Embodiment 1

[0010] The sucker rod antifouling device according to the present invention includes a device body 1, and an elastic rubber cylinder 2 is arranged inside the body 1. The elastic rubber cylinder 2 is a C-type rubber cylinder connected by two back-to-back types, and the connecting part of the two elastic rubber cylinders 2 There is a through hole in the center of the main body 1, and a through hole is also provided in the center of the main body 1. The two through holes overlap at the center point of the same horizontal plane. , the base is fixedly connected with the oil well, and the center of the base is correspondingly provided with a through hole, and the cross section of the connecting part of the two elastic rubber tubes 2 is larger than the maximum cross section of the centralizer.

[0011] When in use, when the sucker rod passes through the elastic rubber tube 2 during the process of lifting the sucker rod, the through hole of the elastic rubber tube 2 will hold the sucke...

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. Contents of the invention [0003] The invention ai...
