Description
Technical field
The present invention relates to a kind of drilling equipment, particularly relate to a kind of wire rope conveying-type blanking plug.
Background technology
In oil drilling exploitation is produced, there will be a lot of high pressure wells, because down-hole Operating Pressure has more risk, require higher to the sealing performance of equipment and personnel's construction safety.At present, when carrying out workover treatment, needing to use water pump vehicle, utilizing the mode of Hydraulic transportation to be driven in down-hole oil tube by blanking plug, because the down-hole degree of depth is darker, the device that results in blockage can not be located well in oil pipe, easily causes site error, impact blocking and sealing effectiveness, existing blanking plug in use sealing effectiveness is bad, can not realize salvaging, and not easily take out in oil pipe, easily cause oil pipe to scrap.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of accurate positioning, salvage wire rope conveying-type blanking plug easily.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: wire rope conveying-type blanking plug, comprise: center-pole and foot piece, the upper end of described foot piece is connected with the lower end of center-pole, the lower end, lower end of described foot piece is provided with conical nose, caulking gum is had in the connecting portion arranged outside of described foot piece and center-pole, lower cone is had in the arranged outside of described caulking gum upper end center bar, the slips cooperatively interacted with lower cone is had in the arranged outside of described lower cone upper end center bar, in the outside of described slips upper end center bar, upper fixed seat is provided with transition joint, center-pole arranged outside between fixed seat and transition joint has pressure ring and locks tooth, described transition joint is movably set with fixture block by rotating shaft, quarter butt is connected with at the threaded upper ends of described center-pole, the arranged outside of quarter butt has upper joint sleeve on described, shear pin is provided with between described upper joint sleeve and upper quarter butt, the lower end outside of described upper joint sleeve is provided with overcoat, epicone cap is connected with at the threaded upper ends of described upper joint sleeve, described epicone cap is provided with wire rope connecting hole.
Advantage of the present invention is: above-mentioned wire rope conveying-type blanking plug, utilizes steel wire traction, and diameter little Yi enters any degree of depth in down-hole, accurate positioning, can not cause site error, ensure blocking and sealing effectiveness, it is convenient to salvage, conveniently take out in oil pipe, can recycle, use cost reduces.

In figure: 1, center-pole, 2, foot piece, 3, conical nose, 4, caulking gum, 5, lower cone, 6, slips, 7, upper fixed seat, 8, transition joint, 9, pressure ring, 10, lock tooth, 11, rotating shaft, 12, fixture block, 13, upper quarter butt, 14, upper joint sleeve is had, 15, shear pin, 16, overcoat, 17, epicone cap, 18, wire rope connecting hole, 19, wire rope.
Detailed description of the invention
Particular content of the present invention is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, wire rope conveying-type blanking plug, comprise: center-pole 1 and foot piece 2, the upper end of described foot piece 2 is connected with the lower end of center-pole 1, the lower end, lower end of described foot piece 2 is provided with conical nose 3, caulking gum 4 is had with the connecting portion arranged outside of center-pole 1 at described foot piece 2, lower cone 5 is had in the arranged outside of described caulking gum 4 upper end center bar 1, the slips 6 cooperatively interacted with lower cone 5 is had in the arranged outside of described lower cone 5 upper end center bar 1, in the outside of described slips 6 upper end center bar 1, upper fixed seat 7 is provided with transition joint 8, center-pole 1 arranged outside between fixed seat 7 and transition joint 8 has pressure ring 9 and locks tooth 10, described transition joint 8 is movably set with fixture block 12 by rotating shaft 11, quarter butt 13 is connected with at the threaded upper ends of described center-pole 1, the arranged outside of quarter butt 13 has upper joint sleeve 14 on described, shear pin 15 is provided with between described upper joint sleeve 14 and upper quarter butt 13, the lower end outside of described upper joint sleeve 14 is provided with overcoat 16, epicone cap 17 is connected with at the threaded upper ends of described upper joint sleeve 14, described epicone cap 17 is provided with wire rope connecting hole 18.
When above-mentioned wire rope conveying-type blanking plug uses, wire rope 19 is connected with blanking plug by wire rope connecting hole 18, the position needing blocking will be arrived under blanking plug by wire rope 19, upwards blanking plug is pulled by wire rope 19, the fixture block 12 on blanking plug is made to be stuck in tubing coupling gap, fixture block 12 is moved down by slips 6 and cooperatively interacts with lower cone 5, thus make the lower end of slips 6 be supported on tube inner wall, caulking gum 4 pairs of tube inner walls seal, lock tooth 10 plays locking effect, after wire rope 19 pulling force upwards acquires a certain degree, shear pin 15 can be cut off, thus quarter butt 13 and upper joint sleeve 14 are separated from each other, thus by upper joint sleeve 14, overcoat 16 and epicone cap 17 promote and salvage.
Above-mentioned wire rope conveying-type blanking plug, utilizes steel wire traction, and diameter little Yi enters any degree of depth in down-hole, and accurate positioning can not cause site error, ensures blocking and sealing effectiveness, and it is convenient to salvage, and conveniently takes out in oil pipe, can recycle, and use cost reduces.
