Abstract
The utility model provides a novel eccentric wear preventing multiplier for an oil well, which belongs to a component used for oil production in oil fields. The utility model comprises a working barrel body, another barrel body is arranged in the working barrel body, the external diameter of the barrel body is slightly smaller than the internal diameter of the working barrel body, the upper part and the lower part of the barrel are provided with an oil hole and another oil hole, the upper end and the lower end of the barrel body are respectively provided with joints, adjusting rods are respectively fixed on the joints, an alloy powder layer is arranged on the internal surface of the working barrel body and the external surface of the barrel body is provided with a spraying coating layer. The two barrel bodies of the eccentric wear preventing multiplier form a tight clearance fit, because the powder alloy layer and the spraying coating layer exist, the utility model can improve the wear and corrosion preventing performance, the occurrence of the phenomenon of eccentric wear can be effectively relieved, the valid service life of an oil well is extended and the efficiency of oil production work is improved.
Description
Technical field
The utility model provides a kind of parts of oil field oil recovery usefulness, especially a kind of anti-eccentric wear device.
Background technology
Extensively adopt oil pumper sucker rod pumping mode in the oil exploitation process.Sucker rod is installed in the oil pipe of down-hole, moves up and down under the drive of oil pumper on the ground, and the crude oil that the oil well pump of down-hole is pumped is evacuated to ground.Along with developing to the middle and later periods of the part block in oil field, strata pressure reduces, the moisture height of output liquid, adds reasons such as the oil well gradient is big, flex point is many, causes the sucker rod working condition abominable.Therefore rod sag or the tubing bending that causes all can cause the friction of sucker rod and oil pipe, thereby forms eccentric wear.Especially box cupling fracture, dropout because of external diameter is rubbed at first greater than sucker rod, thereby are caused in the box cupling position of sucker rod, make the following sucker rod of box cupling of fracture place fall into and descend.At this moment, must stop production and carry out workover treatment, the shortening that this can cause economic loss and oil well effective storage life causes the reduction of output.In addition, owing to contain a certain amount of corrosivity composition in the crude oil, also can cause the damage of R a T because of corrosion.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of novel used for eccentric wear prevention of oil well synergistic device is provided, and it can alleviate the generation of eccentric wear phenomenon effectively, prolongs the effective storage life of oil well.The utility model is to realize like this, novel used for eccentric wear prevention of oil well synergistic device, it has the work cylindrical shell, there is external diameter to be slightly smaller than another cylindrical shell of work cylinder internal diameter in the work cylindrical shell, the upper and lower part of another cylindrical shell has oilhole and another oilhole respectively, and the upper and lower end of another cylindrical shell has joint respectively, is fixed with adjusting lever on two joints respectively, at the work cylinder inner surface alloy powder layer is arranged, sprayed coating is arranged at another barrel outer surface.
Adopt the novel used for eccentric wear prevention of oil well synergistic device of said structure, matched in clearance is close between two cylindrical shells, because the existence of powder metallurgy layer, sprayed coating is arranged, improved wear-resistant, corrosion resistance, alleviated the generation of eccentric wear phenomenon effectively, prolong the effective storage life of oil well, increased oil producing operation efficient.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
Fig. 2 is the I partial enlarged drawing of Fig. 1.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates structure of the present utility model and operating principle.
As shown in drawings, the novel used for eccentric wear prevention of oil well synergistic device of the utility model, it has work cylindrical shell (1), there is external diameter to be slightly smaller than another cylindrical shell (3) of work cylinder internal diameter in the work cylindrical shell, the upper and lower part of another cylindrical shell has oilhole (4) and another oilhole (5) respectively, and the upper and lower end of another cylindrical shell has joint (6) respectively, is fixed with adjusting lever (2) on two joints respectively, at the work cylinder inner surface alloy powder layer (1-1) is arranged, sprayed coating (3-1) is arranged at another barrel outer surface.
Handle through the mill that spreads out the outside of alloy powder layer, has higher surface flatness.Shoot out layer and be the coating of wear resistant corrosion resistant.The external surface of adjusting lever also can have sprayed coating.
The work cylindrical shell can link together by the screw thread in the joint of its upper and lower end and other oil pipes, becomes the part of whole oil recovery oil pipe.Adjusting lever and other sucker rods link together.Adjusting lever drives another cylindrical shell and moves up and down in the work cylindrical shell, and the crude oil of extraction enters another cylindrical shell in oilhole (5), upwards flows out in another oilhole (4).
