煤田采区三维地震精细构造解释方法

虽然煤田三维地震勘探已经过了十多年的发展，但构造解释问题仍是目前需要解决的主要问题之一.随着三维地震资料解释方法的不断发展，小波分析技术、相干体技术、地震属性技术、图像处理等提高解释精度的方法相继在地震勘探领域中得到应用.另一方面，由于煤矿采区三维地震勘探资料一般具有高信噪比和高分辨率的特点，为做好三维地震资料精细构造解释提供了物质基础.本文结合小波分析技术、相干体技术、地震属性技术等多种方法，结合两个采区的实例，对小断层和小规模陷落柱做了精细构造解释.解释结果显示联合使用以上几种解释技术，能提高三维地震资料的构造解释精度和可靠信.

Detail structural interpretation methods of coal 3-D seismic

By over ten years' developing of coal field 3-D seismic exploration,but the structural interpretation also is a key problem needing to be solved.With the developing of interpretation methods of 3-D seismic exploration,wavelet analysis,coherence technology,attribute technology,and image process have been used to improve interpretation's precision.Coal mine's seismic data has the character of high resolution and high S/N ratio,and it is a good benefit to do detail structural interpretation of 3-D seismic.Such as fault or cavern interpret.In this article,above wavelet analysis,coherence technology,attribute technology and other methods are combined together to improve two real coal 3-D seismic data's precision of structural interpretation.This interpretation includes of fine faults and little scale cavern.After structural interpretation,the outcome shows that combining above methods can advance structural interpretation's precision and reliability of coal 3-D seismic.
