地震地貌学在隐蔽油气藏勘探中的应用
|
摘要
地震地貌学是近年来迅速发展的一门新兴边缘学科,它利用从三维地震数据中提取出的振幅属性,借助三维可视化技术成图,结合地貌学知识以促进对地下地质情况的认知和研究,对有利储集体进行预测。应用地震地貌学方法进行隐蔽油气藏勘探,不仅赋予了地震相和地震属性全新的地质学和沉积学概念,也客观地再现了隐蔽油气藏中各类储集体三维空间形态及其内部沉积构成变化。文章概述了地震地貌学的概念,并结合国内外的相关研究,列出一套可供参考的工作流程,介绍了它的关键技术,提出了地震地貌学在隐蔽油气藏勘探中的优势。
Recently Seismic geomorphology has became a new interdisciplinary subject,by the use of seismic amplitude attributes,3D visualization technology into a map,and the knowledge of geomorphology in order to promote the ability to recognize underground geological conditions and research on the favorable reservoir prediction.With the application of seismic geomorphology to explore the subtle reservoir,not only gives the seismic facies and seismic attributes the new concepts of geology and sedimentology,but also objectively show the subtle types of reservoir oil and gas reservoirs form 3D space and the changeof its internal sedimentary composition.The article gives the concept of seismic geomorphology,the reletive research at home and abroad,listing a set of reference workflow,describes its key techniques,and the advantage of seismic geomorphology in subtle hydrocarbon pool exploration.
