三维可视化技术在地震资料解释中的应用
|
摘要
介绍了三维可视化技术基本原理和流程的基础上 ,着重研究了其在地震资料解释中的应用。它主要包含 2方面 :一是可对三维地震数据体直接进行构造解释、实现空间域的层位自动追踪和断层的空间组合 ,解决复杂断块的构造问题 ;二是可进行储层描述 ,即可在一定时窗内或解释层之间进行岩性分析和沉积环境解释。以胜利油田探区为例 ,通过对 CG2 0复杂断块潜山进行精细的构造解释 ,及对 CJZ凸起和北坡的上第三系馆陶组—明化镇组河流相砂体和下第三系东营组三角洲相砂体的储层描述 ,说明三维可视化技术已在构造解释和储层描述中起到了不可替代的作用。
In this paper,the basic principle and flow chart of 3-D visualization are briefly presented and its application to seismic explanation is emphasized. It includes two aspects:One is direct structural interpretation and automatic layer-tracking and fault-linking in space for resolving the structural problems of complex fault blocks, the other is reservoir description, that is analysis and interpretation in certain time windows or between certain layers. Shengli Oilfield is used as an example, the fine structural interpretation of the complex fault block buried hills at well CG20, the reservoir description of the Neogene Guantao and Minghuazhen group's fluvial facies sandstone and the Paleogene Dongying group's delta facies sandstone in the northern slope and bulge CJZ show the indispensable function of the 3-D visualization technique in structural interpretation and reservoir description.
