以地震、钻井和油气成藏动力学理论等为基础，对东濮凹陷濮卫地区油气输导体系进行了研究，分析了油气优势输导通道特征，量化表征了研究区内油气输导能力，研究了濮卫地区盖层分隔槽与供烃中心位置的相对偏移对油气优势输导通道及油气富集的影响。通过计算油气输导量，对断层的油气输导能力进行了定量评价。研究表明，濮卫地区东翼断层的油气输导能力大于西翼和南翼，濮卫洼陷带北翼古云集地区南部、东南翼濮65￣濮75断块区为下步精细勘探的有利区带。

The hydrocarbon transport system in Puwei region of Dongpu Sag was studied based on seismic data, drilling data and hydrocarbon accumulation dynamics. Characteristics of preferential hydrocarbon transport channels were analyzed, and oil-gas transport capability was also quantitatively characterized. And influences of relative migration between the separated trough of cap rocks and hydrocarbon supplying center upon favorable hydrocarbon transport and accumulation in the Puwei region were examined. Quantitative evaluation of hydrocarbon transport capability of faults is conducted by calculating the amount of fault transporting. The results show that the hydrocarbon transport capability of faults in east limb of Puwei region is greater than that of the west and south limbs. The south Guyunji region at the north limb in the Puwei sub-sag belt and fault blocks of Pu 65-Pu 75 at the southeast limb are suggested to be further favorable fine exploration zones.
