Abstract
The invention relates to a hydraulic pressure tool that proofs the mis-operation while working. It is made up of inner pipe, sealed canister, connection substance, slide bushing, slide bushing sealed circle, and joint. It could be installed on butting proof slips, hydraulic pressure oil pipe anchor, etc. The connection hole sealed by oil slide bushing can transfer pressure. The pressure would be tested at anytime and the mis-operation would not be taken.
Description
One, technical field
The present invention 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 objective of the invention is to design the anti-movement device midway of a kind of underground hydraulic pressure instrument, make it too fast, when envelope is tested in pressure testing when not putting in place down, can not cause the problem of action midway, can not cause the oil-water well operation unsuccessful in the speed of going into the well.
The object of the present invention is achieved like this: seal up the linked hole that the underground hydraulic pressure tool interior is used for pressure transmission with 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 invention has the beneficial effects as follows: 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.
