| 摘 要： | 在油田开发中 ,研究水驱能量大小对油井产量的影响具有重要的意义。定义水驱强度为水侵量与油井产量之比 ,建立了考虑水驱强度影响下 ,油井定井底压力生产时 ,水驱油藏中水驱油瞬时渗流的数学模型 ;在获得数学模型的解后 ,作出了水驱油藏中油井产量变化关系曲线 ;研究了水驱强度及油水流度比对产量变化关系曲线的影响 ,分析了渗流特征。此研究为分析水驱油藏中油井的产量变化规律提供了理论基础。

| Abstract: | In development of oil fields,it is significance to study magnitude of water-drive energy effect on production of oil well.Considered the influence of the magnitude of water energy which is defined as ratio of influx and production of oil well,a mathematical model with effect of water drive strength at constant well-bore pressure has been built.The production relationship curve of oil well is calculated by obtaining solution of mathematical model.The effect on production relationship curve by water drive strength and oil-water mobility ratio have been studied and the percolation characteristics is analyzed which provides theoretical bases for analyzing production change of oil well in water-drive oil reservoir. |

| Keywords: | water-drive oil reservoir oil well strength of water-drive oil-water mobility change of production |
