Abstract

The invention belongs to the field of hollow rods, particularly relates to a hollow rod watering viscosity reduction device, and aims to solve the problems that the viscosity reduction efficiency is reduced due to non-uniform water temperature caused by inconvenience in keeping constant temperature of hot water in the using process of an existing hollow rod watering viscosity reduction device, and the hollow rod is easy to block due to inconvenience in preventing backflow of crude oil. According to the scheme, the device comprises a hollow rod body, one end of the hollow rod body is fixedly connected with a water inlet through welding, a first empty groove is formed in the hollow rod body, a first through hole is formed in the inner wall of the hollow rod body, the first through hole is communicated with the first empty groove, and a first rotating shaft is rotationally installed in the first through hole; in the using process, the constant temperature of hot water can be conveniently kept, the viscosity reduction efficiency can be prevented from being reduced due to uneven water temperature, crude oil backflow can be conveniently prevented, the hollow rod can be prevented from being blocked, the structure is simple, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of hollow rods, in particular to a hollow rod water-mixed viscosity reducing device. Background technique [0002] An oil field refers to the sum of oil and gas reservoirs in the same oil and gas production area under the control of a single geological structure (or formation) factor; an oil well is a hole drilled for oil production and a well layout system according to the oil field development plan, and oil rises from the bottom of the well to Wellhead channel. In the production process of heavy oil wells in oil fields, some oil wells have high wax content, which is easy to precipitate and adhere to the inner wall of the oil pipe or the sucker rod on the upper part of the oil sucker pipe, causing channel blockage, and the downward movement of the sucker rod is blocked, so the wax has to be removed regularly. At present, wax removal generally adopts injecting hot water into the hollow sucker rod for viscos...
