Abstract
Gas well foam drainage gas extraction technology is an important measure to extend the stable production of gas wells,and the foam drainage agent is the core and key of the foam drainage gas extrac-tion technology.Through domestic and foreign literature research,we analyzed the mechanism and classifi-cation of foam drainage agents,introduced the research progress of new and efficient foam drainage agents for natural gas wells,such as condensate-resistant,high-mineralization-resistant,temperature-resistant,nano-particle-type,self-generated energy-type,intelligent response-type,corrosion-resistant,and analyzed the development idea,application and application effect of each type of foam drainage agent,and put for-ward the development trend of the new type of foam drainage agent for natural gas wells in the future.
