Problems solved by technology

In order to obtain microbubbles with smaller diameters, the diameter of the generated bubbles can be controlled by further ultrasonic oscillation, which can reach a range of 1 to 50 microns, but this technology is still in the laboratory research and development stage, and its gas production capacity is far from reaching requirements for industrial applications

Abstract

An embodiment of the invention discloses an ultrasonic microbubble generation method, device and system. The device comprises a horn-shaped conductor, wherein the horn-shaped conductor comprises an upper horn-shaped body and a lower cylindrical body; the horn-shaped body is provided with a cavity with an opening in the upper part, a microporous vibration chip is fixedly connected with the upper end of the cavity, a micropore array of the microporous vibration chip corresponds to the opening in the upper part of the cavity, and a through hole allowing outside air to enter the cavity is formed in the upper side wall of the cavity; energy transition rings and electrode slices are arranged on the cylindrical body, the outer side of the cylindrical body is subjected to insulated enclosure, andconnecting wires of the electrode slices are led out through steel tubes and connected with an external ultrasonic oscillation controller. With the adoption of the device, the production quantity of the microbubbles can be substantially increased, and the device is safer and more efficient.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploration and development, in particular to a method, device and system for generating ultrasonic microbubbles. Background technique [0002] Microbubble generation technology is gradually emerging in the field of greenhouse gas environmental protection and oil displacement technology development. In the field of petroleum development, the whole formed by dispersing micron-sized bubbles in the water phase is called the water-gas dispersion system. During oil displacement, tiny air bubbles can enter pores where injected water is difficult to enter, thereby improving sweep efficiency and improving recovery. Micron-sized bubbles are easy to expand in larger pores, which can block large pores and divert liquid to play a role in profile control. Oil flooding with water-gas dispersion system is an effective replacement method to continue to improve oil recovery in the later stage of water floodin...
