油田注采井网的结构复杂，环境恶劣，研究其波及系数等参数具有重要意义但尚无有效合理的方法。为此研究提出使用等值渗流阻力法考虑非活塞式水驱油推导出多分支水平井注采井网产能以及见水时刻波及系数。利用等值渗流阻力的方法，以非活塞式水驱油为研究载体，将注采井的渗流区按照3个阻力区的形式划分，合理推导出产能公式和波及系数的计算公式。仿真结果表明，穿透比和分支数是具有线性相关的关系，并随着穿透比的增加而使得分支数也在增加。数模仿真结果显示了较好的低误差性能，提高了采井网波及系数的计算精度，为提高油藏和采油工程精度具有重要的实践意义。

According to the complex environment and complicated structure of the well pattern for oil field, the research of the sweep efficiency coefficient was very important but without reasonable and effective method yet. The flow region is divided into three resistance zones. The productivity formula and sweep efficiency of well pattern with vertical injector and multilateral horizontal producer are derived. Simulation result shows that the pitching to embedding ratio and the branching number are in the linearity relation with the same increasing trend. The model simulation result shows that the performance of low error property is nice, and the calculation precision was improved greatly. It affords important value for the improving the oil production capacity and improving the oil exploring precision to a great degree in practice.
