Abstract
The utility model relates to a fishing tool, in particular to a fishing socket for borehole operation. The technical scheme of the utility model is that the fishing socket for borehole operation comprises an upper joint, a socket body, a slip and a guiding shoe. The upper joint is connected with the socket body where the slip is fixed inside. The guiding shoe is connected with the lower part of the socket body. A limiting base is fixed between the upper joint and the slip through a pin. A spacer bush is arranged between the slip and the guiding shoe. A spring is arranged between the upper joint and the spacer bush. The fishing socket provided by the utility model has the advantages that the fishing socket for borehole operation cannot only fish and buckle reversely, but also release the fish and circulate a flushing fluid, and is simple in structure, convenient to operate and rapid, and has a high fishing success rate and is not limited by fields and the like.
Description
Technical field
The utility model relates to down-hole, a kind of oil field fishing tool, particularly a kind of underground work fishing socket.
Background technology
At present; Drilling tool or other tubing string well accident that ruptures takes place in oil drilling production often, and accident often need salvage fish after taking place, because condition effect such as size, the borehole wall of well are irregular, hole deviations; Fishing socket commonly used at present is difficult to get into the hydrophthalmia of fish; The one, delayed a large amount of valuable accident processing times, the 2nd, possibly make to salvage and lose efficacy, cause salvaging failure.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of underground work fishing socket is provided, and is easy to operate, speed is fast, fishing success ratio is high.
Its technical scheme is: comprise top connection, cylindrical shell, slips and guide shoe; Top connection connects cylindrical shell; The barrel stationary slip, the cylindrical shell bottom connects guide shoe, passes through the dowel fixes limit base between top connection and the slips; Be provided with spacer between described slips and the guide shoe, be provided with spring between top connection and the spacer.
Above-mentioned limit base is provided with a plurality of spacing holes.
The beneficial effect of the utility model is: not only can salvage, back-off but also can discharge fish and can also carry out the flushing fluid circulation, have simple in structure, easy to operate, speed is fast, fishing success ratio is high, do not receive characteristics such as place restriction.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: top connection 1, pin 2, limit base 3, cylindrical shell 4, spring 5, slips 6, spacer 7, guide shoe 8.
The specific embodiment
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model comprises top connection 1, pin 2, limit base 3, cylindrical shell 4, spring 5, slips 6, spacer 7, guide shoe 8; Top connection 1 connects cylindrical shell 4; Cylindrical shell 4 internal fixation slips 6, cylindrical shell 4 bottoms connect guide shoe 8, pass through pin 2 fixed limit seats 3 between top connection 1 and the slips 6; Be provided with spacer 7 between described slips 6 and the guide shoe 8, be provided with spring 5 between top connection 1 and the spacer 7; Described limit base 3 is provided with a plurality of spacing holes.
Its operating principle is: in the salvaging process, meet the junk top of fish when instrument, junk is incorporated into slips through guide shoe; Slips male cone (strobilus masculinus) and cylindrical shell inner conical surface are thrown off, and slips be compelled distending, in the junk entering slips; On carry drill string, the corresponding flank of tooth has relative displacement in the slips external spiral zigzag conical surface and the cylindrical shell, makes slips shrink card and stings junk; Realize salvaging, a plurality of spacing holes that limit base 3 is provided with can prevent the slips dislocation, guarantee normally to salvage.
