摘要
含油气系统作为沉积盆地中油气藏形成和演化的独立地质单元,其中的油气藏分布与盆地类型和生烃洼陷等有着良好的成因联系。这种自然分配过程可以用发现过程模型来描述和分析,进而作出科学预测。利用对数正态模型对辽河盆地某含油气系统中油气藏规模的研究证实了这种方法的有效性。
There are good genetic relationships between hy-drocarbon distribution and basin type as well as gen-erative source in a petroleum system, which is regard-ed as relative independent unit of the formation andevolution of oil & gas pool in sedimentary basin. Thisnatural process can be described and analyzed bymeans of discovery process model, furthermore, sci-entific predictions can be made. The research of oil & gas pool size prediction in a petroleum system ofLiaohe Basin was implemented using log-normalmodel, and the effectiveness of the method was alsoproved.
