Abstract
The utility model relates to an anti-midway-action device of an underground hydraulic tool, which is composed of an inner pipe, a sealing barrel, a communicating body, a sliding sleeve, a sealing ring of the sliding sleeve and a joint and is arranged on an underground tool, such as a hydraulic packer of an oil water well, an anti-jacking slip, a hydraulic releasing, a hydraulic anchor of an oil pipe, a device for anchoring the oil pipe and discharging liquid, etc. The sliding sleeve is used for sealing a communicating hole for pressure transmission inside the underground hydraulic tool and can realize the requirement of a midway pressure test and seal inspection. After the hydraulic tool is lowered into a designed position, the hydraulic tool is lowered into a piston of an oil pump and the sliding sleeve is pushed away so that the communicating hole is communicated and an inner device of a pressure-transmitting tool is operated and lies in a working condition. Because a pressure-transmitting hole is sealed by the sliding sleeve, before the inner device of the hydraulic tool is lowered into the piston of the oil pump, the pressure of the inner device of the hydraulic tool is below external pressure and the inner device of the hydraulic tool can not operate. When a hydraulic tool is lowered into a well, the pressure test and the seal inspection can be operated at any time, the problem of descent midway action can not occur and the success of oil water well operation can be ensured.
Description
One, technical field
The utility model is a kind of oilfield oil well downhole tool, the anti-movement device midway of particularly a kind of underground hydraulic pressure instrument.
Two, background technology
Oil-water well underground hydraulic pressure instrument is provided with anti-movement device midway, as oil water well hydraulic packer, anti-jack slips, hydraulic pressure give up, hydraulic tubing anchor, oil pipe grappling and drainage device etc., these instruments require under instrument behind the precalculated position, boost the pin on the anti-movement device midway cut off or length of spring compressed in ground, instrument could move and make it in running order.But these tool lower portion have all been worn ball-and-seat (oil well pump), the bad control of speed owing to go into the well sometimes, the speed of going into the well is too fast, tubing pressure moment often occurring is much higher than the situation of casing pressure, pin is cut off or length of spring compressed, the problem that appearance is gone into the well and moved midway causes the oil-water well operation unsuccessful, produces economic loss.More than these instruments can't satisfy the requirement of in the process of going into the well the oil pipe pressure testing that is lowered to being tested envelope, as the patent No. 03272577.9 tubing anchor, when also just oil pipe not being suppressed to design attitude down, slips just opens and is anchored on the sleeve pipe, pumping pipe string is anchored and can't continues and play oil pipe, cause the operation of doing over again.
Three, summary of the invention
The purpose of this utility model is the anti-movement device midway of a kind of underground hydraulic pressure instrument of design, makes it too fast in the speed of going into the well, and when envelope was tested in the pressure testing that do not put in place down, the problem that can not occur midway moving can not cause the oil-water well operation unsuccessful.
The purpose of this utility model is achieved in that mainly to be made up of sealing drum, UNICOM's body, sliding sleeve or drainage pin, sealing sleeve is contained on UNICOM's body, sliding sleeve or drainage pin are installed on UNICOM's body, on UNICOM's body linked hole are arranged, and seal linked hole by sliding sleeve or drainage pin.This moment, the hydraulic tool internal pressure was no matter there are many height can not make the action of hydraulic tool interior arrangement, can realize that pressure testing midway tests the requirement of envelope, when under the hydraulic tool behind design attitude, being lowered to the oil well pump piston pushes sliding sleeve open or interrupts the drainage pin and make linked hole UNICOM, pressure imports the tool interior device into to be made it to move back in running order, or drop into object and push sliding sleeve open or interrupt the linked hole UNICOM that the drainage pin makes hydraulic tool inside, pressure imports the tool interior device into to be made it to move back in running order.
The beneficial effects of the utility model are: because pressure transmission hole has been sealed by sliding sleeve or drainage pin, hydraulic tool interior arrangement pressure before being lowered to the oil well pump piston or dropping into object is lower than external pressure, the hydraulic tool interior arrangement can not move, envelope is tested in pressure testing at any time in the process of going into the well, the problem that can not occur going into the well and move is midway guaranteed oil-water well job success.
