摘　　要：为提高双重介质裂缝型油藏数值模拟历史拟合的精度和效率,建立了适用于裂缝发育储层的双孔双渗注采模型,选定了渗透率、平面与纵向渗透率比值、sigma因子、相渗曲线四类油藏参数,从基质与裂缝两个维度确定了各参数敏感性特征,并应用到国外某碳酸盐岩裂缝型油藏,取得了提高拟合精度及效率的效果。In order to improve the accuracy and efficiency of the reservoir simulation history matching for dualmedia fractured reservoirs,a dual poro&dual perm model was established.Four types of reservoir parameters of permeability,plane and vertical permeability ratio,sigma factor and relative permeability curve were selected,and the sensitivity characteristics of each parameter were determined from the two dimensions of matrix and fracture.Finally,a foreign fractured carbonate reservoir was applied,and the effect of improving the matching accuracy and efficiency was achieved.
