Description
Technical field
This utility model relates to a kind of marine salvage equipment, particularly to a kind of oilfield downhole operation fishing device.
Background technology
At present, when existing oilfield downhole operation, when salvaging for sleeve pipe, being usually and reversing tool conveying is arrived design attitude, lift up and transfer drill string, reversing tool drags for and obtains sleeve pipe, lift up drill string and implement back-off to designing requirement tonnage, in smooth back-off situation, trip out instrument and waste and old sleeve pipe.It there is the problem that in the process of reversed stream pipe, there will be the skidding of anchor tooth, grappling does not live sleeve pipe phenomenon, affects normal reversed stream, it could even be possible to there is the great work accident poured out together by the sleeve pipe dragged for below lance, even cause disused well, and then produce into huge economic loss.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, it is provided that a kind of oilfield downhole operation fishing device, its simple in construction, reliable operation, improves salvaging efficiency.
Its technical scheme is: include top connection, cylinder, inner core, spring, slips, swivel joint, guide shoe, rotation bar, the top of cylinder is threaded connection top connection, the inside of described cylinder is provided with inner core, the outer wall of inner core is provided with spring, the bottom of described inner core connects slips, and the bottom of cylinder connects guide shoe, and the top of described cylinder is provided with swivel joint, swivel joint connects inner core by rotating bar, and the bottom of guide shoe is provided with tapered guide head.
Above-mentioned swivel joint includes drawing together inner ring, outer ring and ball, and inner ring is connected in the arc groove of outer ring, and the gap location of the arc groove of inner ring lateral wall and the arc groove of medial wall, outer ring is provided with ball, and ball is connected in the inner chamber of ball fixture.Swivel joint prevents the rotation of cylinder, causes the damage to sleeve pipe, improves the protected effect to sleeve pipe.
The beneficial effects of the utility model are: its simple in construction, reliable operation, drive rotation bar to rotate by hydraulic power unit and realize guide shoe by junk introducing, device is made to go into the well smoothly, avoid the abrasion between sleeve pipe, improve job success ratio, reduce operating cost.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model；
Accompanying drawing 2 is the structural representation of swivel joint；
In upper figure: top connection 1, cylinder 2, inner core 3, spring 4, slips 5, swivel joint 6, guide shoe 7, rotation bar 8；Inner ring 6.1, outer ring 6.2, ball 6.3, ball fixture 6.4.
Detailed description of the invention
In conjunction with accompanying drawing 1-2, the utility model will be further described:
This utility model includes top connection 1, cylinder 2, inner core 3, spring 4, slips 5, swivel joint 6, guide shoe 7, rotates bar 8, the top of cylinder 2 is threaded connection top connection 1, the inside of described cylinder 2 is provided with inner core 3, the outer wall of inner core 3 is provided with spring 4, the bottom of described inner core 3 connects slips 5, and the bottom of cylinder 2 connects guide shoe 7, and the top of described cylinder 2 is provided with swivel joint 6, swivel joint 6 connects inner core 3 by rotating bar 8, and the bottom of guide shoe 7 is provided with tapered guide head.
Wherein, swivel joint 6 includes drawing together inner ring 6.1, outer ring 6.2 and ball 6.3; inner ring 6.1 is connected in the arc groove of outer ring 6.2; the gap location of the arc groove of inner ring 6.1 lateral wall and the arc groove of medial wall, outer ring 6.2 is provided with ball 6.3; ball 6.3 is connected in the inner chamber of ball fixture 6.4; swivel joint prevents the rotation of cylinder 2, causes the damage to sleeve pipe, improves the protected effect to sleeve pipe.
Operation principle:
Its simple in construction; reliable operation; drive rotation bar to rotate by hydraulic power unit and realize guide shoe by junk introducing; making device go into the well smoothly, swivel joint prevents the rotation of cylinder 2, causes the damage to sleeve pipe; improve the protected effect to sleeve pipe; avoid the abrasion between sleeve pipe, improve job success ratio, reduce operating cost.
The above, be only preferred embodiment of the present utility model, and this utility model is all revised possibly also with the technical scheme of above-mentioned elaboration or is revised as equivalent technical scheme by any those of ordinary skill in the art.Therefore, any simple modification carried out according to the technical solution of the utility model or substitute equivalents, belong to the greatest extent the scope that this utility model claims.
