Problems solved by technology

However, most of the various improved wellhead centralizers are used to consider the issue of pipe fittings from the horizontal direction perpendicular to the wellhead. Wellhead pipes are less considered in the horizontal direction, and the centralization often cannot quickly achieve the desired effect, which makes the centralization efficiency low and time-consuming. strenuous, work fatigue

Abstract

The invention discloses a double-centralization wellhead pipe fitting device which comprises a main mounting plate, an auxiliary mounting plate, a motor, a power expansion device, a centralization arm, a centralization ring and a dovetail sliding plate. The main mounting plate and the motor are perpendicularly fixed onto the auxiliary mounting plate and are connected with each other, the middle of the main mounting plate is connected with one end of the centralization arm, the other end of the centralization arm is connected with the centralization ring, and the right side of the auxiliary mounting plate is connected with the power expansion device. The double-centralization wellhead pipe fitting device has the advantages that a wellhead pipe fitting can be centralized in perpendicular and horizontal directions, so that the wellhead pipe fitting can be centralized three-dimensionally, and purposes of comprehensive centralization and well drilling can be achieved.

Description

technical field [0001] The invention relates to a straightening device, in particular to a double straightening wellhead pipe fitting device. Background technique [0002] In the process of oil production in my country, the phenomenon of eccentric wear of oil well polished rods is relatively serious, and eccentric wear of polished rods and other pipe fittings will cause crude oil leakage and cause large-scale pollution. Therefore, people often use various improved wellhead centralizers to straighten oil well pipes to prevent the above problems produce. However, most of the various improved wellhead centralizers are used to consider the issue of pipe centralization from the horizontal direction perpendicular to the wellhead, and less attention is paid to the centralization of wellhead pipes in the horizontal direction, and the centralization often cannot quickly achieve the desired effect, which makes the centralization efficiency low and time-consuming Strenuous, causing wor...
