Abstract: A multi-target mathematical programming method to dE:tc:rmine the optimum number of wells for field development is presented.For enhancing economic efficien cy,two-target funcations for maximization of cumulative oil production and minimization of total investment cost are developed an the basis of reservoir engineering theories and optimization techniques.An evaluation function is derived and the optimal solution can be obtained by L.agrange multipliers.An example is given.

Key words: field development, the optimum number of wells, evaluation, function, method

摘要： 提出一种确定油田开发最佳井数的多目标数学规划方法.根据油藏工程理论和最优化理论,从提高油田开发经济效益出发,建立总采油量最大和油田总投资费用最小两个目标函数,用多目标数学规划方法,构造评价函数,用Lagrange乘子法求最优解,并进行了实例计算.
