摘要

本文结合本区碳酸盐岩的热演化特征,研究了沉积有机质的热演化规律,明确地阐述了碳酸盐岩生油岩在不同的热演化阶段其有机碳含量的下限值.求出各类干酪根在不同的热演化阶段的H/C与R值的回归关系式,并研究了各类干酪根的油气演化界限,讨论了本区的油气勘探前景.

Abstract

Combined with the characteristics of the thermal evolution of carbonate rocks in the area, the paper studies the regularities of thermal evolution of sedimentary organic matter. Clear explanation of lower limit values for organic carbon contents in carbonate source rocks and of relations between H/C and Ro for kerogen at different stages of thermal evolution are given. In addition, the limits of petroliferous evolution of kerogen and exploration prospect are discussed.
