Abstract: As the development of water-producing gasfield continues, the number of the wells with water breakthrough increases quickly, leading to significant decline of gas production, which brings severe challenges to stable gasfield production and national stable gas supply. As the main technologies for solving the water breakthrough of gas wells and guaranteeing the stable production of gasfields, the drainage gas recovery technologies are facing a series of new challenges, which gradually increases the field inadaptability of existing drainage gas recovery technologies. The status and technical bottlenecks of drainage gas recovery are not understood clearly, so the research direction cannot be defined, so as to restrict its further improvement and development. To solve this problem, the gasfields that have been developed in China were analyzed systematically, the roles and positions of drainage gas recovery technologies in the process of gasfield development were discussed, and domestic and foreign research progress of drainage gas recovery in recent years was illustrated. Then, the problems existing in the field were analyzed, and three major challenges to the drainage gas recovery in China in the current stage were pointed out. Finally, based on the research status and difficulties of domestic and foreign drainage gas recovery technologies, 6 research directions for the development of drainage gas recovery technologies in the future were put forward. The research results have guiding significance for the development of drainage gas production technology.
