摘　　要：四川盆地安岳气田上三叠统须二段气藏动态监测资料少,气藏连通性不清楚,治水措施多样,效果参差不齐。以气藏地质为基础,结合生产动态资料,深入分析气藏井间连通关系,认为气藏以独立的单井压力系统为主,井间基本不连通;气藏气水关系复杂,地层水侵方式以裂缝水窜为主,生产受水影响严重,但水体能量小。在此基础上综合排水工艺的适用条件,提出气藏应实施单井排水的治水思路及不同产水特征下的治水工艺措施。该研究成果对安岳气田须二段气藏治水有较好的指导作用,建议措施已在生产现场应用。For the Upper Triassic Xujiahe 2(T_3x^2)reservoir of Anyue gasfield in Sichuan Basin, the results of various measures against water control were less than satisfactory due to the lack of dynamic monitoring data and uncertain reservoir connectivity. Based on the geological characteristics, integrating prod uction performance data and inter-well connection, we consider that this reservoir, without inter-well connectivity, is dominated by independent pressure system of single well; and under the condition of complicated gas-water relation, its water invasion is dominated by fracture water channeling, seriously impacting the production with low energy of water body. Therefore, according to the application of drainage technology, we suggest implementing single-well drainage, and put forward water-control technologies for different water-producing properties. Field application shows that this study provides a good guidance for water control.
