世界上有不少油气田的高产层是碳酸岩。它们属于碳酸盐台地边缘的生物礁相、浅滩相及其前缘的斜坡塌积相类型。因为台缘带是沉积环境的水动能高值带,其上的礁灰岩和内碎屑灰岩往往发育大量的原生孔隙,如生物骨架孔、粒(或砾)间孔和遮蔽孔等;台缘带又是构造变动的枢纽带,沉积物易遭暴露溶蚀和受力变形,也会产生如淋滤 Many high-yield formations in many oil and gas fields in the world are carbonate rocks. They belong to the carbonate platform margin of the reef facies, shallow facies and its front slope slope faulting phase. Because of the hydrodynamic high value zone of sedimentary environment, the margin reef limestone and inner clastic limestone often develop a large number of primary pores, such as biological skeleton holes, grain (or gravel) Taiwan is also a structural belt with changes in the hub, the sediments vulnerable to exposure and erosion by force deformation, can also produce, such as leaching
