Sucker rod anti-abrasion alloy protection tube connector with guiding function

Abstract

The invention discloses a sucker rod anti-abrasion alloy protection tube connector with a guiding function. The sucker rod anti-abrasion alloy protection tube connector is characterized in that a leftside sealing sleeve (2) and a right side sealing sleeve (3) are respectively arranged at two sides of a connector main body (1); a left side connecting hole (4) is formed in the left side sealing sleeve (2); the left side connecting hole (4) is internally provided with left side inner threads; the left side connecting hole (4) stretches from the inner part of the left side sealing sleeve (2) to the inner part of the connector main body (1); a right side connecting hole (5) is formed in the right side sealing sleeve (3); the right side connecting hole (5) is internally provided with right sideinner threads; the right side connecting hole (5) stretches from the inner part of the right side sealing sleeve (3) to the inner part of the connector main body (1); a plurality of convex guiding blocks (6) are distributed on the outer surface of the connector main body (1); the guiding blocks (6) and the connector main body (1) are connected into a whole; each guiding block (6) diagonally penetrates through the outer surface of the connector main body (1) from left to right. According to the sucker rod anti-abrasion alloy protection tube connector disclosed by the invention, the abrasion resistance is good, the service life is long, the strength is high, and the corrosion resistance is good.

Description

technical field [0001] The invention relates to a sucker rod wear-resistant alloy protective pipe connector with guiding function. Background technique [0002] At present, in the process of oil drilling, it is necessary to use sucker rods for crude oil transportation. At present, anti-eccentric wear couplings and sucker rod centralizers are generally used in the existing technology. Sucker rod centralizers are used for damage and wear: "dogleg degree": ≥3° / 25m, two whipping points are connected at the front and rear: more than 2 centralizers, and the sucker rod is used to stabilize below the whipping point; There are more than 2 centralizers above the rod, and one centralizer is connected to each near the distance of 25 m and 45 m from the wellhead. The effective spacing is 3.2m, and the effective anti-wear spacing in the longitudinal direction of the coupling is 1.6m. The anti-wear degree of the coupling is more than twice that of the rod body, but the structure is comple...

[0002] At present, in the process of oil drilling, it is necessary to use sucker rods for crude oil transportation. At present, anti-eccentric wear couplings and sucker rod centralizers are generally used in the existing technology. Sucker rod centralizers are used for damage and wear: "dogleg degree": ≥3° / 25m, two whipping points are connected at the front and rear: more than 2 centralizers, and the sucker rod is used to stabilize below the whipping point; There are more than 2 centralizers above the rod, and one centralizer is connected to each near the distance of 25 m and 45 m from the wellhead. The effective spacing is 3.2m, and the effective anti-wear spacing in the longitudinal direction of the coupling is 1.6m. The anti-wear degree of the coupling is more than twice that of the rod body, but the structure is complex and the cost of use is high.
