Abstract
The utility model discloses underground hydraulic control switchgear, which relates to the underground hydraulic control switchgear for oil fields. By adopting the underground hydraulic control switchgear, the problems that the method for lifting a tubular column is complicated to operate, is easy to damage a packer and cannot be used for horizontal wells and inclined shafts, and moreover, the components of an underground motor are easy to damage because of higher underground temperature, and thereby, the application range of the underground hydraulic control switchgear is greatly limited. A shell of the underground hydraulic control switchgear is provided with an oil channel; a ball valve is arranged on the oil channel; the ball valve is provided with a hole; the right side of the shell is provided with a rack pull rod and an incomplete gear; the upper end of the rack pull rod is provided with a disk spring; an overrunning clutch is arranged between the incomplete gear and the ball valve; the left side of the shell is provided with a hydraulic hole; and both ends of the oil channel are communicated with an oil delivery pipe. The underground hydraulic control switchgear disclosed by the utility model has the advantages of convenience and fastness in operation, safety and reliability, accuracy in positioning and the like.
Description
Technical field
The utility model relates to down-hole hydraulic control switch, is specifically related to a kind of oil well pilot production multithread test gauge tap.
Background technology
At present, the pilot production oil stage is an important step before the formal exploitation in oil field.In oil well pilot production test process, need repeatedly open and close oil well, opening or closing of control oil well is accurately successful key element of formation testing.The method of open and close oil well employing at present has two kinds, and a kind of is to control by lifting tubing string, and another kind is to control with downhole electrical motor.Lift the method complicated operation of tubing string, fragile packer, and can not be used for horizontal well and inclined shaft; Adopt the Electric Machine Control mode, because subsurface temperature is higher, at high temperature the components and parts of motor damage easily, thereby have limited its range of application greatly, can not be used for more than well depth two kms, have brought the problem of the many inconvenience of work for the pilot production test job.
The utility model content
The utility model has the method complicated operation that testing arrangement lifts tubing string now in order to solve, fragile packer, and can not be used for horizontal well and inclined shaft; Adopt Electric Machine Control because subsurface temperature is higher, and its components and parts damage easily, thereby have limited the problem of its range of application greatly, and a kind of down-hole hydraulic control derailing switch is provided, the concrete technical scheme that addresses the above problem is as follows:
Hydraulic control derailing switch in down-hole of the present utility model, by disk spring, the tooth bar pull bar, partial gear, one-way clutch, oil pipe, globe valve, housing and oily passage are formed, on housing, be provided with oily passage, globe valve is located on the oily passage, on globe valve, have the hole, be provided with tooth bar pull bar and partial gear on the right side of housing, the upper end of tooth bar pull bar is provided with disk spring, one-way clutch is located between partial gear and the globe valve, globe valve is connected with the rotating shaft end of one-way clutch, the outer shroud of one-way clutch is fixedlyed connected with partial gear, partial gear and the engagement of tooth bar pull bar, having the hydraulic pressure hole on the housing of left side below the shoulder of tooth bar pull bar, the two ends of oily passage are communicated with oil pipe.
Hydraulic control derailing switch in down-hole of the present utility model is to design at oil field production testing operation field demand specially, and this control valve is realized Kai Heguan to the oil pipe passage by apply hydraulic pressure on ground.This down-hole hydraulic control switch not only has plurality of advantages such as simple operation, safe and reliable and accurate positioning.And be widely used in deep-well, horizontal well and inclined shaft, and filled up the industry blank, very extensive in the oil field application prospect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The specific embodiment one: describe present embodiment in conjunction with Fig. 1.Present embodiment is by disk spring 1, tooth bar pull bar 3, partial gear 4, one-way clutch 5, oil pipe 6, globe valve 7, housing 8 and oily passage 9 are formed, on housing 8, be provided with oily passage 9, globe valve 7 is located on the oily passage 9, on globe valve 7, have hole 10, be provided with tooth bar pull bar 3 and partial gear 4 on the right side of housing 8, the upper end of tooth bar pull bar 3 is provided with disk spring 1, one-way clutch 5 is located between partial gear 4 and the globe valve 7, globe valve 7 is connected with the rotating shaft end of one-way clutch 5, the outer shroud of one-way clutch 5 is fixedlyed connected with partial gear 4, partial gear 4 and 3 engagements of tooth bar pull bar, having hydraulic pressure hole 2 on the housing 8 of left side below the shoulder of tooth bar pull bar 3, the two ends of oil passage 9 are communicated with oil pipe 6, and the two ends of housing 8 are connected with oil pipe 6 respectively.
Operating principle:
When needs drive a well, provide pressure by hydraulic pump to the down-hole by the annulus access between sleeve pipe and the oil pipe, pressure is 4.5～6Mpa, the hydraulic pressure hole 2 of hydraulic coupling on housing 8 drives tooth bar pull bar 3 and moves upward, drive partial gear 4 and rotate 90 degree, partial gear 4 is connected as a single entity with the outer shroud of one-way clutch 5, makes the rotating shaft of one-way clutch 5 drive globe valve 7 and also revolves and turn 90 degrees, and oil pipe 6 is opened; When pressure is cancelled, disk spring 1 resets, drive tooth bar pull bar 3 and move downward, partial gear 4 drives one-way clutch 5, and rotating shaft this moment is motionless, oil pipe 6 also is in open mode at this moment, in the time will closing, provide pressure by hydraulic pump to the down-hole by the annulus access between sleeve pipe and the oil pipe again, the hydraulic pressure hole 2 of hydraulic coupling on housing 8 drives tooth bar pull bar 3 again and moves upward, drive partial gear 4 and rotate 90 degree, oil pipe 6 is closed.
