摘　　要：利用流体包裹体测试数据结合热力学计算可恢复油气运移时期的古流体势,从而有助于预测油气富集区。通过惠民凹陷南部缓坡带的100多个包裹体分析,结合区域地质资料,研究了该区沙河街组四段地层在明化镇时期的古流体势分布,认为钱502及曲斜8为该区油气充注时期的低势区,有利于油气聚集。Paleo-fluid potential during hydrocarbon migration can be resumed by using fluid inclusion test data in conjunction with thermodynamics calculation.This is helpful to the prediction of petroliferous zones.The distribution of paleo-fluid potential has been analyzed for the fourth member of the Shahejie formation in the Minghuazhen period based on analyses of more than 100 fluid inclusion samples from the south slope of Huimin Sag combining with regional geologic data.It is thought that the Qian-502 and QX-8 well are low potential zones during hydrocarbon charging period,and are favorable sites of hydrocarbon accumulation.
