摘要： 东海西湖凹陷已开发的气藏以水驱气藏为主，大部分气井投产后2~3年开始出水，产量递减快，因此，正确认识边底水气藏的出水规律及控制因素，是成功开发该类气藏的关键。以西湖凹陷生产动态数据为基础，利用产水特征参数判别法和不稳定试井水侵识别法研究了气井的产水特征及水气比上升规律，形成了水驱气藏早期水侵综合识别方法，明确了不同类型水驱气藏的含水上升规律及主控因素。依据气井无水采气期长短及含水上升规律，可将水驱气藏产水特征曲线归结为3种类型，分别为尖峰状竖型、梯状台阶型、凹状缓慢型，其中尖峰状竖型主要受水体大小影响，以强边水气藏为主；梯状台阶型主要受隔夹层发育程度及韵律特征影响，以隔夹层不发育的底水气藏为主；凹状缓慢型主要受储层及水体大小影响，以弱水驱气藏为主。水驱气藏出水规律及控制因素的研究，为水驱气藏开发技术政策的制定奠定了基础。

Abstract: The water drive gas reservoirs are principal types in Xihu Sag, in which most of wells produce water after several production years, so a correct understanding of the effluent characteristics and controlling factors of edge and bottom water reservoir is the key to the successful development of the gas reservoirs. Based on the production dynamic data, dynamic production water invasion identification method and unstable test water invasion identification method were used to study the water production characteristics and water gas ratio rising law, and the law of water cut rising and main controlling factors of different types of water drive gas reservoirs were defined. The results show that the water production characteristic curves were classified into three types,which are vertical spike type, ladder step type and concave slow type. The vertical spike type is mainly controlled by the size of water,which is dominated by strong edge water gas reservoir. The ladder step type is mainly controlled by the development degree and rhythm characteristics of interlayer,which is dominated by bottom water gas reservoirs. The concave slow type is mainly controlled by reservoir and the size of the water,which is dominated by weak water flooding gas reservoirs. This study result is helpful for the technical policy of further development of water drive gas reservoir.
