Abstract
The utility model relates to the technical field of oil field salvage devices and discloses a salvage device capable of avoiding clamping. The salvage device comprises an upper connector, a barrel and a rubber baffle disc, wherein the inner side of the lower end of the upper connector is fixedly mounted with the outer side of the upper end of the barrel; at least two salvage hooks are fixed on the outer side of the barrel from top to bottom; a guide body is fixed on the lower end of the barrel; an annular groove is formed in the barrel above the salvage hook at the upmost end; the inner end of the rubber baffle disc is fixed in the annular groove; the radius of the rubber baffle disc is larger than the distance between the salvage hooks and the axis of the barrel; at least one inclined through hole is distributed in the lower part of the barrel; at least one guide hole is distributed in the guide body. The salvage device has the advantages that the structure is reasonable, the use is convenient, the clamping condition can be avoided due to the arrangement of the rubber baffle disc, the success rate of salvage work is improved, and the hidden danger that salvaged cables move upwards to wind a drill tool above the rubber baffle disc can be effectively reduced due to the arrangement of occulting bars.
Description
Technical field
The utility model relates to oilfield salvage device technique field, is a kind of anti-chance card fishing device.
Background technology
Oil field salvaging thatch used all is with block plate at present, the effect of block plate be can by salvaging to cable, steel wire or head of steel wire rope be blocked in the below of block plate, the drilling tool of string and then winding block plate top on the cable that effectively prevents from being salvaged, block plate is the steel block plate be fixed by welding on the thatch bar, because the hardness of steel block plate is high, be not easy wearing and tearing and distortion.In the process that down-hole is used, when the well inner sleeve be out of shape, salvage thatch and just there will be and be hampered or meet and block phenomenon, because salvaging thatch and block plate are the structures be connected as a single entity, so the staff is difficult to the salvaging thatch unfreezing will be stuck in sleeve pipe.
Summary of the invention
The utility model provides a kind of anti-chance card fishing device, has overcome the deficiency of above-mentioned prior art, and it can effectively solve owing to salvaging thatch and block plate is that the structure be connected as a single entity is difficult to be stuck in the problem of the salvaging thatch unfreezing in sleeve pipe.
The technical solution of the utility model is achieved like this: a kind of anti-chance card fishing device, comprise top connection, cylindrical shell and rubber block plate, the inboard outside, upper end with cylindrical shell, the lower end of top connection is fixedly installed togather, the outside at cylindrical shell is fixed with the recovery hook that is no less than two from top to bottom, lower end at cylindrical shell is fixed with guide body, on the cylindrical shell above the recovery hook of the top, annular groove is arranged, the inner of rubber block plate is fixed in annular groove, the radius of rubber block plate is greater than the distance between recovery hook and tubular axis, be distributed with the oblique through hole that is no less than in the bottom of cylindrical shell, be distributed with the bullport that is no less than on guide body.
The outside of above-mentioned rubber block plate is provided with blend stop.
Above-mentioned blend stop is steel wire.
The inboard outside, upper end with cylindrical shell, the lower end of above-mentioned top connection is fixedly installed togather by screw thread.
The lower end of above-mentioned cylindrical shell is fixed with guide body by screw thread.
The utility model is rational in infrastructure, easy to use, can avoid meeting card by the rubber block plate is set, thereby improve the success rate of salvage, by blend stop is set, can effectively reduce on the cable of being salvaged the hidden danger of going here and there and then be wound around rubber block plate top drilling tool.
The accompanying drawing explanation
Fig. 1 is that master of the present utility model looks the half section structural representation.
Coding in figure is respectively: 1 is top connection, and 2 is cylindrical shell, and 3 is the rubber block plate, and 4 is recovery hook, and 5 is guide body, and 6 is oblique through hole, and 7 is bullport, and 8 is blend stop.
The specific embodiment
As shown in Figure 1, this anti-card fishing device of meeting comprises top connection 1, cylindrical shell 2 and rubber block plate 3, the inboard outside, upper end with cylindrical shell 2, the lower end of top connection 1 is fixedly installed togather, be fixed with the recovery hook 4 that is no less than two from top to bottom in the outside of cylindrical shell 2, be fixed with guide body 5 in the lower end of cylindrical shell 2, on the cylindrical shell 2 above the top recovery hook 4, annular groove is arranged, the inner of rubber block plate 3 is fixed in annular groove, the radius of rubber block plate 3 is greater than the distance between recovery hook 4 and cylindrical shell 2 axis, be distributed with the oblique through hole 6 that is no less than in the bottom of cylindrical shell 2, be distributed with the bullport 7 that is no less than on guide body 5.Like this, when the well inner sleeve is out of shape, adopts rubber block plate 3 can avoid meeting card, thereby improved the success rate of salvage.
As shown in Figure 1, the outside of rubber block plate 3 is provided with blend stop 8.Like this can by salvaging to cable, steel wire or head of steel wire rope be blocked in the below of rubber block plate 3, string and then be wound around the drilling tool of rubber block plate 3 tops on the cable that has effectively prevented from being salvaged.
As shown in Figure 1, as required, blend stop 8 is steel wire.
As shown in Figure 1, for the ease of installation and removal, the inboard outside, upper end with cylindrical shell 2, the lower end of top connection 1 is fixedly installed togather by screw thread.
As shown in Figure 1, for the ease of installation and removal, the lower end of cylindrical shell 2 is fixed with guide body 5 by screw thread.
