摘　　要：在对英吉苏凹陷基本地质条件、次生孔隙的形成、成岩序列分析及成岩演化阶段划分的基础上,建立了英吉苏凹陷天然气藏的成岩演化模式,研究了英吉苏凹陷天然气的成藏机理,建立了成藏模式.结果表明:英吉苏凹陷具备了形成大中型气藏的地质条件和成藏要素.研究结论对塔里木盆地气藏分布规律的研究以及寻找新的油气资源提供必要的依据.Based on the analyses of general geological conditions,secondary pore generation and diagenetic sequence,and the division of diagenetic evolution phase,the diagenetic evolution mode of the gas reservoir in Yingjisu Sag is established;the formation mechanism of the natural gas reservoir is studied and its formation mode is obtained.The study results show that,Yingjisu Sag possesses the geological conditions and elements of forming large-scale and medium-scale gas reservoirs,which has guiding effect to studying gas reservoir distribution and finding out new oil and gas resources in Tarim Basin.
