摘要
概念模型是各油田开发阶段都经常应用的一种储层地质模型。本文通过一个实例,比较详细地介绍了建立碎屑岩储层概念模型的工作步骤和方法。以岩心资料为基础,通过微相分析,作出各微相的典型柱状剖面;利用电相作出的平面相分布图,作为井间参数预测的依据;根据沉积类型估计层内不连续夹层的大小和频率。也介绍了一些实际操作中的处理方法。
Conceptual model, a kind of the geological model of reservoirs, is often used in all the development phases of an oilfield. Through describing a case example, this paper introduces the procedure and method for building a conceptual model of the clastic reservoirs, of that the foundamental points are: (1) building the typical column of each microfacies based on the cole data and microenvironmental analysis: (2)making interwell prediction of the petrophysical parameters in term of the areal distribution of microfacies derived from electrofacies analysis: (3)estimating the dimension and frequency of discontinuous barriers according to their depositional characteristics. Also, some treatment ways for operation are mentioned. All of these could be referred in practice.
