Advantages of screw pump for liquid extraction and discharge

At present, the exploration of Shengli Oilfield has entered the late stage, and the exploration and oil testing of marginal boundaries and poor oil quality layers are gradually increasing, especially for some target layers that are soft and prone to sand production, or crude oil with high specific gravity and viscosity. Therefore, there is a lot of research on drainage technology for such production layers. Screw pump drainage is a highly applicable and economical drainage production process.
