摘要
低渗透储层的勘探和开发在我国非常重要,以沉积岩石学、储层地质学、测井地质学、石油天然气地质学等理论为基础,明确龙尾峁油区总体为一区域性西倾大单斜,长2～长6油层组高程依次降低,形态继承性较强.长2主要为曲流河环境,长4＋5、长6主要为曲流河三角洲环境,细分为三角洲平原、三角洲前缘两个亚相,前三角洲不发育.
The exploration and exploitation of low permeability reservoirs is very important in china.The longweimao oilfield is identified as regional west-inclined monoclinal based on sedimentary petrology,reservoir,logging,oil&gas geology.The structures of Chang 2-6 reservoirs are similar in successive order.The Chang 2 reservoir is formed in meandering river environment,the Chang 4+5 and Chang 6 reservoir formed in meandering river delta environment that can be subdivided into delta plain,two sub-phases of delta front and ingrowth of prodelta.
