Abstract
The present disclosure provides a microbubble generation device and equipment, wherein the microbubble generation device comprises: a microbubble generation mechanism having a housing and a core tube provided to pass therethrough, wherein at least one filter plate is provided on a peripheral sidewall of the housing, and an annular space is formed between the housing and the core tube; a flow rate control mechanism provided in the annular space, and connected to the core tube that is communicated with the annular space through the flow rate control mechanism, wherein a blocking ball is provided in the flow rate control mechanism and capable of blocking the flow rate control mechanism in a state that a pressure of gas injected into the flow rate control mechanism decreases; and a pressure balancing mechanism provided outside the housing and having a pressure balancing tube and a fluid check valve connected thereto. The present disclosure can withstand a huge pressure difference during a movement within a wellbore from a ground surface to an oil reservoir and take preventive measures for the failure. The gas injection process of the present disclosure not only meets the microbubble vo…
