Hydrocarbon Detection of Sand Reservoir Based on EEI Inversion
-
摘要: 埕岛油田是我国极浅海地区第一个投入开发的大油田,其馆陶组上段属河流相砂泥岩沉积,油气富集程度高。该层段分为五套砂组,其中三砂组和四砂组是主要的含油储层。此次研究的目标工区内主要的烃类是重质油,含油储层与含水储层的物性差异较小,通过反演常规的弹性参数无法准确指示油气。基于测井曲线和岩石物理交汇分析,本文构建了敏感的油气指示因子,通过扩展的弹性阻抗反演技术反演该指示因子从而进行油气展布预测。该方法在工区得到了良好的应用效果。Abstract: The Chengdao Oil Field is the first shallow sea oil field put into development in China. The upper Guantao formation is fluvial sand and shale deposition and it is enrichment in oil and gas. This formation is divided into five sand, the third and the fourth sand group are the main oil-bearing reservoir. The main hydrocarbon in this research area is heavy oil. Because of the difference of physical properties between oil-reservoir and water-reservoir is small, it is difficult to accurately identify the heavy oil through the traditional inversion. In this paper, a sensitive heavy oil indicator is constructed, and the oil indicator factor is retrieved by extended elastic impedance inversion. This method has good application in this area.
