油藏非均质性的定量描述方法在油 田开发， 特别是在三次采油中起着至关重要的作用。仅仅通过对静态资料 如测井、取心和地震资料的解释而建立的地质模型不能很好地说明流体在多孔介质的渗流特征。在前人研究的基础上，从油藏的实际情况出发，如油藏由多个小层构成，每个小层的有效厚度、流体饱和度分布不同的特点，将脉冲试井与数值模 拟理论有机地结合在一起，通过模拟脉冲试井过程，将计算结果与实测的脉冲反应曲线做对比，修正初始的地质模 型，最 终可获得油藏各小层的渗透率非均质分布图。这种动态资料与静态描述相结合的油藏描述方法可为聚合物采油技术的开展提供可靠的地质模型。以大庆油田单层注聚合物试验区为例，说明了这种方法在油田开发中的应用。
The quantitative description of reservoir heterogeneity plays a crucial role in oilfield development, especially in tertiary oil recovery. Geological models established solely by interpretation of static data such as logs, coring, and seismic data do not provide a good indication of fluid seepage characteristics in porous media. Based on the previous studies, based on the actual reservoir conditions, if the reservoir consists of many small layers, the effective thickness of each small layer and the distribution of fluid saturation are different, the pulse well test and numerical simulation theory By means of simulating the pulse well testing process, the calculated results are compared with the measured pulse response curves, and the initial geological model is amended to finally obtain the heterogeneous distribution of permeability in each small layer of the reservoir. This dynamic data combined with static description of reservoir description method can provide a reliable geological model for the development of polymer recovery technology. Taking Daqing Oilfield single layer polymer injection test area as an example, this paper illustrates the application of this method in oilfield development.
