摘　　要：依据翔实的勘探开发资料 ,利用构造应力场数值模拟方法 ,计算了南堡凹陷新生代东营末期构造应力场的分布特征 ;进而计算出流体势的分布特征 ;探讨了应力作用对油气运移的影响 ,分析了地应力与孔隙压力和流体势的关系 ;指出了油气运移的优选方向。On the basis of the full and accurate prospecting works,with the method of structural stress field numerical stimulation,in this paper the authors calculate the values of structural stress field in the Nanpu Depression at the late stage of Dongying in Cenozoic,and then describe the characteristics of its fluid potential.Moreover,the authors discuss the influence of the structural stress on hydrocarbon migration,analyze the relationship among the ground stress field,pore pressure and fluid potential,and point out the optimum direction of hydrocarbon migration.
