摘要
通过分析孔滩气田茅口组气藏的地质特征和生产动态资料,提出了气藏裂缝圈闭系统的划分新观点。同时根据各裂缝圈闭系统的静、动态资料,分析了每个裂缝圈闭系统的地层水存储模式,认为该气藏存在4个裂缝圈闭系统,其中孔6井区裂缝圈闭系统为底部地层水存储模式,孔9井区裂缝圈闭系统为边部地层水存储模式,孔24井区和孔27井区裂缝圈闭系统为物性差异局部封存水存储模式。分析孔滩气田茅口组气藏水侵特征,为气藏的整体治水措施提供了可靠的依据。
Based on the geological characteristics and production dynamic data of Maokou Formation gas reservoir,Kongtan gasfield,a new idea classifying fracture trap systems has been put forward.Furthermore,according to the static and dynamic data,this paper analyzes the storage mode of formation water for each fracture trap system.Result shows that there exist four fracture trap systems in this reservoir,including: Kong 6 wellblock,with bottom formation-water storage mode;Kong 9 wellblock,with edge formation-water storage mode;Kong 24 and 27 wellblocks,having storage mode of partially connate-water with physical difference.Moreover,water-invasion property of the reservoir is analyzed,which provides a reliable basis for water control.
