| 储层地质知识库的建立是储层建模过程中极为重要的一步,它为建模提供基本的条件数据及各种统计参数。本文总结了建立地质知识库的主要步骤及基本内容。在资料较少的情况下,需要借助原型模型来提供一些无法直接获得但对建模十分重要的参数,如砂体宽厚比、水平方向变差函数等。文中用3个实例较详细的介绍了建立原型模型的3种主要方法,分别是利用露头、成熟油田和沉积模拟实验建立原型模型,并比较了各自的优缺点。 |

| Abstract: |
| The establishment of the geological databases for reservoir rocks is a key step in reservoir modeling, and may provide basic data and various statistical parameters for reservoir modeling. The present paper deals with main steps and contents for the establishment of the geological databases. In the case of insufficient information and parameters on reservoir rocks, it is necessary to construct prototype models in order to determine some important parameters for the reservoir modeling. These parameters include width (length)/thickness (ratios), symmetrical coefficients, horizontal variation functions and so on. Three methods are introduced in detail into the construction of prototype models including:outcrops, close-spaced well areas and simulation experiments of modern fluvial and lacustrine sediments. |
