摘　　要：中国海相沉积分布广泛,古老碳酸盐岩是勘探规模储量发现的主要领域,在四川盆地的震旦系与寒武系、塔里木盆地的寒武系与奥陶系以及鄂尔多斯盆地的奥陶系均发现了规模储量。古老碳酸盐岩油气资源丰富,泥质烃源岩生烃潜力大,古隆起背景上油藏类型多,未来的油气勘探要集中在大型古隆起复式油气聚集带、区域不整合面控制的地层溶蚀带、台缘带礁滩体及与蒸发岩共生的台内颗粒滩等重点领域。四川盆地广泛分布的海相黑色页岩沉积是页岩气勘探的重要领域,非常规油气勘探前景广阔。Marine sediment developed widely in China, and ancient carbonate rock is the main exploration field for large-scale reservoir. Large-scale reservoir reserves were found in the Sinian and Cambrian in Sichuan Basin, in the Cambrian and Ordovieian in Tarim Basin and in the Ordovician in Ordos Basin. The ancient carbonate rock is characterized by abundant oil and gas resources, great hydrocarbon generation potential of argillaceous source rocks and various reservoir types in palaeohigh. Oil and gas exploration in the future should be concentrated in the multiple oil and gas accumulation belt in large-scale paleohigh, formation dissolution belt controlled by regional unconformity, reef flat in platform margin and particle beach symbiotic with evaporate. Marine black shale sediment widely developed in Sichuan Basin is an important field for shale gas exploration, and there are great prospects of unconventional oil and gas exploration.
