3-D VISUALIZATION TECHNIQUE AND ITS APPLICATION IN SEQUENCE STRATIGRAPHIC ANALYSIS

Research Institute of Petroleum Explorotion and Development, CNPC, Beijing 100083, China

摘要: 油田开发工作中面临的许多复杂地层对比问题对层序地层学理论和应用技术提出了更高的要求,而三维可视化技术是一种基于三维体的真三维计算机解释技术,利用该技术可对三维地震数据直接解释地层的构造、岩性及沉积特征,尤其在分析地层的沉积体系方面可显示出其巨大的优势.本文在研究某油田复杂的层序地层关系时,将传统的层序地层分析方法与三维可视化技术相结合,并取得了很好的应用效果.

Abstract: Some new technology should be used to solve the complex problem of stratigraphic correlation in reservoirs.The 3-D visualization is a method of voxel-based seismic volume interpretation.The structural,stratigraphic and lithologic features can be identified directly from the 3-D seismic volume.It has a great advantage especially on sedimantary system analysis.The 3-D visualization technology combined with the method of sequence stratigraphic analysis was used in the complex stratigraphic correlation in a field,and a very good result has been received.
