Abstract
The utility model relates to an in-built centralizer, including a tubing collar (1) and characterized in that the tubing collar (1) is provided with a wear-resistant liner (2). The utility model has a convenient installation, a reliable usage, prevents a sucker rod from wearing as well as causes no wear to an oil pipe, prolongs the service life of the sucker rod and the oil pipe and reduces the cost.
Description
(1) technical field: the utility model relates to a kind of centralizer, relates in particular to a kind of built-in centralizer.
(2) background technology: at present; because rod pumping system is in entire work process; oil well all exists deflection in various degree; caused the friction between banded sucker rod and the oil pipe tube wall; the wearing and tearing of banded sucker rod have promptly been aggravated; the oil pipe that worn and torn again, and present employed centralizer has only been protected sucker rod, does not solve the wear problem of oil pipe.
(3) technology contents: the purpose of this utility model is to improve the deficiency of above-mentioned prior art and provides a kind of easy for installation, use reliable, prevent that promptly the sucker rod wearing and tearing from making oil pipe not have wearing and tearing again, strengthen the application life of sucker rod and oil pipe, reduce the built-in centralizer of cost.
The purpose of this utility model can reach by following measure: a kind of built-in centralizer, it comprises tubing coupling 1, it is characterized in that being provided with in the tubing coupling 1 wear-resistant liner 2.
The utility model can produce following good effect compared with the prior art: because the utility model is provided with wear-resistant liner, promptly prevented the wearing and tearing of sucker rod, oil pipe is worked under the state that does not have wearing and tearing, strengthened application life, reduced cost, and easy for installation, use reliable.
(4) description of drawings:
Accompanying drawing is a structural representation of the present utility model.
(5) specific embodiment:
Embodiment 1: a kind of built-in centralizer (referring to accompanying drawing), it comprises tubing coupling 1, is provided with wear-resistant liner 2 in the tubing coupling 1.During use, after being placed with wear-resistant liner 2 in the tubing coupling 1, connect oil pipe at the two ends of tubing coupling 1 again, so banded sucker rod only rubs with wear-resistant liner 2, the oil pipe that can not wear and tear in order to reduce wear, increases wear-resisting, heatproof, the acid-alkali-corrosive-resisting degree of centralizer, strengthen its application life, wear-resistant liner can adopt thermosetting composite carbon fiber material to make.
Claims (3)
1, a kind of built-in centralizer, it comprises tubing coupling (1), it is characterized in that being provided with in the tubing coupling (1) wear-resistant liner (2).
2, a kind of built-in centralizer according to claim 1 is characterized in that described wear-resistant liner (2) adopts thermosetting composite carbon fiber material to make.
3, a kind of built-in centralizer according to claim 1 is characterized in that described wear-resistant liner (2) adopts composite thermoplastic carbon fiber material to make.
