GeoEast三维可视化技术在断层识别中的应用

Application of GeoEast 3D Visualization Technology in Fault Recognition

摘要: 断层解释是地质研究中最重要的组成部分之一，直接关系到勘探开发目标优选，断层解释精度直接影响地质认识和开发效果。近年来众多学者在断层解释方法上的研究投入大量精力，相干、曲率、蚂蚁体等数学算法及其改进得到长足发展，断层识别精度得到大幅度提升。单纯数学算法基于地质概念出发，但在运算过程中单纯依赖计算结果，难免出现多解性，仍然需要地质专家逐一清查，对于低序级断层的识别仍然存在不确定性。借助GeoEast软件的三维可视化技术，将断层作为异常地质体进行空间雕刻，使其更加直观地展示在地质专家面前，帮助地质专家解决低序级断层存在与否的问题。

Abstract: Fault interpretation was one of the most important components in geological research, which was directly related to the optimal selection of exploration and development targets. The fault interpretation accuracy directly affected geological identification and development effect. In recent years, many scholars have put more effort into the research of fault interpretation methods, such as coherence, curvature, ant body and other mathematical algorithms and their improvements have been greatly developed, and the accuracy of fault recognition has been greatly improved. Although the simple mathematical algorithm was based on the geological concept, in the process of operation, it was too dependent on the calculation results, and it would inevitably induce multiple solutions. It still needed to be checked by geologists one by one, and there still existed uncertainty in the identification of low order faults. In this paper, with the help of the three-dimensional visualization technology of GeoEast software, the fault is carved as an abnormal geological body, which makes the fault more intuitively display in front of geologists and helps geologists to judge whether the low order fault really exists.
