Description
Technical field
It the utility model is related in oil well operation technical field, more particularly to a kind of oil well repairing operation and pull off formula jarring
Release device.
Background technology
It is situated between during underground work, is frequently encountered the situation that down-hole string or instrument are stuck, tubing string or instrument quilt
The position of card we be referred to as " stuck point ".Because production needs, need to come out from well treatment by the tubing string of card or instrument, commonly use
Method be by tripping in fishing string and instrument, drag for by the tubing string or instrument of card, with ground installation to fishing string one
Larger upper lifting power, then quick decentralization, to " stuck point " one above carry and under hit alternate power, the process is referred to as " living
Dynamic unfreezing ".
Because Petroleum Production well is not completely vertical, but certain angle be present with vertical direction, the phenomenon claims
Be hole deviation, due to the presence of hole deviation, the tubing string in well will produce frictional force with the borehole wall, so as to influence fishing string to stuck point
Active force.During activity unfreezing, due to the elongation of tubing string and the presence of hole deviation, in decentralization, downwards to the big portion of impulse force of stuck point
Divide and be consumed in the reduction of tubing string and the friction of tubing string and the borehole wall, impulsive force discharges in this process, makes the power at stuck point can not
Mutation is realized, i.e., can not realize the jarring to stuck point, substantially reduce activity unfreezing effect.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
Reference picture 1-2, formula bumper stuck releasing device, including 1, second set of the first sleeve are pulled off in a kind of oil well repairing operation
Cylinder 2, top connection 3, lower contact 4, mandrel 5, the first locating part 6 and the second locating part 7, the side of the first sleeve 1 offer annular
First pull off groove 8, the both ends of the first sleeve 1 are separately installed with top connection 3 and lower contact 4, and the both ends inside the first sleeve 1 are equal
The first groove of annular is offered, the inside of the first sleeve 1 is socketed with second sleeve 2, and the side of second sleeve 2 offers annular
Second pull off groove 9, fixed cover is connected to the first locating parts 6 of two groups of annulars in second sleeve 2, and two group of first locating part 6 is distinguished
The both sides for pulling off groove 9 positioned at second, two group of first locating part 6 are located on the first sleeve 1 in first groove at both ends respectively, and second
The inside of sleeve 2 is socketed with mandrel 5, and the equal fixed cover in both ends of mandrel 5 is connected to the second locating part 7 of annular, the second locating part 7
