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。
This paper proposes a method to combine the three dimensional geological model with GIS (Geographic Information System) spatial superposition analysis to study the distribution of favorable oil zones. The basic principles and steps are briefly described and the application examples are given. Firstly, the 3D geological model is characterized by two-dimensional planarization and GIS software is provided as an input attribute layer. After GIS spatial superposition analysis, the main geological parameters of the target layer of the block are effectively integrated. Finally, the grid image fuzzy model Identify or obscure the classification method to divide favorable oil zones. The research shows that the method is applied to the research of favorable oil area distribution in practice, has the characteristics of rapid and intuition, and provides a new method and new idea for the deepening application of 3D geological model.
