STUDY AND APPLICATION OF THE THERMAL EFFECT OF DEEP PUMPING TECHNOLOGY FOR THE COMBINATION OF HYDRAULIC JET PUMP ANO ELECTRIC SUBMERSIBLE PUMP

The deep well artificial lift technology with high solidification point, high wax content and bad fluid supply capacity continues to be a problem for development technology in oilfield. The deep pumping technology system for the combination of hydraulic jet pump and electric submersible pump is a kind of good deep well artificial lift method because of its high thermal efficiency, great reliability and adaptability. This paper introduced the system and its thermal efficiency, set up the calculation model for the temperature distribution of fluid and provided the basis for the parameter design of the system. The temperature calculation is conformity with reality. The test showed that the artificial lift method had a better thermal recovery effect.
