本文提出的定量评价生油岩的TTT法,同时考虑了生油母质类型(T)、有机质成熟的温度(T)和时间(T)三个因素;它采用生油岩中不同类型干酪根在不同热演化阶片上的裂解烃产率、有机碳、氯仿沥青A和总烃等四个参数,可以直接计算生油岩的生烃量和排烃量.本文结合松辽盆地的实际资料,对青一段生油岩的生烃量、排烃量进行了计算,其结果与烃类垂向分布及有机质成熟史相吻合.
In this paper, the TTT method for quantitative evaluation of source rocks is given, taking into account three factors: type of parent material (T), temperature (T) of organic matter ripening and time (T); it uses different types of kerogens Hydrocarbon production and hydrocarbon expulsion can be directly calculated by using four parameters of pyrolysis hydrocarbon yield, organic carbon, chloroformic bitumen A and total hydrocarbon in different thermal evolution stages. According to the actual data of Songliao Basin, The amount of hydrocarbon generation and hydrocarbon expulsion in the first member of the Qingyuan oil source rock are calculated. The results are consistent with the vertical distribution of hydrocarbons and the maturation history of organic matter.
