AI Technical Summary
In the existing natural gas extraction process, the sand removal and separation system has problems such as large sand removal workload, high labor intensity, easy equipment wear, low sand removal efficiency, complicated operation, large equipment footprint, high investment, and environmental pollution. Especially in hydraulic sand fracturing technology, the wellhead pressure is high and the formation sand production is serious, which affects the safety of the gathering and transportation system.
A miniaturized, integrated, and intelligent sand and liquid separation device is adopted, which combines cyclone separation, gravity separation, and blade defoaming technology. The equipment structure is optimized through modular design and CFD flow field simulation to achieve gas-liquid separation and sand and gravel separation. The separation efficiency is optimized by using an adaptive drainage and production control system.
It improves sand removal efficiency, reduces the labor intensity of manual sand removal due to low operational flexibility, extends equipment service life, reduces floor space and investment, and enhances the safety and intelligence level of the collection and transportation system.
