Optimization and Performance Evaluation of Foam Discharge Agent for Deep Aquatic Condensate Gas Well

The block deep condensate gas reservoir in the basin southeast of South China Sea is a bottom water and producing late effusion, which faces problems such as scaling, oil–water two-phase flow, low temperature at subsea wellhead. mud line for this kind gas-well has characteristics including high content temperature, downhole injection with foam discharge agent scale inhibitor. In article, influence inhibitor considered first time, dynamic liquid-carrying experiment optimization performance evaluation agents was carried out according to these characteristics. experimental results show that optimized agent, ZHY-01, good resistance oil, optimal concentration recommended be 0.25%. Under concentration, capacity decreases slightly by 10.17% temperature. MA/AA reduced 11.86%, PESA 10.17%. research article have certain reference significance chemical screening drainage production process deep-water wells.
