摘要: 油气聚集系数是油气资源评价中最为关键的一个参数, 影响因素复杂, 如何科学取值一直困扰着石油地质工作者.利用层次分析法建立油气运聚单元(油气成藏体系)定量评价结构模型, 对油气成藏体系进行定量评价; 根据“三高”原则选取刻度区, 利用生烃潜力法和油藏规模序列法求取刻度区的油气聚集系数, 将各油气成藏体系与刻度区类比求取相应油气成藏体系油气聚集系数.运用该方法求取苏北盆地高邮凹陷上含油气系统各油气成藏体系油气聚集系数.结果表明, 高邮凹陷上含油气系统各油气成藏体系油气聚集变化较大, 在9%~14%之间, 用该聚集系数求取的资源量较过去用一个统一的聚集系数求取的资源量更接近地质实际.实践证明, 利用层次分析法定量评价成藏体系, 结合生烃潜力法和油藏规模序列法, 可以对聚集系数进行定量预测, 减少资源量计算中人为因素的影响, 使资源评价更加客观.Abstract: The hydrocarbon accumulation coefficient is a key parameter influenced by many geological factors in the evaluation of hydrocarbon resources and how to attain its value scientifically has always been a big problem. In this paper, the hydrocarbon accumulation system is evaluated quantitatively by the quantitative evaluation model based on the analytical hierarchy process. The calibrated unit is selected according to the three-most principle and its hydrocarbon accumulation coefficient can be calculated by the methods of hydrocarbon-generation potential and pool size serial. The hydrocarbon accumulation coefficient of the intentional system can be gained by the analogy between the referential system and the intentional system. Through the application of the above methods, the hydrocarbon accumulation coefficient of the petroleum accumulation systems in Gaoyou sag of Subei basin can be satisfactorily attained, which proves that the hydrocarbon accumulation coefficient can be achieved quantitatively with the methods of hydrocarbon-generation potential and pool size serial based on the quantitative evaluation of the petroleum accumulation system by the analytical hierarchy process which leads to more objective hydrocarbon resource evaluation by decreasing the subjective factors in the calculation of hydrocarbon amount.
