摘　　要：注水井注水量向各产层的劈分或在平面上向各生产井的劈分以及生产井产液量在纵向及横向上的劈分,是了解注入水流场分布和储层中原油动用状况,制定井网调整与调堵措施方案的基础性工作。本文叙述了劈分系数法,提出了劈分量的最小二乘近似求解法,当未知量个数少于方程个数时,先关于未知量求偏导使其等于零,得到与未知量个数相同的方程数,再利用矩阵运算解出未知量,通过实例验证该方法是正确和可行的。Water-injected volume of injection well splitting to every pay formation or production well on the plane and liquid producing capacity of production well splitting to the vertical and horizontal,which is a foundation work that understands the distribution of flood water flow field and the use of crude oil in reservoir conditions,then develops the well network adjustment and takes steps on sealing.This paper describes the method of splitting coefficient and proposes the approximate solution of Least Square Method on splitting component,when the quantity of unknown variables is less than that of equations,we'll solve partial derivative of unknown variables first and make it equal to zero,then obtain the same number of unknowns in the equation number,finally use matrix operations to solve unknown quantities,we also verify the feasibility and validity of this method by example.
