The oil pipe entered connects, and described top connection 1 lower end is provided with common trapezoidal thread, for connecting with mandrel 2, and described top connection 1 He
Fixing also by anti-rotation pin 3 between mandrel 2, prevent it from mutually rotating, described anti-rotation pin 3 is flush end holding screw.
Described mandrel 2 upper end is provided with common trapezoidal thread, for and top connection 1 connect, in the middle part of described mandrel 2 outer wall by
Up to being arranged with the stretching boss 21 with its integrative-structure and shear groove, described stretching boss 21 is when reclaiming anti-pollution valve
For pulling up elastic claw 5, described shearing groove is used for fixed shear ring 7 and shear pin 8.Described mandrel 2 bottom is arranged
There is common trapezoidal thread, for connecting with lower contact 9.Described mandrel 2 is outside is circumferentially provided with anti-rotation gusset 6, described anti-rotation
Gusset 6 is arranged at stretching boss 21 and shears between groove, is used for rotating elastic claw 5 when reclaiming anti-pollution valve.
Described spacing ring 4 is ring structure, and it is arranged on outside mandrel 2, between top connection 1 and elastic claw 5, and described limit
Ring 4 lower end, position is provided with spacing end face 41, for docking and spacing with anti-pollution valve seating nipple.Described elastic claw 5 is annular solid
Structure, described elastic claw 5 top is arranged between spacing ring 4 and stretching boss 21, and described elastic claw 5 is provided with spiral side's button,
The direction of rotation of described spiral side button is consistent with the direction of rotation of anti-pollution valve seating nipple 10 top spiral side button 101, all can set
Being set to dextrorotation side's button, for docking with anti-pollution valve seating nipple 10 and hold, described elastic claw 5 is relative to the position of anti-rotation gusset 6
Install in respect of axial groove.Described shearing ring 7 is ring structure, is arranged at the shearing grooved position of mandrel 2, described shearing

Work process of the present utility model is as follows:
When entering anti-pollution valve under during completion or well workover, this utility model installs two shear pins 8, on ground even
Connecting this utility model and anti-pollution valve, lower pressure pipe post after being lowered into position in oil well, anti-pollution valve is butted into bottom tubing string
Merit, upper lifting pipe post to certain tonnage, described top connection 1, mandrel 2, shearing ring 7 and lower contact 9 move, shearing ring 7 locks bullet
Property pawl 5, elastic claw 5 is applied to anti-pollution valve power upwards, when on carry slip out of the hand tonnage to design time, shear pin 8 shears, and shears
Ring 7 moves down, mandrel 2 upwards carry to stretching boss 21 contact with elastic claw 5 time, elastic claw 5 is subject to pulling force upwards automatic
Shrink, exit anti-pollution valve, trip out down the feeding tubing string entered, successfully realize entering under anti-pollution valve.
When reclaiming anti-pollution valve during well workover or abandoned well, this utility model is installed 12 shear pins 8, is lowered into
Lower pressure pipe post after Wei, lower contact introduces anti-pollution valve seating nipple 10 smoothly, continues lower pressure pipe post, spiral side's button of elastic claw 5 with
Spiral side's button 101 on anti-pollution valve seating nipple 10 top docks and holds, and the switch step 91 of lower contact simultaneously 9 is by anti-pollution valve
Lining 11 moves down, and circulation canal is opened, and sets up circulation, continues lower pressure pipe post and docks with anti-pollution valve seating nipple 10 to spacing ring 4,
After this presses tonnage to continue to increase at present, tubing string no longer moves, it is judged that has docked and has put in place.Reclaim when using the mode rotating forward tubing string
During anti-pollution valve, rotating forward tubing string, top connection 1 rotates forward together with mandrel 2 and lower contact 9, and the anti-rotation gusset 6 in mandrel 2 drives
Elastic claw 5 rotates forward, it is achieved anti-pollution valve is freed with bottom tubing string and reclaims.Anti-pollution valve is reclaimed when using upper lifting pipe post mode
Time, upper lifting pipe post, described top connection 1, mandrel 2, shearing ring 7 and lower contact 9 move, shearing ring 7 locks elastic claw 5, elastic
Pawl 5 is applied to anti-pollution valve power upwards, when on carry to certain tonnage time, anti-pollution valve shears with bottom tubing string connecting portion,
Realize anti-pollution valve free and reclaim.If rotate forward or on carry still fail reclaim anti-pollution valve, can continue strengthen on carry ton
Position, shear pin 8 is sheared, shearing ring 7 moves down, mandrel 2 upwards carry to stretching boss 21 contact with elastic claw 5 time, bullet
Property pawl 5 automatically shunk by pulling force upwards, exit anti-pollution valve, can meet an urgent need during field operation and slip out of the hand, it is to avoid be anti-
Pollute the problem that when valve reclaims unsuccessfully, tubing string cannot trip out.
Although being described function of the present utility model and work process above in conjunction with accompanying drawing, but this utility model is also
Being not limited to above-mentioned concrete function and work process, above-mentioned detailed description of the invention is only schematically rather than to limit
