Understanding the water intrusion patterns in carbonate reservoirs poses significant challenges, complicating the scientific management of water-producing gas wells, and assessing the impact of interlayer development on water intrusion is difficult. Focusing on the Changxing Formation gas reservoir lower structural aquifer in Yuanba, this study classifies water-producing wells into three types: non-interlayer type, semi-permeable interlayer type, and semi-sealed interlayer type, based on permeability differences and water production dynamics. By integrating material balance for waterdriven gas reservoirs and numerical simulation methods, differential allocation schemes for typical water-producing wells were simulated across three stages: elastic gas drive, water body replenishment, and simultaneous gas-water production. Combining experimental, dynamic analysis, and numerical simulation results, strategies for water intrusion control are proposed. Results indicate that for non-interlayer type gas wells, attention should be paid to the relationship between water cone velocity and production allocation during the elastic gas drive stage. Semi-permeable interlayer type gas wells need to identify the critical allocation for water cone breakthrough. Semi-sealed interlayer type gas wells need to determine the critical allocation for water cone bypassing the interlayer. In the simultaneous gas-water production stage, all three types of interlayer gas wells benefit from identifying the “productionintrusion balance” point to enhance recovery efficiency. This study is of significant importance for water control and mitigation in carbonate gas reservoirs with interlayers, providing theoretical references and technical guidance for the exploration and development of gas reservoirs of the same nature.
