Abstract

The invention discloses a novel sucker rod centralizer which comprises a rod body, a fastening sleeve and a centralizing paraffin-scraping device, wherein the rod body is a hollow tube, a male buckle structure is arranged at one end of the rod body, and a female buckle structure is arranged at the other end of the rod body. The centralizing paraffin-scraping device is sleeved in through one end of a male buckle of a sucker rod, abuts one end of a female buckle of the sucker rod and is fixed by screwing the fastening sleeve. The centralizing paraffin-scraping device is composed of a sleeve main body, a left paraffin scraper and a right paraffin scraper. The novel sucker rod centralizer is reasonable in structural design and remarkable in effect, the paraffin scrapers arranged on the rod body are designed to be in split structures, so that good paraffin scraping effect is ensured and simultaneously good radiating and paraffin removing performances are considered. Simultaneously, the left paraffin scraper and the right paraffin scraper can rotate in the reverse directions so that torsion value on the sucker rod is effectively reduced, the working state of the sucker rod is led to be stable, and the use performance of the sucker rod is led to be remarkable.

Description

Technical field [0001] The invention relates to a sucker rod centralizer, in particular to a new sucker rod centralizer with stable working performance, excellent heat dissipation and wax removal effects, and belongs to the technical field of petroleum accessories. Background technique [0002] The sucker rod moves up and down in the tubing. Due to the elastic deformation of the sucker rod, the sucker rod and the tubing wall are prone to friction, the sucker rod is easy to break, and it is not easy to salvage after entering the tubing, which affects production efficiency. For this reason, people connect a sucker rod centralizer to the sucker rod. The sucker rod centralizer has the characteristics of strong flexibility, friction resistance and corrosion resistance. It contacts the inner wall of the tubing to reduce the friction between the sucker rod and the tubing. , To enhance the oil recovery life of the pumping unit. [0003] With the rapid development of the national economy, ...
