Description
Technical field
The utility model relates to a kind of oil field operation fishing tool, particularly a kind of novel down-hole slips fisher.
Background technology
Oil-water well is produced or is examined in the pump maintenance process, broken small workpiece such as plug, pincers tooth, valve ball, well head nut often occur and falls into the situation in the sleeve pipe, so just requires trouble of lost tool in hole is salvaged; In fishing; Because trouble of lost tool in hole is not understood, so just require the fishing range of fishing tool big, existing smallclothes fishing junk instrument can not be brought into play better action in work progress; Often one is not all rightly changed one again, cause the construction period long, operating cost is high.
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 novel down-hole slips fisher is provided, and fishing range is big, reduces operating cost, enhances productivity.
Its technical scheme is: mainly be made up of joint, cylindrical shell, inner seal ring, inner cone, slips, O type cushion rubber, guide shoe; Cylindrical shell top jointing; Barrel is provided with inner seal ring and slips; The cylindrical shell bottom is provided with inner cone, and the bottom of inner cone connects guide shoe, is provided with O type cushion rubber between described inner seal ring and the inner cone.
The beneficial effect of the utility model is: fishing range is big, can realize grabbing dragging for and withdraw from fish in case of necessity, and its function admirable, simple in structure can make the engineering time shorten, and reduces operating cost, enhances productivity.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: joint 1, cylindrical shell 2, inner seal ring 3, inner cone 4, slips 5, O type cushion rubber 6, guide shoe 7.
The specific embodiment
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly is made up of joint 1, cylindrical shell 2, inner seal ring 3, inner cone 4, slips 5, O type cushion rubber 6, guide shoe 7; Cylindrical shell 2 top jointings 1; Cylindrical shell 2 inside are provided with inner seal ring 3 and slips 5; Cylindrical shell 2 bottoms are provided with inner cone 4, and the bottom of inner cone 4 connects guide shoe 7, is provided with O type cushion rubber 6 between described inner seal ring 3 and the inner cone 4.
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, realizes salvaging.
