Abstract
The utility model discloses a lifting-putting fishing tool capable of withdrawing comprising a upper connector, a center bar, a spring, a cover, a track pin, a swivel, a fluke and a dragging bar, inwhich one end of the center bar connects with the dragging bar, and the other end connects with the upper connector; the spring, the cover, the track pin, the swivel and the fluke are set in turn from top to bottom of the dragging bar. The utility model has the advantages of a scalable fluke, high fishing efficiency and stability, is widely used in the petroleum mining underground operation, especially the fishing operation of the horizontal well.
Description
One, technical field
The utility model relates to power tool under the petroleum horizontal well, particularly a kind of lifting-putting fishing tool capable of withdrawing.
Two, background technology
The oil exploitation horizontal well is more and more at present, but horizontal well well workover kit is gone back imperfection, continues to use the straight well instrument substantially.Because the particularity of horizontal well wellbore trajectory, so adopt conventional downhole tool just to exist many being inconvenient to reach very big risk to the horizontal well well workover, the particularly unfreezing fishing operation of down-hole string, under the unsuccessful situation of unfreezing, often cause down-hole accident complicated, influence the process of underground work.
Three, summary of the invention
The purpose of this utility model provides a kind of improved lifting-putting fishing tool capable of withdrawing, shortcoming or deficiency that it can overcome effectively or avoid existing in the above-mentioned prior art, the underground work of adaptation level well well solves the operation of horizontal well unfreezing fishing effectively, and underground work is normally carried out.
Lifting-putting fishing tool capable of withdrawing described in the utility model, comprise top connection, center-pole, spring, pressure cap, track pin, change, anchor fluke and drag for bar, described center-pole one end is connected in and drags on the bar, the other end is connected in the top connection, drags for bar and is installed on spring, pressure cap, track pin, change and anchor fluke outward from top to bottom in turn.
Wherein, the described bar upper end of dragging for links to each other with center-pole, and the middle part is provided with the length track, and track pin is controlled in this length track by change and moves, and the lower end is the conical head of hole enlargement, and the center is provided with intercommunicating pore.Described anchor fluke upper end is fixed on the track that drags for bar by track pin and change, and the outside is installed on pressure cap, and the bottom is the claw type structure of hole enlargement.Described spring is installed in center-pole and is dragged on the bar, and the upper end contacts with top connection, and the lower end is located on the pressure cap.
The utility model has following advantage compared with prior art:
1, is designed to center-pole and fishing rod is stressed, guarantees that anchor fluke reliably withdraws from, and is not damaged;
2, design back-moving spring, overcome effectively and salvage caducous problem when successfully the back pulls out of hole, improved fishing success ratio.
Four, description of drawings
Accompanying drawing is the utility model structural representation.
Five, the specific embodiment
Consult accompanying drawing, a kind of lifting-putting fishing tool capable of withdrawing, comprise top connection, center-pole, spring, pressure cap, track pin, change, anchor fluke and drag for bar, center-pole 2 one ends are connected in and drag on the bar 8, the other end is connected in the top connection 1, drags for bar and is installed on spring 3, pressure cap 4, track pin 5, change 6 and anchor fluke 7 outward from top to bottom in turn.
Drag for bar 8 upper ends and link to each other with center-pole 2, the middle part is provided with the length track, and track pin 5 is controlled in this length track by change 6 and moves, and the lower end is the conical head of hole enlargement, and the center is provided with intercommunicating pore.Anchor fluke 7 upper ends are fixed on the track that drags for bar 8 by track pin 5 and change 6, and pressure cap 4 is installed in the outside, and the bottom is the claw type structure of hole enlargement.Spring 3 is installed in center-pole 2 and is dragged on the bar 8, and the upper end contacts with top connection 1, and the lower end is located on the pressure cap 4.
Claims (4)
1, a kind of lifting-putting fishing tool capable of withdrawing, comprise top connection, center-pole, spring, pressure cap, track pin, change, anchor fluke and drag for bar, it is characterized in that described center-pole one end is connected in drags on the bar, the other end is connected in the top connection, drags for bar and is installed on spring, pressure cap, track pin, change and anchor fluke outward from top to bottom in turn.
2, lifting-putting fishing tool capable of withdrawing according to claim 1, it is characterized in that the described bar upper end of dragging for links to each other with center-pole, the middle part is provided with the length track, and track pin is controlled in this length track by change and moves, the lower end is the conical head of hole enlargement, and the center is provided with intercommunicating pore.
