一、我国碳酸盐岩油气的分布我国海相碳酸盐岩广泛发育于古生代地层之中,南方中生代的三迭纪地层也普遍发育碳酸盐岩,其余中新生代地层中的碳酸盐岩除南海海域外,仅以夹层或湖相介壳灰岩的形式存在。经二十余年的油气田调查和勘探工作,在我国碳酸盐岩广泛发育的四川盆地和华北大型 First, the distribution of carbonate rocks in our country Marine carbonate rocks are widely developed in the Paleozoic strata, the Southern Mesozoic Triassic strata also generally develop carbonate rocks, and the remaining Mesozoic carbonate Except for the South China Sea, rocks are only in the form of intercalated limestone or intercalated limestone. After more than 20 years of oil and gas field investigation and exploration work, extensively developed carbonate rocks in China in Sichuan Basin and North China large
