Sucker rod self-adaptive shaft paraffin removal device

Abstract

The invention relates to the technical field of oilfield exploitation equipment, and discloses a sucker rod self-adaptive shaft paraffin removal device. The sucker rod self-adaptive shaft paraffin removal device comprises a shaft, L-shaped supporting rods are arranged on the left side and the right side of the top of the shaft, a sleeve is jointly inserted into the opposite ends of the horizontal parts of the two L-shaped supporting rods, a fixing mechanism is arranged between the pipe wall of the sleeve and the horizontal parts of the L-shaped supporting rods, clamping mechanisms connected with the top of the shaft are arranged at the lower ends of the vertical parts of the two L-shaped supporting rods, a hydraulic cylinder is fixedly arranged at the center of the lower side of the pipe wall of the sleeve, a U-shaped connecting plate is fixedly arranged at the tail end of a piston rod of the hydraulic cylinder, fixing plates are fixedly arranged at the two ends of the U-shaped connecting plate, two fixing rods are symmetrically and fixedly arranged on the lower surface of each fixing plate, and a bearing seat is fixedly connected between the two fixing rods. The sucker rod self-adaptive shaft paraffin removal device can comprehensively remove paraffin on the inner wall of the shaft, can meet the requirement for removing paraffin in shafts with different diameters, and improves the paraffin removal efficiency.

Description

technical field [0001] The invention relates to the technical field of oilfield exploitation equipment, in particular to a sucker rod self-adaptive wellbore wax removal device. Background technique [0002] Most of the crude oil produced in my country's oilfields is waxy crude oil. According to statistics, crude oil with a wax content higher than 10% accounts for about 90% of the country's total crude oil output. Crude oil, especially waxy crude oil, is a complex multi-component mixture. Under normal temperature and pressure, it is a colloidal suspension system in which gas, liquid and solid phases coexist. When the concentration of the dispersed phase (or gel) in crude oil increases, the rheological behavior of crude oil will be abnormal, that is, it will show non-Newtonian characteristics. Rheology is a new frontier discipline developed in modern times. The research object It is a material with complex mechanical characteristics. Crude oil, especially waxy crude oil, i...
