摘要
利用地球化学参数是计算烃源岩排烃效率的常用方法,但由于钻井取心成本高、样点分布局限,其结果难以反映烃源岩排烃的整体情况。通过对比高邮凹陷阜四段利用地球化学参数和测井声波两种方法计算的结果,证实烃源岩测井声波时差响应与排烃有着密切的关系,声波时差曲线形态能够较好反映烃源岩排烃特征,两种方法具有较好的一致性。利用测井声波时差计算烃源岩排烃效率具有一定的合理性和可行性。
The hydrocarbon expulsion efficiency of source rock calculated by geochemical parameters is a common method. But the overall condition of hydrocarbon expulsion of the source rock can not be reflected by the calculation result due to the high cost of drilling coring and the limited distribution of sample points. The results calculated by the geochemi- cal parameters and the interval transit time curve were compared in the fourth member of Funing Formation in Gaoyou Sag. It was verified that the logging response has a close relationship with the hydrocarbon expulsion of the source rock. The hy- drocarbon expulsion characteristics of the source rock can be preferably reflected by the interval transit time curve pattern. The result calculated by the geochemical parameters is in good agreement with the result calculated by the interval transit time curve. So it is reasonable and feasible the hydrocarbon expulsion efficiency calculated by the interval transit time curve.
