Abstract
The utility model belongs to a downhole tool of oil wells, in particular to a retrievable water shutoff pipe column tool, comprising an upper joint (1), a salvaging head (2), a cylinder liner (6), an upper conical body (17), a lower conical body (21), a slips (19), a slips cover (18), a compression ring (16), a packer shaft (15), a sealed packing element (14) and a setting piston (13). A deblocking pawl spring (7) is connected with breaking threads of a lock tube (4), is limited by the salvaging head (2), and fixed through a deblocking shear pin (5), a releasing resistive closing piece (10) that is crimped by a starting piston (8) is mounted in a circular cavity formed by the cylinder liner (6) and the deblocking pawl spring (7), the upper joint (1) is locked on the deblocking pawl spring (7), and the threads of the deblocking pawl spring (7) are connected with the upper conical body (17) and a safety joint claw spring (22). The retrievable water shutoff pipe column tool ensures that the tool can be pulled out of the oil wells, and avoids that the tool is locked and can not be pulled out.
Description
Technical field
The utility model belongs to the oil field downhole tool, instrument on particularly a kind of salvagable water-plugging technology tubing string.
Background technology
At present, it is all unstable that both at home and abroad the water-plugging technology tubing string of adopting two ends in the middle of the envelope is used in the oil field, mainly is that in a single day upper and lower instrument institute interlayer shakes out, and Ka Jing when following instrument is buried the back deblocking by sand often causes overhaul, and time-consuming, influence is produced.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of use reliable, and last instrument lower end is provided with the safety joint device, instrument on the salvagable water-plugging technology tubing string of Ka Jing not during deblocking.
The technical scheme that the utility model technical solution problem adopts is: instrument comprises top connection on the salvagable water-plugging technology tubing string, fishing head, cylinder sleeve, upper cone, lower cone, slips, the slips cover, pressure ring, the packing element axle, cartridge, set piston, be characterized in deblocking pawl spring and lock tube branch break off with the fingers and thumb be threaded spacing and fix by fishing head with the deblocking shear pin, install in the ring cavity that cylinder sleeve and deblocking pawl spring constitute and start the anti-resistance lock dog of giving up of piston crimping, with the top connection interlocking on the deblocking pawl spring, deblocking pawl spring be threaded upper cone and safety joint pawl spring, the safety joint pawl spring is broken off with the fingers and thumb to be threaded with the lower contact branch and is reinforced by the safe shear pin of the spacing usefulness of sliding sleeve.
The beneficial effects of the utility model are: the safety joint pawl spring separated with the lower contact release after instrument was destroyed sliding sleeve on the salvagable water-plugging technology tubing string, and then handled lower tool, guaranteed that instrument proposes outside the well, avoided that instrument is stuck to be carried to come up.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is tool construction figure on the salvagable water-plugging technology tubing string.
Among the figure, the 1-top connection; The 2-fishing head; The 3-snap; The 4-lock tube; 5-deblocking shear pin; The 6-cylinder sleeve; 7-deblocking pawl spring; 8-starts piston; The 9-shear pin of giving up; 10-gives up and resists the resistance lock dog; 11-starts shear pin; 12-sets anti-resistance lock dog; 13-sets piston; The 14-cartridge; 15-packing element axle; The 16-pressure ring; The 17-upper cone; 18-slips cover; The 19-slips; The 20-spring; The 21-lower cone; 22-safety joint pawl spring; The 23-sliding sleeve; 24-safety shear pin; The 25-lower contact;
The specific embodiment
Embodiment, with reference to accompanying drawing 1, the top connection 1 usefulness deblocking shear pin 5 of instrument is connected deblocking pawl spring 7 and fishing head 2 with the shear pin 9 of giving up on the salvagable water-plugging technology tubing string, deblocking pawl spring 7 and lock tube broke off with the fingers and thumb in 4 minutes be threaded spacing and fixing by fishing head 2 with deblocking shear pin 5, cylinder sleeve 6 inboard snap 3 interlocking lock tubes 4, cylinder sleeve 6 is threaded and sets piston 13, set the piston 13 packing element axle 15 that is threaded, install in the ring cavity that cylinder sleeve 6 and deblocking pawl spring 7 constitute start the anti-resistance lock dog 10 of giving up of piston 8 crimping with top connection 1 interlocking on deblocking pawl spring 7.Start the anti-resistance lock dog 12 of setting of piston 8 crimping and will set piston 13 interlockings on deblocking pawl spring 7, start piston 8 and set piston 13 by starting shear pin 11 connections.Cartridge 14 inboards are that the packing element axle of installing 15 articulates pressure ring 16, pressure ring 16 upper cone 17 that is threaded, upper cone 17 articulates slips, cover 18, slips cover 18 articulates slips 19, spring 20, lower cone 21, deblocking pawl spring 7 be threaded lower cone 21 and safety joint pawl spring 22, safety joint pawl spring 22 and lower contact broke off with the fingers and thumb in 25 minutes be threaded fixing by the safe shear pin of sliding sleeve 23 spacing usefulness 24.
Tool work process on the salvagable water-plugging technology tubing string: top connection 1 connects tubing string and goes into the well behind the desired location, connecting line, inject highly pressurised liquid, liquid stream promotion startup piston 8 is cut off to start on shear pin 11 backs and is moved, set anti-resistance lock dog 12 and deblocking pawl spring 7, give up and resist resistance lock dog 10 and top connection 1 release respectively, liquid stream promotes to set piston 13 and moves down and promote packing element axle 15, pressure ring 16, upper cone 17 moves down, promotion slips 19 moves radially and is anchored on the well inwall, setting piston 13 crush seal packing elements 14 makes its diameter increase be close to well inwall upper sealing ring cover space, snap 3 is with moved further interlocking cylinder sleeve 6 and lock tube 4, when instrument up and down finish set after, the upper lifting pipe post reaches when giving up pulling force, the shear pin 9 of giving up is cut off, give up separately, top connection 1 proposes outside the well, packing element axle 15 lower end inner faces and upper cone 17 upper end inner face diebacks during work, cartridge 14 does not recompress, when all after dates of finishing the work are pulled salvagable water-plugging technology tubing string out in well, in well, be lowered to special-purpose fishing tool and grab lock fishing head 2, the upper lifting pipe post is cut off deblocking shear pin 5, deblocking pawl spring 7 and lock tube 4 releases, continue upper lifting pipe post fishing head 2 and articulate lock tube 4, cylinder sleeve 6, packing element axle 15, cartridge 14 is removed the squeezed state deblocking, articulate upper cone 17 successively, slips cover 18, slips 19 is radially regained and is removed grappling, on carry tubing string, salvagable water-plugging technology tubing string is proposed outside the well.Instantly instrument is met the sand card and is carried when motionless, needs to apply downward force to sliding sleeve 23 and cuts off safe shear pin 24 and destroy sliding sleeve 23, and with safety joint pawl spring 22 and lower contact 25 releases, the instrument of will going up earlier proposes, and carries out the secondary sand washing then and salvages down instrument again.
Instrument is applicable to exclusion of interbeded water with the process pipe string of following instrument composition on the salvagable water-plugging technology tubing string.
