摘　　要：为解决B-L水驱前缘理论中前缘推进位置的准确度有限问题,基于泊肃叶方程,通过联立油藏物质平衡方程,转化为地层压力与流管数的最小化问题,运用遗传算法寻优最小目标值,获取各注采方向的流管数,从而确定注采井间驱替面积。该模型量化了B-L方程中驱替面积参数取值,利用改进后的井间驱替面积计算公式,提高了连通的注采井之间水驱前缘推进位置的计算精度。计算结果更加符合油田实际生产,对类似油田的水驱开发效果评价,具有一定的借鉴和指导意义。In order to solve the problem of limited accuracy of front advancement position in B-L water drive front theory,and based on Poiseuille equation,the study in this paper transforms this problem into the minimization problem of formation pressure and flow tube number through the simultaneous reservoir material balance equation.By using genetic algorithm to optimize the minimum target value,the study obtains flow tube number in each injection-production direction,and determines the displacement area between injection-production wells.The model quantifies the displacement area parameter value in the B-L equation,and uses the improved calculation formula for the displacement area between wells to improve the calculation accuracy of the advancing position of the water drive front between the connected injection and production wells.The calculation results are more in line with the actual oilfield production,and have certain reference and guiding significance for the evaluation of the development effect of similar water drive oilfields.
