本文在研究了我国不同含油气盆地中几个不同地质时代、不同沉积体系、不同类型碎屑岩沉积体的沉积成岩特征以及与油气关系的基础上,提出了沉积体系及其分类的新概念,建立了沉积成岩结构框架,从中获取了成岩变量,旨在揭示碎屑岩沉积体之间的成岩序列、成岩矿物共生组合、成岩相、成岩旋回、孔隙消长与油气关系等方面的共存规律,阐明了成岩作用在区域分布上的时空性。它对深化、提高成岩作用研究和油气预测,将产生一定的影响。

Based on the study made on the sedi-diagenetic characteristics of clastic sedimentary rock bodies with different types,sedimentary system and geological ages from different oil-gas bearing basins in the country,the authors proposed some new concepts about sedimentary systems and their classification,established the structural framework of sedi-dia-genesis,therefrom obtained diagenetic variables which reveal the paragenetic lows for the diagenetic sequences between clastic sedimentary rock bodies,paragenetic association of diagenetic minerals,and diagenetic facies and circles,and porosity decreasing or increasing,and their relationship with oil and gas.The study will effect to certain extent on improving the research of diagenesis and oil/gas prediction.
