摘 要: 本文在考虑原油粘度随时间变化的基础上,提出了一种计算油藏动态的方法,指出这种方法与其它考虑参数变化方法相比具有的优点。同时利用油田实际资料对一维驱替情况进行了计算,计算并对比了考虑粘度时变和不考虑粘度时变条件下油藏开发评价指标和地层中剩余油饱和度的分布,分析了两种条件下存在的差异及其造成差异的原因。如果按照这种计算方法,再考虑地层渗透率及相渗曲线的时变性,可以得到一套适合处于于高含水开发期油田的开发效果评价方法。
关 键 词: 油气田开发工程;时变参数;原油粘度;开发指标;剩余油分布

Abstract: Taking consideration of crude oil viscosity which is varying with development of oilfield, the paper puts forward one method to calculate reservoir parameters, predicts the method’s advantages compared to other methods. At the same time, the paper calculates one dimension reservoir’s producing index, indicates the differences of reservoir developing evaluation index and the distribution of residual oil between parameters varying with time and parameters without varying. If taking considerations of the variety of permeability and the relative permeability curves additionally, the method may be a good method to calculate reservoir index.
Key words: oilfield development engineering; parameters varying with time; crude oil viscosity; developing index; the distribution of residual oil
