Abstract
The utility model relates to coiled tubing dragging and well-descending equipment, in particular to a coiled tubing clamping and well-descending device. According to the technical scheme, the coiled tubing clamping and well-descending device comprises a center shaft, a supporting plate, multiple groups of clamping pieces, a corrugated pipe, a connecting rod, a tensioning ring, a ring sleeve, a steel wire rope and a spring, wherein the conical corrugated pipe is fixed to the center shaft, the corrugated pipe is provided with a spiral groove, the clamping pieces are arranged outside the spiral groove, the connecting rod is horizontally arranged in the spiral groove, the connecting rod is connected with the clamping pieces in series, the supporting plate is fixed outside the clamping pieces, one end of the connecting rod is connected with the center shaft through the spring, the other end of the connecting rod is connected with the tensioning ring, the ring sleeve is arranged outside the tensioning ring, and the tensioning ring is connected with the steel wire rope. The coiled tubing clamping and well-descending device has the advantages that there is no need to dismount and mount coiled tubing every time, so that time and labor are saved, labor intensity is greatly relieved, and the efficiency of coiled tubing well-descending operation is improved.
Description
Technical field
The utility model relates to a kind of oil pipe and draws the equipment of going into the well, and particularly a kind of coiled tubing clamps downhole device.
Background technology
When coiled tubing G.I.H, need to draw by tractor, conventional tractor is to produce and move by driven by power downhole electrical motor at present, normally power supply is on ground, by cable, electric power is passed to down-hole, cable puller is can produce in down-hole the electromechanical assembly of concentrating tractive force after a kind of startup, coiled tubing is as the drilling rod of coiled tubing drilling machine, carry out continuous tubing drill well operations up to drawing and reclaim less coiled tubing once at each new well location, coiled tubing often need be dismantled and be installed, remove and install and waste time and energy, cause labour intensity large, affect operating efficiency.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of coiled tubing to clamp downhole device.
Its technical scheme is: comprise central axis, gripper shoe, intermediate plate, bellows, connecting rod, tensioning ring, ring set, wire rope, spring, on described central axis, fix taper bellows, described bellows is provided with spiral slot, described helicla flute outside is provided with many group intermediate plates, spiral fluted inner horizontal is provided with connecting rod, described connecting rod serial connection intermediate plate, the external stability gripper shoe of intermediate plate, one end of described connecting rod connects central axis by spring, the other end of connecting rod connects tensioning ring, the outside of tensioning ring is provided with ring set, described tensioning ring connecting steel wire ropes.
Above-mentioned intermediate plate comprises the first brace and the second brace, and the first described brace is connected by rotating shaft with the second brace.
The beneficial effects of the utility model are: do not need coiled tubing to be dismantled and installed at every turn, and time saving and energy saving, alleviate labour intensity large, improve the oil pipe operating efficiency of going into the well.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: central axis 1, gripper shoe 2, intermediate plate 3, bellows 4, connecting rod 5, tensioning ring 6, ring set 7, wire rope 8, spring 9.
Accompanying drawing 2 is structural representations of intermediate plate;
In upper figure: the first brace 3.1, the second brace 3.2, rotating shaft 3.3.
The specific embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises central axis 1, gripper shoe 2, intermediate plate 3, bellows 4, connecting rod 5, tensioning ring 6, ring set 7, wire rope 8, spring 9, on described central axis 1, fix taper bellows 4, described bellows 4 is provided with spiral slot, described helicla flute outside is provided with many group intermediate plates 3, spiral fluted inner horizontal is provided with connecting rod 5, described connecting rod 5 is connected in series intermediate plate 3, the external stability gripper shoe 2 of intermediate plate 3, one end of described connecting rod 5 connects central axis 1 by spring 9, the other end of connecting rod 5 connects tensioning ring 6, the outside of tensioning ring 6 is provided with ring set 7, described tensioning ring 6 connecting steel wire ropes 8.
Wherein, intermediate plate 3 comprises the first brace 3.1 and the second brace 3.2, and the first described brace 3.1 is connected by rotating shaft 3.3 with the second brace 3.2.
In the course of work, pull tensioning ring by wire rope, the action of tensioning ring drivening rod, connecting rod pulls the intermediate plate of serial connection, intermediate plate is launched, promote outer support plate and outwards stretch, thereby make gripper shoe block coiled tubing, pull coiled tubing to complete lower well operations, use simple, effective, do not need coiled tubing to be dismantled and installed at every turn, time saving and energy saving, alleviate labour intensity large, improved the oil pipe operating efficiency of going into the well.
