摘　　要：鄂西渝东地区建南构造飞三段经历了古油藏聚集、古油藏裂解与古气藏聚集、古气藏调整改造形成现今气藏三个阶段。结合前人研究成果和工区实际,确定研究区储层沥青含量、古孔隙度、古油层厚度、面积、古油藏及裂解气量的统计和计算方法。古油气藏计算结果表明,北部的古油藏裂解气足够为现今的气藏提供气源,同时可能还有尚未找到的地质储量,具有进一步勘探的潜力。Fei-3Member has gone through three stages：fossil oil reservoir accumulation,its splitting decomposition and fossil gas reservoir accumulation and its adjustment and reconstruction.Based on previous research results and real condition in the workzone,this paper presents the method for the research area to count up and calculate formation bitumen content,palaeo-porosity,palaeo-reservoir thickness and size and fossil oil reservoir as well as its split gas content.It is suggested that the lower limit of paleo-reservoir identification is 2.8% palaeo-porosity and1% bitumen content on the basis of correlation statistics of bitumen content with palaeo-porosity.
