摘　　要：根据野外露头样品实验分析数据,分析了思茅盆地上二叠统羊八寨组富有机质页岩空间展布、有机地化特征、无机矿物组分和孔裂隙特征,考虑富有机质页岩TOC、Ro、厚度及埋深等因素,采用综合叠加法,预测了富有机质页岩有利区2处,作为下一步勘查研究重点方向。Based on the geochemical analysis data of the outcrop samples,analyzes of organic-rich shale space distribution,organic geochemical properties,inorganic mineral composition and pore system layout of the upper Permian Yangbazhai formation in Simao basin.Consideration for factors of organicrich shale′s TOC,Ro,thickness and depth,and using the method of superposition for comprehensive information,predicts two organic-rich shale favorabl areas as the focus of the next exploration and survey.
