地震资料的三维空间交互式层面追踪解释方法研究
|
摘要
地震资料的层面解释是对现有的地震层面数据进行分析和处理,然后再以各种直观的方式动态展示地质特征的物探方法,是各种地质和能源勘探中的一项重要技术。解释效果的好坏直接影响后继工作的效率和成败。传统地震资料的层面解释方法建立在对三维地震资料进行二维解释的基础上,这种方法简单便捷,但也有很多的不足之处,如资料利用率低、解释精度不高等。本文提到的剖面引导和数据子体引导是两种全新的三维空间交互式层面追踪解释方法,从控制层面追踪区域的大小、控制层面追踪的次序等多个方面很好地弥补了传统方法的不足并阐述了这两种方法的原理、优点并给出了具体的实现算法和效果图。
Layer interpretation is some kind of analysis and processing of seismic data.Aided by the result,geological characteristics can be dynamically shown intuitively.Now,it is an important technology in the process of geological and resource exploration.The effect of interpretation affects the efficiency and success of follow-up directly.Traditional interpretation methods have lots of drawbacks because of its 2D interpretation approaches based on 3D seismic data,such as low utilization rate of information and rough accuracy.Two new three-dimensional interactive layers interpretation methods of profile guidance and data volume guidance are introduced in the paper which compensate for the deficiencies of traditional methods from different aspects.The principle and advantages are analyzed,and at the same time the implementation algorithms and effect pictures are given.
