摘要
川东南地区震旦系白云岩具有良好的油气储集潜力。从岩石学、矿物学、阴极发光、地球化学等方面对遵义松林剖面震旦系灯影组岩溶特征进行综合识别。在此基础上,对准同生岩溶垂向发育特征进行综合分析,自下而上识别出3个大气成岩透镜体,并将单个透镜体划分为大气渗流带、大气潜流带及海底潜流带3个岩溶带。
In Southeast Sichuan,Sinian dolostone has favorable potential of oil/gas accumulation.Based on the subject of petrology,mineralogy,cathodoluminescence emission analysis,geochemical etc,comprehensive identification for characteristics of syngenesis palaeokarst of Sinian in songlin section have been conducted.By dividing the karst zones,the rule of vertical zoning of syngenesis palaeokarst has been analyzed.Three lenticles of atmogenic rock have been discriminated.A lenticle can be divided into three karst zones,which consists of atmogenic vadose zones,atmogenic underflow zones and submarine underflow zones.
