摘　　要：为了得到立体井网波及系数的影响因素,利用数值模拟方法,对五点法立体井网见水时刻的体积波及系数进行研究.结果表明,油水流度比、水平井穿透比、油水密度差异对立体井网体积波及系数的影响较大,立体井网体积波及系数与水平井穿透比呈线性关系,与油水流度比呈幂函数关系,与油水密度比呈指数关系.在对各关系曲线回归基础上,得到了五点法立体井网体积波及系数与各影响因素的定量关系.The sweep efficiency in 3D well pattern is different from that in conventional 2D well pattern. The volumetric sweep efficiency of five-point tridimensional well pattern at the water break-through moment is studied by numerical simulation. The result shows that the mobility ratio of oil to water,the penetrating ratio of horizontal well and the density difference between oil and water have great influences on the volumetric sweep efficiency of 5-point tridimensional well pattern,the relationship between the volumetric sweep efficiency and the penetrating ratio of horizontal well is linear,the relationship between the volumetric sweep efficiency and the mobility ratio of oil to water is power function,and the relationship between the volumetric sweep efficiency and the oil-water density difference is exponential. The quantitative relation between volumetric sweep efficiency and the affecting factors is established according to the regression of the relationships.
