| 摘 要： | 本文提出了烃源岩演化与生、排烃史综合模拟模型。该模型包括埋藏史模块、热史模块、成熟史模块、生烃史模块与排烃史模块５个组成部分，模块之间具有密切的联系，前一模块的输出结果可作为后一模块的输入条件。其中埋藏史、热史模块是由现今状态出发，逆时序恢复地层的古埋深、古孔隙度与古地温；而成熟史、生烃史与排烃史模块则以沉积物开始沉积时为起点，顺时序再现烃源岩有机质热演化、生烃与排烃等地质作用的过程，给出成熟度、生排烃强度、排烃效率等结果。所有模块结果均可作为地质时间的函数。

| Abstract: | A simulation model of histories of evolution and hydrocarbon generation and expulsion of source rock is put forward in this paper. The model includes five model blocks:burial history,geothermal history,maturity history,hydrocarbon generation history and hydrocarbon expulsion history.There is a close relation among these model blocks,and the output result of a model block can be used for input condition of next one.The burial and geothermal histories are recovered backward in time order,but the maturity history and the histories of hydrocarbon generation and expulsion are reconstructed forward in time order.Being the important ouput results,the depth,temperature,porosity,maturity,intensities of hydrocarbon generation and expulsion are given as the functions of geologic time. |
