用储集层地质模型和 GIS 软件确定有利含油区

提出将三维地质模型与 GIS（地理信息系统）软件空间叠加分析相结合研究有利含油区展布的方法,简述了其基本原理和步骤,并给出了应用实例。该方法首先将三维地质模型进行二维平面表征,提供给 GIS 软件作为输入属性图层,再通过 GIS 空间叠加分析,将区块目的层各项主要地质参数有效整合,最后以栅格图像模糊模式识别或模糊分类的方法划分有利含油区。研究表明,所述方法在实际中应用于有利含油区展布研究,具有快速直观的特点,同时为三维地质模型的深化应用提供了新方法和新思路。

Application of Reservoir Geological Model and GIS to Delineation of Favorable Petroliferous Region

This paper proposes a method for integration of 3-D geologic model with Geographic Information System (GIS) software to study of distribution of favorable petroliferous region, including its basic principle, steps and applied case. Firstly, the 3-D geologic model is characterized within 2-D space followed by getting graphical layers as input attribute of GIS. Then by analysis of the space superimposition of GIS, the various geologic parameters from target zones in studied area are effectively regulated, and finally giving delineation of favorable petroliferous regions in terms of grid image fuzzy-type diagnosis or fuzzy clustering approach. The study shows that this method is of quick and visual features and also provides new way and new idea for deepening application of 3-D geologic model.
