摘　　要：子洲气田山2致密砂岩气藏气水分布复杂,气井产出的地层水按不同来源类型可划分为边(底)水、气层残留地层水、透镜体水3种,利用试气、测井和生产动态等资料对子洲气田生产井出水类型及机理进行研究,深入分析了其成因及识别特征。结合地质背景分析认为,作为典型的岩性气藏,子洲气田山2气藏水体分布主要受砂体分布、构造、储层物性变化和天然气运移成藏过程等因素影响,宏观上存在3大类气水分布模式。在地层水类型和水体分布模式研究的基础上,对子洲气田各类水体的纵、横向分布特征进行了描述。In Zizhou gasfield, Shan2 tight sandstone reservoir is characterized by complicated gas and water distribution. And formation water yielded can be divided into three types according to its source, containing edge(bottom)water, residual formation water,and lense water. For the yielded water, the type, mechanism, origin,and features were analyzed from gas testing, well logging, and production performance data. After a geological setting analysis, it deemed that, for Shan2 reservoir as a typical lithological gas reservoir, its waterbody is affected by some factors, including sandbody distribution, structure, physical property of reservoir, and gas migration and accumulation. Macroscopically, there are three types of gas and water distribution patterns. In addition, the lateral and vertical distribution of various waterbody in the gasfield is also illustrated on basis of formation-water type and waterbody distribution pattern.
