摘　　要：裂缝型底水气藏裂缝较为发育,储层非均质性强,气井普遍产水且形式较为复杂,为明确该类型气藏的水侵规律,准确预测气井的见水时间,以C气田Y层组裂缝型底水气藏为例,根据出水井的水侵特征及裂缝发育情况,总结出产水井的水侵模式,然后采用统计学方法,利用部分油藏地质参数,建立裂缝厚度、单井产量与气井出水时间的非线性关系,绘制裂缝型底水气藏气井产水时间的预测图版,从而预测气井在不同配产下的见水时间。该研究可为同类型气藏的合理开发提供一定的指导。Fractured gas reservoir with bottom-aquifer is characterized by relatively developed fractures,strong reservoir heterogeneity,and general and complicated water productions in gas wells. A fractured gas reservoir with bottom-aquifer of Layer Y in C gasfield is researched to identify the water invasion performance and accurately predict the water breakthrough time. The water invasion modes are summarized according to the water invasion performances and fracture development of gas wells with water production. Based on part of reservoir geological parameters,a statistical approach is used to establish a non- linear relationship between fracture thickness,single- well production and water breakthrough time. A prediction chart of water breakthrough time for fractured gas reservoir with bottom-aquifer is prepared to predict the water breakthrough times of gas wells under different production allocations. This research could provide certain guidance for the efficient development of fractured gas reservoir with bottom-aquifer.
