摘　　要：本文利用正交设计思想和数值模拟技术对影响水平井挖潜曲流河点坝砂体剩余油的影响因素做了研究，指出夹层特征是影响挖潜效果的主要因素。对水平井挖潜点坝砂体剩余油的机理进行了详细分析，夹层相对重叠长度综合反映了侧积夹层的各个特征，其大小决定了底水的脊进程度，直接影响挖潜效果。优化射孔也可以改善底水脊进程度，提高开发效果。By the methods of orthogonal experimental designs and numerical simulation technique, studying on the effects of exploiting remaining oil with horizontal wells in the meandering reservoir has indicated that the character of interlays is the main factor influencing the exploiting effect. According to the detail analysis on the mechanism of exploiting remaining oil in sand body of point bar, the relative overlap length of the interlays reflects all the characters of the lateral accretion generally, and its size determines the degree of bottom water coning which influencing the exploiting effect directly. As well, optimizing perforation programs can decrease the degree of bottom water coning and improve exploiting effect.
