摘　　要：在油层低阻的成因分析中 ,以歧 5 0断块为列 ,从沉积因素影响入手 ,先确定低阻油层出现的目标区 ,而后对区内各井进行分析 ,确定其低阻油层的成因和解释标准 ,用双水模型法进行处理解释。It is found that the sedimentation factor plays a major role in origin of low resistivity oil zone from analysing Qi 50 fault block. At first, the target areas where the low resistivity oil zone exists are determined, and then,each well in the areas is analysed to establish the irreducible water saturation formula. In this article, an effective double water model is used for interpretation of such a kind of zone.
