Multi-stage composite rotational flow and turbulent flow sound wave super-strong viscosity reduction, paraffin control and oil increasing device

Abstract

The invention provides a multi-stage composite rotational flow and turbulent flow sound wave super-strong viscosity reduction, paraffin control and oil increasing device. The multi-stage composite rotational flow and turbulent flow sound wave super-strong viscosity reduction, paraffin control and oil increasing device comprises a pipe shell; an oil inlet is formed in the front end of the pipe shell; an oil outlet is formed in the rear end of the pipe shell; a layered rotational flow mechanism is mounted in the position, located behind the oil inlet, in the pipe shell and comprises an outer-layer rotational flow sleeve mounted on the inner wall of the pipe shell; a middle spacer sleeve is fixedly arranged on the inner wall of the outer-layer rotational flow sleeve; an inner-layer rotationalflow column core is arranged in the middle spacer sleeve; the middle spacer sleeve is used for separating an inner-layer oil passage from outer outer-layer oil passage; an atomizing nozzle is arranged in the position, located on the inner side of the oil outlet, in the pipe shell; a multi-stage turbulent flow mechanism is arranged at the outer end of the oil inlet in the pipe shell; a first-stageturbulent flow chamber is formed between the multi-stage turbulent flow mechanism and the layered rotational flow mechanism; a second-stage turbulent flow chamber is formed between the rear end of the middle spacer sleeve and the end part of the inner-layer rotational flow column core; and a third-stage turbulent flow chamber is formed between the layered rotational flow mechanism and the atomizing nozzle. According to the multi-stage composite rotational flow and turbulent flow sound wave super-strong viscosity reduction, paraffin control and oil increasing device, the paraffin control and viscosity reduction effects are greatly improved, the efficiency of an oil well pump is improved, an oil pipe almost cannot be blocked, and the yield of an oil well is increased.

Description

technical field [0001] The invention relates to the field of oil extraction equipment, in particular to a multi-stage compound swirling flow, turbulent flow sound wave super-strong viscosity-reducing, wax-reducing, wax-reducing and oil-increasing device. Background technique [0002] In the later stage of crude oil production, due to the low pressure and insufficient energy of the reservoir, the liquid production gradually decreases. In order to enhance oil recovery, the main components of the production fluid in crude oil production are water, crude oil, petroleum gas escaped from crude oil due to pressure reduction, and a small amount of other substances brought out with water and oil in the formation, of which water accounts for 60% -70% or more. Nowadays, it is mainly to inject high-pressure water from the ground into the underground oil layer or add chemical substances that can drive oil into the water, which is called water flooding or compound flooding. In this way, ...
