Fig. 2 is the top view that sucker rod of the present utility model turns over inserted to play dipper.
Detailed description of the invention
In order to better understand the purpose of this utility model, structure and function, below in conjunction with accompanying drawing, inserted to play dipper being turned over to sucker rod of the present utility model and does further detailed description.
As depicted in figs. 1 and 2, sucker rod of the present utility model turns over inserted to play dipper for salvaging the exposed and bending sucker rod in down-hole, comprise the salvaging cylindrical shell 1 being positioned at inside pipe casing, salvage in the internal chamber of cylindrical shell 1 and be horizontally arranged with turnover panel 2, one end of turnover panel 2 is hinged with the internal face salvaging cylindrical shell 1, the other end is freely arranged, one end that turnover panel 2 is freely arranged is formed with snap openings 4, the width of snap openings 4 is greater than the width of sucker rod, the outside wall surface projection of sucker rod has box cupling (not shown), the diameter of box cupling is greater than the diameter of sucker rod, the width of snap openings 4 is less than the width of the box cupling on sucker rod, snap openings 4 on turnover panel 2 can be buckled in the bottom of the box cupling on sucker rod, rise to drive sucker rod.Wherein, the snap openings 4 on turnover panel 2 is in " U " shape.
Further, the internal face of salvaging cylindrical shell 1 is fixedly installed limited block 3, limited block 3 is positioned at the bottom of turnover panel 2, the lower surface of turnover panel 2 is resisted against on limited block 3, turnover panel 2 is subject to the resistance of rod collar in cylindrical shell 1 salvaging, the one end that can be hinged around the internal face with salvaging cylindrical shell 1 is upwards rotated.Wherein, limited block 3 is fixedly installed on salvages position corresponding with one end freely arranged of turnover panel 2 on the internal face of cylindrical shell 1, and one end freely arranged of turnover panel 2 is resisted against on limited block 3.
Further, one end of turnover panel 2 is hinged by elastic parts 21 with the internal face salvaging cylindrical shell 1, it should be noted, in the utility model, turnover panel 2 and salvaging cylindrical shell 1 are linked together preferably by spring, when turnover panel 2 upwards rotates by external force, turnover panel 2 is fallen after rise by the elastic reset of spring.
Further, the salvaging cylindrical shell 1 of turnover panel 2 bottom draws cylinder 5 for tapered, the diameter drawing the internal chamber of cylinder 5 reduces from the bottom to top gradually, and the bottom of drawing cylinder 5 is provided with opening, and the sucker rod that need salvage can enter the internal chamber of salvaging cylindrical shell 1 from the opening of the bottom of drawing cylinder 5.In addition, the internal diameter drawing cylinder 5 top is identical with the external diameter of turnover panel 2, so that sucker rod can pass through turnover panel 2 smoothly.
Further, the salvaging cylindrical shell 1 on turnover panel 2 top is casing section mill 6, the diameter of the internal chamber of casing section mill 6 is identical with the external diameter of turnover panel 2, casing section mill 6 extends the length of salvaging cylindrical shell 1, can as much as possiblely enter in casing section mill 6 to realize sucker rod top, so that to the object that the box cupling of sucker rod bottom is salvaged, improve the success rate of salvaging.
Further, the internal face of the snap openings 4 of turnover panel 2 is provided with skid resistant course, skid resistant course is the trickle alloy being laid on opening part, prevents sucker rod from proposing the slippage because pressure is excessive in process upper.In addition, the edge of turnover panel 2 is provided with back-up coat, increases the thickness of turnover panel, prevents from being strutted by sucker rod, guarantee that spring can normally work, reset smoothly to make turnover panel.
Below the course of work that sucker rod of the present utility model turns over inserted to play dipper is described in detail:
Fishing tool is transferred the tram to needing to salvage sucker rod, after carrying out abundant well-flushing, rotate and salvage cylindrical shell 1, exposed sucker rod or bent rod being introduced salvages in cylindrical shell 1, transfer fishing tool gradually, sucker rod by internal diameter reduce gradually draw cylinder 5 after, because on turnover panel 2, the width of snap openings 4 is less than the width of the box cupling on sucker rod, the box cupling jack-up turnover panel 2 of sucker rod, makes turnover panel 2 upwards can rotate in salvaging cylindrical shell 1; Continue to transfer fishing tool, continue to move up along the casing section mill 4 salvaging cylindrical shell 1 top in sucker rod top, after the box cupling jack-up of sucker rod also passes through the opening of turnover panel 2, turnover panel 2 resets under the elastic force effect of spring, and the snap openings 4 on turnover panel 2 can be buckled on the sucker rod of box cupling bottom; Carry on fishing tool, be applied to sucker rod pulling force and moment of torsion, salvaging or back-off operation are completed to sucker rod.
Sucker rod of the present utility model turns over inserted to play dipper, and what achieve bent rod enters fish and fishing, recovers oily well capacity, has economic benefit, administration measure; Accelerate the progress of heavy repair task, shorten the heavy repair task cycle, improve operation timeliness; Avoid down-hole accident complicated; Reduce operating cost, reduce the expense of workover treatment.
By specific embodiment, the utility model is further described above; but it should be understood that; here concrete description; should not be construed as the restriction to essence of the present utility model and scope; one of ordinary skilled in the art to the various amendments that above-described embodiment is made, belongs to the scope that the utility model is protected after reading this specification.
