Abstract
A wire rope fishing tool used under the condition of the complicated structure of the wire rope for workover in the oil field is provided with an outer cylinder, and is characterized in that the innerwall of the outer cylinder is provided with a plurality of fishing inner hooks, the upper end of the outer cylinder is connected with a screw spindle by a bearing, the lower end of the screw spindleextends out of the lower end surface of the outer cylinder, the lower end of the screw spindle is connected with a cutter head, the upper end of the screw spindle extends out of the upper end surfaceof the outer cylinder, and the upper end of the screw spindle is in treaded connection with an upper connector. The utility model has simple and reliable structure, is convenient to produce and operate, and can effectively improve the process of the workover.
Description
Technical field
The utility model belongs to the oil field well workover and adopts this instrument down with the steel cord structure complicated situation.
Background technology
The instrument of in the past salvaging wire rope is outer hook, interior hook, inside and outside assembly hook, and single hook etc. are salvaged various rope classes in sleeve pipe or oil pipe, but because bottom hole falling article is too much, and complex structure adopts this class instrument just to be difficult for having salvaged, its reliability is difficult to guarantee.
The utility model content
The utility model purpose is to provide a kind of can reliably salvage complex structure, wire rope fisher easy to use.
The utility model is hook in outer tube inner wall is provided with some salvagings, the upper end of urceolus connects screw mandrel by bearing, the lower end of described screw mandrel stretches out in the lower surface of urceolus, lower end at screw mandrel connects cutter head, the upper end of described screw mandrel stretches out in the upper surface of urceolus, and screw thread is connected with top connection in the upper end of screw mandrel.
The utility model urceolus hangs on the screw mandrel shoulder, and screw mandrel is by the rotation of bearing carry-over moment, and there is cutter head the screw mandrel lower end, is used for guiding and cuts off wire rope.Transfer in the process at the utility model, the cutter head of screw mandrel lower end at first inserts steel wire rope loop, cut off wire rope, after confirming that suspending weight descends, beat on oil pipe or drilling rod with pipe wrench, after clockwise rotating 20 circles～30 circles, because the effect of bearing, screw mandrel drives wire rope class fish and rotates on the interior hook of the salvaging that promptly is wrapped in hook body and urceolus, slowly the upper lifting pipe post is observed the suspending weight variation, get final product the upper lifting pipe post greatly to well head as slight change of suspending weight, whole salvaging process successfully finishes, and salvages action thereby finish.
The utility model is simple in structure, reliable, and convenient production, handled easily can effectively improve the well workover process.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model welds hook 4 in some salvagings at the inwall of urceolus 6, and the upper end of urceolus 6 connects screw mandrel 3 by plane bearing 2.
The lower end of screw mandrel 3 stretches out in the lower surface of urceolus 6, connects cutter head 5 in the lower end of screw mandrel 3.The upper end of screw mandrel 3 stretches out in the upper surface of urceolus 6, and screw thread is connected with top connection 1 in the upper end of screw mandrel 3.
