Abstract
The utility model provides an oil pumping well eccentric wearing preventing device, which comprises an upper joint (1), upper positioning teeth (2), upper teeth (3), a wear-resistance body (4), lower teeth (5), a center rod (6), lower positioning teeth (7) and a lower joint (8). The oil pumping well eccentric wearing preventing device is characterized in that the oil pumping well eccentric wearing preventing device is in a cylindrical structure, the upper end and the lower end of the center rod (6) are respectively provided with the upper joint (1) and the lower joint (8), the upper joint (1) and the lower joint (8) are respectively provided with internal threaded holes, and the wear-resistance body (4) is sheathed in the center of the center rod (6) and is positioned between the upper joint (1) and the lower joint (8). The oil pumping well eccentric wearing preventing device has the advantages that the design is novel, the wear-resistance time is long, the abrasion caused by direct contact of a sucker rod and an oil pipe is avoided, the service life of the sucker rod and the oil pipe is prolonged, the normal production of an oil well is maintained, the workover-free period of the oil well is prolonged, the operation maintenance cost of the oil well is saved, and the crude oil yield is increased.
Description
Technical field
The utility model relates to the abrasionproof facility of oil exploitation pumpingh well bar, oil pipe, especially a kind of preventing offset wear pumping well device.
Background technology
Existing sucker rod, oil conduit wear prevention device kind are more, but at the scene in use procedure, the abrasionproof effect is poor, still there is the problem of local heavy wear, cause the damage of sucker rod, oil pipe, disconnected taking off, directly affect the normal production of pumpingh well, cause the oil well operation maintenance cost to increase.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of preventing offset wear pumping well device is provided.
The utility model comprises: top connection, upper positioning tooth, upper tooth, wear-resistant body, lower tooth, center-pole, lower positioning tooth, lower contact.Its preventing offset wear pumping well device is cylindrical-shaped structure, and the center-pole upper and lower end respectively is provided with top connection, lower contact, and top connection and lower contact are equipped with internal thread hole, and wear-resistant body is enclosed within the central authorities of center-pole, between top connection and lower contact.
Top connection lower end in above-mentioned preventing offset wear pumping well device is provided with positioning tooth.
Wear-resistant body in above-mentioned preventing offset wear pumping well device is for " waist drum ”Zhuan， center is provided with through hole, and upper and lower end respectively is provided with tooth and lower tooth, and upper tooth coordinates with upper positioning tooth, and lower tooth coordinates with lower positioning tooth.
Lower contact in above-mentioned preventing offset wear pumping well device or be made as external screw thread, upper end is provided with lower positioning tooth.
Upper positioning tooth in above-mentioned preventing offset wear pumping well device, upper tooth, lower tooth, lower positioning tooth are zigzag.
Wear-resistant body in above-mentioned preventing offset wear pumping well device is sleeved on center-pole, rotation or upper and lower slip on center-pole, when rod string is supreme, during bottom dead centre, and wear-resistant body is respectively to the upper and lower dead point of center-pole, and rotate to an angle, wear-resistant body all the time around center-pole along a direction rotation, realize the uniform wear of wear-resistant body.
The beneficial effects of the utility model are: modern design, the wear-resistant time is long, avoids sucker rod, oil pipe straight
Contact and produce wearing and tearing, extending the application life of R a T, keeping oil well normally to produce, prolongation
Oil well repair free period, save the oil well operation maintenance cost, increases crude output.
Description of drawings
Fig. 1-the utility model master TV structure schematic diagram.
In figure, 1. top connection, 2. go up positioning tooth, 3. goes up tooth, 4. wear-resistant body, and 5. lower tooth, 6. center-pole, 7. descend positioning tooth, 8. lower contact.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, the preventing offset wear pumping well device is by top connection 1, upper positioning tooth 2, and upper tooth 3, wear-resistant body 4, lower tooth 5, center-pole 6, lower positioning tooth 7, lower contact 8 form.Its preventing offset wear pumping well device is cylindrical-shaped structure, and center-pole 6 upper and lower ends respectively are provided with top connection 1, lower contact 8, and top connection 1 and lower contact 8 are equipped with internal thread hole, and wear-resistant body 4 is enclosed within the central authorities of center-pole 6, between top connection 1 and lower contact 8.During operation, the preventing offset wear pumping well device is connected in the middle of rod string, according to well rod, oil pipe eccentric wear situation, determines spacing distance and quantity.
