摘要

烃源岩是含油气系统和油气成藏的基础, 国内外油气地质学家对其进行了多方

面的研究。目前烃源岩排烃研究已取得了很大进展, 但也存在着较多的问题。排烃门限理论

能够很好地解决烃源岩的排烃问题, 根据此理论可以定量计算排烃量, 并对其排烃模型进行了

修正。排烃门限理论目前已被用来判别油气源岩、综合定量评价源岩、研究油气运聚机理与成

藏模式。

Abstract

H ydrocarbon source rock is the foundation of pe tro leum
system and hydrocarbon accumu lation, and the dom estic and
internationa l o il g eo log ists have carr ied on a var ious research.
The studies o f hydrocarbon expulsion of sou rce rock hav e
m ade a g reat progress, but som e prob lems still ex ist
currently. This thesis elabo rates prob lem s m entioned in
form er theor ies. It has been proved that the hydrocarbon
expu lsion thresho ld theory can w e ll resolve hydrocarbon
expu lsion problem s of source rock, and w e can ca lcu la te
quantificationa lly the hydrocarbon expu lsion quantity.
Furthe rmo re, the hydrocarbon expu lsion mode l is m od ified. So
far the hydrocarbon expu ls ion thresho ld theory have a lready
been used to d istingu ish the source rock, evalua te
quantitative ly sou rce rock, and study pe tro leum m ig ra tion
m echan ism and reservo ir form ing mode.l
