摘要

摘要: 兰坪坳陷的油气主要见于金顶矿区的下含矿层,储层主要为上三叠统三合洞组的灰岩和角砾状灰岩。油气地球化学特征表明有机母源输入是多源的,沉积成烃水体介质以还原性占优势,具有较高盐度,有机质热演化处于成熟—高成熟阶段,生物降解改造较为强烈。根据原油的母源贡献、生物降解、环境介质条件等特征,将兰坪坳陷原油划分为3类组群。

Abstract: Oil were recently discovered in brecciated limestone,micrite kimestone and dolomitized limestone a ssociated with Jinding lead-zinc deposits. The geochemical characteristics indicate that sourceinputs were multiple. The sedimentary water medium was reducing with high salinity. Thermal evolution is in the stage of mature to high mature cha racterized by highly biodeg radation. Based on the source contributions, biodeg radation modification and environmental medium,three petroleum families were classified.
