Xushen gas field mainly exploits volcanic reservoirs of Yingcheng Formation. The gas reservoir type is mainly the bottom water gas reservoir. The number of water wells and water production are increasing year by year, which affects the development effect of the gas field. In view of the increasingly severe situation of water invasion and water production in gas fields, water invasion evaluation and comprehensive water control of gas reservoirs have been carried out, and a three-level evaluation process of water invasion qualitative identification, water invasion quantitative evaluation and water invasion impact quantitative evaluation has been formed. Based on the results of water invasion evaluation, combined with the characteristics of gas reservoir connectivity, structure, gas-water distribution, and water production, the three-level evaluation process has been formed. The integrated water control mode of the block (volcanic body) and single well water control mode by classification have been applied in each block, and good results have been achieved, which effectively supports the rational development and long-term stable production of bottom water gas reservoirs in Xushen gas field.
