摘要
徐深气田火山岩气藏气井出水情况比较复杂。为搞清这类气藏气井的出水机理，以典型井x为例，在分析该井地质特征的基础上，应用单井模拟技术，对该井裂缝的大小和平面发育程度、采气速度及水体规模进行了模拟。结果表明：高角度缝是X井底水活动的主要通道；高角度缝大小和分布成为控制水窜的主要地质因素；采气速度是影响X井气藏出水大小的主要动态因素，以试采期间配产长期生产，预计气井出水的情况相对稳定；综合判断X井水体倍数约为1.10倍，水体大小对底水气藏开发效果有很大影响。
Water producing in gas wells in volcanic reservoirs in Xushen Gas Field is more complicated. In order to study water producing mechanism of gas wells, this paper takes Well X as an example to simulate size and areal development of fractures in this well, gas production rate and water body scale using techniques for single well simulation on the basis of analyzing geologic feature of this well. Results indicate that fractures with high angle are the main channels of bottom hole water movement in Well X; size and distribution of fractures with high angle are the main geo-factor to control water channelling, gas production rate is the main dynamic factor to affect the water producing rate of Well X,and it is expected that the situation of water producing will be relatively stable while keeping the allocation during a long term production ; through comprehensive judgment the multiple of water body of Well X is about 1.10 times, the size of water body has a strong effect on development of gas reservoirs with bottoml water.
