微生物碳酸盐岩油气储层研究现状与展望

微生物碳酸盐岩是一种重要的油气储集岩。在中国古老深埋碳酸盐岩地层中它们是主要的岩石类型。微生物碳酸盐岩通常可划分为叠层石、凝块石、树枝石、均一石和核形石等五种类型。储层孔隙系统与微生物岩的沉积结构和构造密切相关，窗格孔（洞）和格架孔（洞）是主要储集空间类型。全球中新元古界至中生界都发现了以微生物碳酸盐岩为储层的油气田，资源潜力巨大。 微生物岩储层的岩石类型、沉积构造、相序结构、沉积模式和储层有利相带尚有许多不明晰之处，是今后进一步深化研究的重点方向。

Review and Prospectives of Microbial Carbonate Reservoirs

Microbial carbonates are  important oil & gas reservoir rocks, as well as the main rock types in China old strata. Microbial carbonates can be divided into stromatolites, thrombolite，dendrolite and other two types. The reservoir pore systems are closely related to microbialite sedimentary process, and mostly affected by structures and textures of microbialites. Framework and fenestral vugs are the main types of reservoir space. From Middle-Neo Proterozoic to Mesozoic, microbial carbonates reservoirs are discovered globally in various oil & gas fields, so that their petroleum resource potential is great.The researches on rock types,litofacies texture, depositional models and favorable facies zones of microbial reservoir, are well worth deep study in future.
