摘　　要：在异常高压有水气藏开采过程中,气藏水窜是产能持续大幅度下降、水淹井不断增加、单井动态控制储量急剧减少的主要原因,严重影响该类气藏的最终开发效果,因此气藏实施整体治水已成为开发生产的指导方向。在系统分析河坝飞三有水气藏开采现状、水侵特征的基础上,建立数值模拟模型,针对气藏可能的水侵特征,结合井区实际见水情况,在研究小油管携液、井口增压携液基础上,总结出河坝异常高压有水气藏的治水措施。研究结果为提高河坝飞三有水气藏最终采收率提供了理论依据。In the process of producing water-bearing gas reservoirs with abnormal pressure,water channeling is the major reason for drastic production decline,increase of watered-out wells,and fast reduction of reserves controlled by single well,therefore integral water control has become a guiding policy for developing such reservoirs. Production status and water invasion features of Heba Feisan water-bearing gas reservoir have been systematically analyzed,on which basis a numerical simulation model has been established. Based on potential water invasion behavior and actual water breakthrough situations,water control measures are proposed for the water-bearing gas reservoir with abnormal pressure in the Heba area in conjunction with fluid-carrying with small-size tubing and boosting pressure at wellhead. The research results provide theoretical basis for improving the ultimate recovery of Heba Feisan gas reservoir.
