Abstract
The utility model provides a rotary device used for downhole operation in an inclined well of a gas field, which is designed to solve the problem that in the inclined well production or in the downhole operation construction, the deflecting segment of a greater diametric downhole tool can not pass through because of the limitation of a well diameter. The utility model is characterized in that the utility model is composed of an upper connector, a ball joint, a press cap, etc. The overall structure is in a spherical surface contact, which can be deflected at arbitrary directions. The utility model has simple structure and easy processing, which solves the problem that the downhole tool in the inclined well operation can not be used.
Description
The utility model provides a kind of inclined shaft transfer that is used for oil-gas field downhole operation.
In the process that the oil gas field inclined shaft is produced or underground work is constructed, because there are the special circumstances of angle buildup interval in inclined shaft, often the flexibility owing to the inclined shaft inclination section is too big with construction tool under the conventional well, cause some instrument can't pass through at inclination section, and the designing requirement that does not reach construction operation, branch as oil-water well is adopted, dividing potential drop, dispensing etc., so just is the reasonable development oil gas field, and the scientific management oil well has brought some problems.Wellfracturing, oil-extracting and water-injecting have to adopt the mode of mixed pressure, mixed water injection.At present still do not understand domestic and international oil gas field and solve the instrument that this type of problem adopts.
The utility model is to provide in a kind of inclined shaft underground work, can make downhole tool waltz through inclination section, and is optionally rotated, simple in structure, the inclined shaft transfer of reliable working performance.
Technical solution of the present utility model is achieved in that the inclined shaft transfer is made of top connection (1), seal (2), (4), pressure cap (3), ball-joint (5).Wherein said top connection (1), ball-joint (5), pressure cap (3) are ball type of contact surface, at top connection (1), pressure cap (3), are useful on the groove of sealing, and described pressure cap (3) has a reaming that is used for making ball-joint (5) deflection guiding in its bottom.
The utility model has only three big parts to form on the whole, simple in structure, be convenient to processing, it can connect with various downhole tools, makes the downhole tool of some Special Categories to pass through smoothly at lower curved section, the repeated use that inclined shaft transfer can be repeatedly, owing to adopt sphere to connect on the structure, thereby can curve by any direction, safe and reliable in the use, the The field proof has good result of use.
Accompanying drawing 1 is a structural representation of the present utility model.
Fig. 2 is a working state schematic representation.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
As shown in Figure 1: inclined shaft underground work instrument, by top connection (1), pressure cap (3) ball-joint (5), O-ring seal (2), (4) form, top connection (1), with pressure cap (3), ball-joint (5) assembling back is owing to adopted spherical contact surface, but arbitrary orientation turns to, have the rubber groove of sealing usefulness at top connection (1) and pressure cap (3), guarantee the high pressure sealing of underground work, operating pressure can reach 50Mpa, because pressure cap (3) bottom has reaming and makes ball-joint (5) can curve arbitrarily with respect to top connection, its angle of bend can be greater than 30 degree, top connection in real work (1) ball-joint (5) connects with tubing string or downhole tool respectively, because of the degree of hole deviation or the overall dimensions difference of downhole tool can connect one or more, in the lower going-into-well when the straight well section, transfer and tubing string are a plumbness, after arriving angle buildup interval, because the action of gravity of tubing string, the top connection of transfer (1) will produce relative torsional bending with ball-joint (5), as shown in Figure 2, its degree of crook size depends on the number of degree of crook He the used transfer of connecting tube post that is used for of the inclined shaft section of making, under the action of gravity of the steering-effecting of transfer and tubing string, the well tool of tubing string and connection thereof will change crooked in company with the variation of hole deviation degree thereupon, will make downhole tool can pass through angle buildup interval smoothly like this.
Claims (2)
1, a kind of transfer that is used for oil field inclined shaft underground work is made up of top connection, pressure cap, ball-joint, it is characterized in that: top connection, pressure cap, ball-joint are ball type of contact surface.
2, transfer according to claim 1 is characterized in that there is a reaming end of pressure cap.
