Abstract

The invention relates to oil production equipment, in particular to an environment-friendly paraffin-scale preventive viscosity reducer for underground oil pumping, comprising a jet flow ultrasonator, an ultrasonic cavitation cavity and a cyclone. The viscosity reducer is characterized in that: the cyclone is an inlet end; the back end of the cyclone is butted against a jet flow ultrasonic signal emitter and then is butted orderly against the jet flow ultrasonator and the ultrasonic cavitation cavity; and the outer end of the ultrasonic cavitation cavity is an outlet. The viscosity reducer solves the problem that the prior similar products are not ideal in the effects of preventing paraffin and reducing viscosity, really has ultrastrong functions of preventing paraffin, reducing viscosity and preventing scale, greatly increases the liquidity of crude oil, raises pump efficiency, increases oil well yield, needs no additional power, is safe and environment-friendly, accords with oil production wells with different types, and is suitable for the oil wells with different paraffin content and water content as well.

Description

(1) Technical field: [0001] The invention relates to oil exploitation equipment, which is an environment-friendly anti-wax, anti-scaling and viscosity-reducing device for underground oil pumping. (two) background technology: [0002] In the existing oilfields in my country, more than 80% of oil wells contain medium and high waxy oil with a waxy ratio of 10-40%. High waxy content will increase the viscosity of crude oil, reduce fluidity, and it is easy to condense and accumulate, thus causing oil production. Scaling and clogging of the screen and the upper and lower parts of the oil well pump will increase the useless power consumption of the oil well pump, reduce the oil output, and even completely block the wellbore and stop production. [0003] In order to solve the common problem of crude oil paraffin crystallization plugging wells, which is a common problem in oil production and production in oilfields, anti-wax and viscosity-reducing products have emerged in recent years...
