The main principles for the development of water driven gas reservoirs are to identify water invasion phenomena as early as possible, develop reasonable work systems based on dynamic reserves, fully utilize the dry period for production, and thereby improve the recovery rate of gas reservoirs. This article takes the T gas reservoir in the middle of Block B on the right bank of the Amu Darya River as the research object, and explores the application of material balance method, production performance data analysis method, and well testing data analysis method in water invasion identification. Through argumentation, it is concluded that for weak water drive gas reservoirs with low water production, the production dynamic data analysis method is a more intuitive and rapid method for identifying water invasion. With the accumulation of production history, the material balance method and well testing data analysis method can be gradually adopted to determine the time and degree of water invasion. By applying these methods, water invasion phenomena can be more accurately identified, more effective development strategies can be formulated, and the recovery rate of water driven gas reservoirs can be improved, thereby achieving maximum utilization of resources and improving economic benefits.
