沿测线进行多参数分析识别可能含油气范围的方法已在国内普遍应用。本文在分析单线多参数分析所存在问题的基础上，提出了利用地震资料进行油气藏灰色预测的思想。本文给出了采用灰色理论进行油气藏预测的方法原理及实施步骤，并以大港油田Q26井区为例，展示了该方法良好的应用前景。 Multi-parameter analysis along the line of sight to identify possible hydrocarbon-bearing range of methods has been widely used in China. Based on the analysis of the existing problems of single-line multi-parameter analysis, this paper proposes the idea of ​​using the seismic data to predict the gray level of oil and gas reservoirs. This paper presents the method principle and implementation steps of using gray theory to predict oil and gas reservoirs. Taking Q26 well of Dagang Oilfield as an example, this method has good application prospects.
