Abstract
The invention relates to a hook fishing device for an oil gas well. When an oil gas well internal pipe column is blocked, tools, instruments, pipe columns and the like fall into the well, a corresponding fishing device needs to be adopted for fishing objects falling into the well, fishing expense is high, and therefore the fishing device capable of dealing with any underground accidents is needed, and the fallen objects such as cables can not be fished successfully with a common fishing device. The hook fishing device comprises an upper connector and a barrel body, wherein the lower end of the upper connector is connected with the barrel body, an inverted hook is arranged on the barrel body, and a hemispherical check ring is sleeved on the barrel body. The hook fishing device is simple in structure, increases the length of a lengthened joint rod and changes the length of the lengthened joint rod according to actual needs, and prevents the short cables from slipping from the inverted hook by means of the check ring.
Description
Technical field
The present invention relates to a kind of hook class fisher for oil gas water well.
Background technology
Tubing string is met card in the oil gas water well well, the phenomenons such as instrument, instrument and tubing string etc. drop in well, need to adopt corresponding fishing tool to pull trouble of lost tool in hole out, high because of salvage expenses, so need a kind of fisher that can process at any down-hole accident, adopt general fisher successfully to salvage for the salvaging of the junk of cable.
Summary of the invention
Technical problem solved by the invention is to provide a kind of simple in structure, is applicable to the junk of cable, prevents from grabbing the hook class fisher that is used for oil gas water well that the junk that drags for drops.
For solving above-mentioned technical problem, the technical scheme that the present invention takes:
A kind of hook class fisher for oil gas water well, its special character is: comprise top connection, cylindrical shell, the lower end of top connection connects cylindrical shell, is provided with barb on cylindrical shell, is arranged with hemispheric back-up ring on cylindrical shell.
Be provided with the lengthening pole between above-mentioned top connection and cylindrical shell.
Above-mentioned barb is arranged on cylindrical shell by active pin shaft.
Compared with prior art, of the present invention simple in structure, increase to lengthen according to actual needs pole and change length, back-up ring is set prevents the landing from the barb of shorter cable.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, the present invention includes top connection 1, cylindrical shell 2, the lower end of top connection 1 connects cylindrical shell 2, is provided with barb 3 on cylindrical shell 2, is arranged with hemispheric back-up ring 4 on cylindrical shell 2.
Be provided with the lengthening pole between above-mentioned top connection 1 and cylindrical shell 2.
Above-mentioned barb 3 is arranged on cylindrical shell 2 by active pin shaft.
Workflow:
After the fisher entering tool is salvaged in the chamber, suitably increase the pressure of the drill and rotation drilling tool, fall within cable in well, wire rope, steel wire for logging etc. and lead to drag by barb and elevate, even if but landing on barb when running into shorter cable, the cable that also has back-up ring then to drop improves the efficient of salvaging.
