摘　　要：根据录井、钻井、测井和试气等资料,开展杭锦旗地区南部气藏的流体类型识别和气水分布特征研究,探讨气水分布关系成因,建立适合杭锦旗地区的含气指示曲线和不同类型流体的识别标准,对主要含气层段——下石盒子组气藏进行精细解剖,分析气层、水层的纵向和平面分布特征。结果表明:杭锦旗地区气水关系较为复杂,主要表现为没有统一的气水界面,不同构造位置、不同河道微相气水关系不同,烃源岩分布和油气运移通道决定气层的分布规律,气水的差异聚集和构造运动引起气水二次分异,造成杭锦旗地区的气水分布的复杂性。Based on the data of mud logging,drilling,logging and testing,the fluid type identification of gas reservoirs and the distribution of gas and water in the south of Hangjinqi Area is studied.The causes of the relationship between gas and water distribution are discussed in this paper.First,this paper establishes gas-bearing indicator curves and identification criteria for different types of fluids in Hangjinqi Area.Second,the main gas-bearing segment lower Xiashihezi Formation gas reservoir is carefully dissected and the vertical and horizontal distribution characteristics of gas and water layers are analyzed in this paper.The results show that there is no uniform gas water interface,the relationship between gas and water is very comlicated in different structures and different channel microfacies.The regularities of distribution of gas and water is not clear.According to the reservoir condition,it is concluded that the distribution of hydrocarbon source rocks and the migration channels of oil and gas determined the distribution of gas reservoirs,and the differential accumulation of gas and water and tectonic movement caused the two differentiations of the two fluids.They cause the complexity of gas and water distribution in Hangjinqi Area.
