Abstract
The spiral eccentric cone sucker rod fisher is composed of a drill rod joint, a fisher body and a cone pipe, and is characterized in that the upper end part of the fisher body is in threaded connection with the drill rod joint and is fixed or welded by a pin, the lower end part of the fisher body is provided with an arc-shaped guide shoe, a left spiral tooth groove is formed in the inner wall of the fisher body, the cone pipe is not concentric with the drill rod joint, the cone pipe is in threaded connection with the drill rod joint and is fixed by the pin, the minimum distance between the fisher body and the cone pipe is not smaller than 22 mm, the length of the cone pipe is smaller than that of the fisher body, the left spiral tooth groove is formed in the periphery of the cone pipe, the tooth groove of the cone pipe and the tooth groove of the fisher body form a sucker rod spiral track, a sucker.
Description
One, technical field
Used spiral eccentric awl pumping rod salvager when the utility model relates to a kind of rod parting.
Two, background technology
The oil field is in the oil recovery manufacturing process, and what sucker rod used extremely mostly is the discontinuous sucker rod of steel work, and the sucker rod partial wear phenomenon is more serious, the sand card often occurs in the oil field that shakes out easily especially, causes rod broken, and this type of accident rate is high.The top of fish of the sucker rod of fracture usually is irregular, flexural deformation appears, and existing sucker rod socket and three ball fishers requirement top of fish are body or not distortion of top of fish, can not be directly used in non-body of top of fish and top of fish distortion rod parting accident treatment, so the salvaging of sucker rod is to perplex the big problem of work production at present.This difficult problem alleviates workpeople's labour intensity, accelerates well workover speed, shortens the well workover duration, increases economic efficiency, and we have designed " eccentric awl saw screw thread multifunctional pumping rod fisher ", and good through the operation field experiment effect, a difficult problem is satisfactorily resolved.
Three, summary of the invention
The purpose of this utility model is for overcoming the problem that above-mentioned prior art exists, accelerate to salvage sucker rod speed, shorten the well workover duration, rate when improving oil well production has designed a kind of spiral eccentric awl pumping rod salvager.
The technical solution of the utility model realizes in the following manner:
The utility model is by tool joint, fisher body and Taper Pipe are formed, it is characterized in that between fisher body upper end and the tool joint by being threaded and dowel fixes or welding being arranged, its bottom is provided with nock shape guide shoe, its inwall is provided with left-hand screw formula teeth groove, Taper Pipe and tool joint decentraction, be threaded therebetween, and dowel fixes arranged, minimum spacing between fisher body and the Taper Pipe is not less than 22 millimeters, Taper Pipe length is less than the fisher body length, the Taper Pipe periphery is provided with left-hand screw formula teeth groove, the teeth groove of Taper Pipe teeth groove and fisher body constitutes the sucker rod helical trajectory, sucker rod firmly is wrapped in the fisher, makes its winding power bear salvaging load, be convenient to the disconnected sucker rod that takes off is salvaged pit shaft.
The utility model compared with the prior art, design ingenious, reasonable in design, simple in structure, salvage sucker rod reliable, salvage short, success rate 100% of duration, be desirable sucker rod fishing tool.
Four, description of drawings

Five, embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is by tool joint 5, fisher body 1 and Taper Pipe 2 are formed, between fisher body 1 upper end and the tool joint 5 by being threaded, and there is pin 3 to fix or welding, its bottom is provided with nock shape guide shoe 6, its inwall is provided with left-hand screw formula teeth groove, Taper Pipe 2 and tool joint 5 decentraction, be threaded therebetween, and there is pin 4 fixing, minimum spacing between fisher body and the Taper Pipe is not less than 22 millimeters, Taper Pipe length is less than the fisher body length, and the Taper Pipe periphery is provided with left-hand screw formula teeth groove, and the teeth groove of Taper Pipe teeth groove and fisher body constitutes the sucker rod helical trajectory.Sucker rod firmly is wrapped in the fisher, makes its winding power can bear salvaging load, be convenient to the disconnected sucker rod that takes off is salvaged pit shaft.
In salvaging the sucker rod process, the fisher top is during near 0.5 meter left and right sides of top of fish, slowly transfer, and the rotation fishing string, when load decline 5KN-10KN, afterburning rotation fishing string, sucker rod is fully twined along the helical tooth track, dial at last and drag for tubing string, pull sucker rod out, finish the salvaging task.
