Embodiment Construction

[0010] Combine below figure 1 The present invention is further described:

[0011] The inner diameter of the ultra-high molecular weight polyethylene pipe with shape memory function is larger than the outer diameter of the external thread shoulder 4 and the diameter of the flange 3 of the sucker rod before being heated, and the pipe is placed on the sucker rod 1 and heated. The pipe material returns to its original shape under thermal stimulation to form an ultra-high molecular weight polyethylene protective layer 2 .

Abstract

The invention discloses a sucker rod with an ultra-high molecular weight polyethylene protective layer and belongs to the technical field of oil extraction equipment. The sucker rod is characterized in that a ultra-high molecular weight polyethylene plastic pipe with a shape memory function is used, the pipe is sleeved on the sucker rod and heated, the pipe is recovered to an original shape under the stimulation of heat, and accordingly, the sucker rod is provided with the ultra-high molecular weight polyethylene protective layer.

Description

technical field [0001] The invention belongs to the technical field of oil production equipment and relates to a sucker rod for a pumping unit. Background technique [0002] At present, the oil production equipment used in domestic oilfields is still dominated by the beam pumping unit. The sucker rod is one of the important components of the beam pumping unit. The corrosion resistance and wear resistance of the sucker rod are important A key indicator of sucker rod life. Protective paint is used to protect the surface of sucker rods in traditional technology, and the service life of sucker rods is limited. Contents of the invention [0003] The object of the present invention is to provide a sucker rod equipped with a protective layer of ultra-high molecular weight polyethylene. [0004] Technical scheme of the present invention is: [0005] UHMWPE plastic pipe with shape memory function is adopted, the inner diameter of the pipe is larger than the outer diameter of the...
