Multifunctional processor for liquid generated underground

Abstract

The invention relates to petroleum extraction equipment which is a multifunctional processor for liquid generated underground. The processor is provided with a pipe barrel, and the tail end of the pipe barrel is provided with a check valve. The processor is characterized in that the pipe barrel is internally provided with a first-order grid type sound generator, an impinging nozzle atomizer, a second-order grid type sound generator and a first-order turbine mixed-phase device sequentially. The processor overcomes the defects that the prior products of the same class adopt magnets to prevent waxes and reduce the viscosity so as to be easy for adsorbing ferromagnetic substances to block wells; and a single-plate plate spring sound generator has small oscillation amplitude and sound intensity and quick weakening so as to influence the effects of preventing the waxes and reducing the viscosity. The processor has the ultrastrong functions of preventing the waxes and reducing the viscosity, improves the liquidity of crude oil and the pump effectiveness, has safety and environmental protection, and not only conforms to different types of the oil extraction wells, but also is suitable for the oil wells of different wax contents and water contents.

Description

(1) Technical field: [0001] The invention relates to oil exploitation equipment, which is a multifunctional downhole liquid production processor used for downhole oil pumping. (2) Background technology: [0002] In the existing oilfields in my country, more than 80% of the oil wells with a crude wax content of 10-40% are medium and high wax-containing oil wells. The high wax content increases the viscosity of the crude oil, reduces the fluidity, and is easy to condense and accumulate, thereby causing oil production. The screen tube and the upper and lower parts of the oil well pump are fouled and blocked, which increases the useless power consumption of the oil well pump, reduces the oil output, and even completely blocks the wellbore and stops production. [0003] In order to solve the common problem of oil production and production in oil fields, the paraffin crystallization and blocking of crude oil, anti-wax and viscosity-reducing products have emerged in recent years.
