高陡构造勘探开发风险远大于平缓构造 ,其原因在于高陡构造地震圈闭要素及反射层产状与实际情况有较大差异 ,即高陡构造地震圈闭要素及反射层产状已发生畸变。本文应用地震勘探基本原理 ,采用模型正反、演技术 ,分析畸变现象及其产生的原因及危害 ,然后提出校正方法。作者根椐多年来从事高陡构造勘探的实践经验 ,提出高陡构造井位部署的 4项基本原则 ,它可起校正高陡构造地震圈闭要素畸变的作用
The risk of exploration and development of steep structures is much greater than that of flat structures. The reason for this is that the trap elements of high and steep structures and the occurrences of reflective layers are quite different from the actual ones. That is, the trap elements of high and steep structures and the occurrence of reflector have been distorted . In this paper, the basic principles of seismic exploration, the use of model forward and reverse acting technique, analysis of the distortion phenomenon and its causes and hazards, and then propose a correction method. Based on the practical experience of steep tectonics exploration for many years, the author put forward four basic principles for the deployment of high-steep wells and it can play a role in correcting the trap element distortions in high-steep tectonic earthquakes
