Abstract: This paper has worked out simplified basic equations for the different types of flooding pattern in the predication of performances of Oil field development, including oil wafermobility ratio, areal Sweep efficiency and interference between production wells, taking into consideration the effect of non-piston-like displacement of oil by water, and neglecting the effect of gravity and capillary pressure. For flow of homogeneous fluid(mobility ratio=1) under piston-like displacement, the formulas derived in this paper agree well with the ideal equations by Muskat and Krutter. The methods proposed in the paper may be used for prediction of injection rates and production trends for different flooding patterns before and after breakthrough, applicable also to heterogeneous reservoirs.

摘要： 本文分析了不同面积注水系统基本方程式的简化处理,这些预测开发动态的方程式,包括了油水流度比,面积波及系数和生产井间干扰的综合影响。同时,考虑了水驱油的非活塞性,但忽略了重力和毛管压力的作用。本文提供的方法,可以用来预测不同面积注水系统在油井见水前后的注水量和开采历史。它同样可以用于非均质油藏的计算工作。
