Abstract

The embodiment of the invention provides a flexible bend-resisting sucker rod and a manufacturing method for the sucker rod and belongs to the technical field of oil exploitation equipment. The flexible bend-resisting sucker rod comprises an elastic macromolecular protective jacket and a steel wire rope, wherein the macromolecular protective jacket is made from an elastic and anti-corrosion material; the steel wire rope is formed by winding multiple strands of steel wires; the elastic macromolecular protective jacket is embedded into and sleeved on the steel wire rope in the manner of injection molding. The steel wire rope is formed by winding multiple strands of steel wires and the elastic macromolecular protective jacket is embedded into and sleeved on the steel wire rope in the manner of injection molding, so that the service life of the flexible bend-resisting sucker rod is greatly prolonged and the applicability in practical use is greatly promoted.

Description

technical field [0001] The invention relates to the technical field of oil exploitation equipment, in particular to a flexible and anti-bending sucker rod and a method for manufacturing the sucker rod. Background technique [0002] With the development and improvement of science and technology, sucker rods have been widely used in oil extraction equipment. [0003] In the prior art, most of the traditional sucker rods are not flexible, and cannot be bent or excessively bent, otherwise the sucker rod will be broken. The sucker rod is not flexible, which greatly affects the applicability of the sucker rod in transportation, installation and use. In addition, the traditional part of the sucker rod is also flexible, because of its flexible characteristics, it can be bent or coiled. However, the number of times of coiling or bending of the traditional flexible sucker rod is limited, and after multiple coiling or bending, the surface of the sucker rod is likely to break, which i...
