Oil pumping rod anti-fouling device

Abstract

The invention provides an oil pumping rod anti-fouling device and relates to an oil pumping rod anti-fouling device for an oil well. The oil pumping rod anti-fouling device comprises a main body; a channel is formed at the center of the main body; two elastic rubber barrels are arranged inside the main body, are C-shaped and are in back-to-back connection with each other; a through hole is formed at the connecting center of the two elastic rubber barrels, and a center point of the through hole in a horizontal plane is superposed with that of the main body on the same horizontal plane; and the two elastic rubber barrels are hermetically connected with an oil pumping rod.

Description

technical field

[0001] The invention relates to an antifouling device for sucker rods used in oil wells. Background technique

[0002] During the process of lifting the sucker rod during the pump inspection operation, oil wells with high gas content blow out intermittently and the surface of the sucker rod raised from the wellhead carries crude oil, which is scattered on the derrick, pumping unit and wellhead operators, causing pollution. Domestic anti-fouling devices, such as wellhead mechanical wax removal devices, can only be applied to vertical wells, and cannot be used on sucker rods equipped with centralizers in directional wells, which cannot effectively solve the above pollution problems, and are affected by rivers, lakes, fish ponds, Affected by many ground conditions such as farmland and villages, there are many directional inclined wells in oil wells, so the problem of anti-fouling needs to be solved urgently.
