Product Advantages
① High displacement, wide range, from 30m³ to 3500m³ per day;
② High lift, with a maximum lift of up to 4000 meters;
③ Easy maintenance, convenient production adjustment;
④ Simple surface equipment, safe, and environmentally friendly;
⑤ Long pump inspection cycles, saving operational costs;
⑥ High system efficiency compared to other equipment for deep wells.
Product Applications
The electric submersible pump oil recovery system is mainly used in high-displacement, high-water-cut wells, primarily in Changqing Oilfield, Xinjiang Oilfield, and Jianghan Oilfield. Since 2020, over 30 units have been deployed, with 2 units applied for coalbed methane and 4 units for shale gas.
