The Dongping 1 block bedrock gas reservoir belongs to a structurally controlled bottom water block gas reservoir. The development characteristics of internal fractures in the bedrock are complex, the geological conditions are special, and the reservoir heterogeneity is strong. With the continuous deepening of gas field development, gas reservoir water invasion is severe, production capacity is decreasing rapidly, and the trend of gas reservoir water invasion has not been fundamentally controlled. This paper deepens geological understanding, analyzes the reservoir characteristics of Dongping block 1 gas reservoir, and determines that the gas reservoir has the characteristics of“plane partitioning and vertical zoning”. Using the water seal material balance method to calculate the water invasion parameters of a single well, the water invasion pattern of a gas reservoir is studied through a combination of dynamic and static methods. By combining water invasion pattern research with optimization of production processes, the overall water control direction of the gas reservoir is improved and adjusted. After adjustment, the daily drainage volume of the gas reservoir is significantly increased, weakening the water energy and bottom water invasion speed in the gas reservoir, and the water seal gas is released to varying degrees, realizing flowing production for partial shutdown gas wells and an increase in gas well production. The results provide guidance for the prevention, identification and control of water invasion of bedrock gas reservoir and provide reference for the development of similar bedrock gas reservoir in the later stage.
