowered inside the well into a zone to be treated which is immersed in the liquid L at a depth H 2 .
- the tool is surrounded by a liquid whose pressure is proportional to the height of liquid H 2 - Hi.
- the supply of the tool 1 in inflation fluid in this case liquid (water, for example) is provided by a single conduit 2 A from the surface S.
- this power is provided by a pair of non-communicating conduits 2B and 2 'B, in which the fluid flows.
- One of the two channels serves only to control the deflation.
- 1 is also provided by means of a pair of ducts 2C and 2 'C, here communicating;
- One of the channels (2C) communicates with the tool via a pneumatically controlled valve V, driven by the (gaseous) fluid supplied by the other channel (2'C).
- the first solution (Figure IA) has the disadvantage that it is not possible to deflate the tool when the dry column (corresponding to the height Hi) is too large. Indeed, the column of liquid contained in the conduit 2A generates in the tool an excessively high pressure relative to the external pressure, which prohibits deflation.
- the second solution overcomes this difficulty by a circulation of the fluid according to the principle of communicating vessels.
- the time required for purging is excessively long.
- the object of the invention is to provide a control device for inflating and deflating the tool that can be used by a single connection path with the surface, while being simple and robust design, easy of use, and able to work effectively even at great depths, whatever the pressure differential between the inside and outside spaces of the membrane.
- This device is therefore connected to a single duct for supplying pressurized fluid, and is interposed between the outlet of this duct and an integral endpiece of the tool, through which the inlet and the outlet of the fluid take place. ensure inflation and deflation.
- said piston normally occupies, under the action of said spring, a first position, in which it closes the outlet of said supply duct, said duct or purge port then communicating with said duct via chambers of the enclosure;
- said pipe is provided with at least one first non-return valve, calibrated spring, which allows the passage of pressurized fluid from the chamber to the tool when the pressure upstream of the valve exceeds a specific threshold value, and only in this case, and which prohibits the passage of fluid in the opposite direction.
- this channel has at least two branches connected in parallel, one of which is provided with said first non-return valve, and the other is provided with a second anti-return valve.
- -Return the latter allowing the passage of fluid from the tool to the enclosure when the tool side pressure is greater than or equal to the pressure on the speaker side, and only in this case, and which prohibits the passage of fluid in the opposite direction.
- FIG. 2 diagrammatically represents a possible embodiment of the device of the invention, shown at rest, before or after an inflation operation of the tool.
- Figures 3 and 4 are diagrams similar to that of Figure 2 respectively at the beginning and during the operation.
- the scale of the device has been greatly exaggerated in relation to that of the tool 1 to which it is connected.
- This device designated by the reference 3 is mounted at the lower end of the vertical supply duct 2 of the inflation fluid, and interposed between the latter and the upper nozzle 11 of the tool 1.
- the tip 11 is tubular and allows the passage of the liquid inside the membrane 10.
- the other endpiece 12 is a solid piece, acting as a closure cap.
- the two tips 11 and 12 are advantageously guided in axial translation so that they can move closer or apart from each other when the bladder is inflated or, respectively, deflated.
- This device 3 comprises a tubular enclosure 4, mounted in a sealed manner at the end of the duct 2, coaxially with it. In the lower part the enclosure 4 is closed by a flat bottom wall 400.
- a calibrated helical compression spring 55 is disposed in the lower chamber 40 and interposed between the bottom 400 and the piston head 50 so as to push it upwards, in the position illustrated in FIG. 2.
- the piston head 50 comes in abutment against the horizontal annular zone 401 which makes the transition between the lower 40 and central 41 chambers.
- the central chamber 41 communicates with the outside by a horizontal pipe 6 , of short length, arranged radially with respect to the median vertical axis of the chamber 4. This communication could equally well be via one or more orifices pierced in the wall of the chamber 41.
- the upper chamber 42 communicates with the tubular tip 11 of the tool 1 via pipes comprising a first main pipe 30, two parallel pipes 31-32 connected in parallel, and a second main pipe 33.
- the pipe 31 passes through a non-return valve 8 provided with a ball 80 capable of closing the outlet orifice 800.
- the portions of the pipe 31 located upstream and downstream of this valve - if we consider the direction of flow of the fluid from the chamber 42 to the inflatable bladder 1 -, respectively bear the references 31a and 31b.
- the pipe 32 passes through a non-return valve 9 provided with a ball 90 capable of closing the inlet orifice 900 and the portions of the pipe 32 located upstream and downstream of the valve respectively carry references 32a and 32b.
- the ball 80 is pressed down against the seat of the valve 8, closing its passage opening 800, when the fluid pressure in the upstream portion 31a is greater than the fluid pressure in the downstream portion 31b; conversely, it raises and releases the orifice 800 if the fluid pressure in the upstream portion 31a is less than or equal to the fluid pressure in the downstream portion 31b.
- the fluid can then pass through this orifice (from bottom to top in the figures).
- the ball 90 is urged upwards by a spring calibrated so as to be normally applied against the seat of the valve 9, thus closing its passage opening 900.
- a spring calibrated so as to be normally applied against the seat of the valve 9, thus closing its passage opening 900.
- the inflatable tool 1, and the device 3 which it is secured, are lowered into the well to the desired depth.
- the bladder membrane is exposed to an external pressure due to the liquid present in the well which is the same as its internal pressure delivered by the pipes 31 and 33, the valve 8 being consequently necessarily open.
- the inflatable bladder 1 having been positioned opposite its working area, in which the well must be treated, it can proceed to its expansion.
- the valve 8 is closed.
- the inflation of the bladder can then take place.
- the pressure of the fluid brought into the conduit 2 is further increased sufficiently to push the ball 90 against the spring 91 and open the valve 9.
- the fluid can then pass through the tubing 32 and enter via the tubing 33 and the tip tied to the inside of the bladder 1.
- the pressure differential between the inside and the outside of the membrane, shown inflated and referenced 10 'in FIG. 4, is chosen to be sufficient to cause the radial expansion of this membrane and to carry out the desired work, for example a casing. of Wells. It will be noted that during this phase the high pressure developed in the bladder is also found in the downstream portion 31b of the tubular branch 31; this has no importance or impact on the operation of the device because the pressure is the same in the portion 31a, upstream of the valve 8.
- the bladder 1 is deflated. To do this, it suffices to reduce the overpressure in the duct 2 so that this pressure returns to its initial value in FIG. 2.
- the fluid present in the conduit 2 is retained, and the device is immediately ready for a similar new operation.
- the values of the springs 55 and 91 are naturally chosen according to the working conditions, in particular the value of the pressures used and the depth of the zone to be treated, which are themselves a function of the heights H 2 and Hi mentioned above.
- the device may be provided with means for adjusting the force exerted by these springs, so that it can be easily adapted to these conditions.
