断陷—拗陷型盆地中油气物质的生烃史,势必受断陷—拗陷原型迭加的埋藏史约束和控制,从油气源岩到圈闭建立油气成藏的观念,必须纳入到盆地系统中,明确盆地地质作用与油气响应之间的关系,确立原型控制油气P(压力)、V(体积)、T(温度)动态变化的边界条件,同时利用TSM盆地模拟系统动态地进行生烃量计算和生烃史的分析,从而为油气资源评价和勘查服务。

The hydrocarbon-generation history of the oil and gas materials in a fault subsidence-depression basin is certainly restricted and controlled by the burial history of fault subsidence-depression prototype superimposition.The idea of petroleum reservoir-forming from hydrocarbon source rock to trap must be brought into the basin system.Based on this idea,the relationship between geologic process and its response in a basin can be determined,and the boundary conditions that the prototype controls the dynamic changes of pressure(P),volume(V) and temperature(T) are established.At the same time,the TSM basin modelling system is used so as to calculate the hydrocarbon-generation quantity and analyze the hydrocarbon-generation history.
