时移地震流动单元自动追踪与解释成果分析
|
摘要
为了更加即时、形象地解释时移地震的数据资料,先从理论上详细解释了流动单元的概念,并分析了时移地震中所用到的必要技术,然后给出了解释时移地震数据的三维可视化技术,最后构造出了时移地震流动单元的数据结构,并根据这种数据结构探讨的三维可视化技术,阐述了从剖面和切片2种角度上解释流动单元时逐步增加解释点并最后实现成功解释的方法。并利用该解释方法通过一个具体的实例数据集展示了处理效果。
Time-lapse seismic is an advanced geophysical technology which is called 4-D seismic in recent years.The concept of flow-unit is detailed explained in theory.And simultaneously a few key technologies including three-dimensional visualization technology is analyzed in the paper.The concept and concrete data structure of flow-units are given.And how to increase interpretation points on sections and slices during flow-units interpretations are discussed detailedly.The treatment effects are shown based on an actual example in the end of the paper.
