【摘要】 煤矿高产高效安全生产地质保障体系要求探明煤矿微小构造,相干体技术利用计算机分析检测三维地震数据体中相邻道之间地震信号的相似性,比常规解释方法更有利于小断层等小构造的识别;相干技术算法中C3比C1、C2两种相干算法在断层识别和边缘检测上具有更高的水平分辨率和垂直分辨率;相干体技术与地震属性技术、图象处理技术联合使用,形成煤田地震资料解释的新模式,能够更好地解决煤矿生产中遇到的构造、岩性等实际问题,极大提高三维地震成果的使用效率和应用水平;相干体技术在许厂、梁家等煤矿中应用取得了良好效果.更多还原

【Abstract】 To ensure safe and efficient production,the minor structure of coal mines must be acquired.The coherence technology applies PC to analyzing the similarity of seismic signals between adjacent channels and it can easily identify the minor structure(such as fault) than conventional technologies.Compared with C1 and C2,C3 features higher horizontal and vertical resolution on fault identification and edge detection.The joint use of the coherence technology with seismic attribute and image processing technology provides a better solution for structure and lithology problems encountered in coal mine productions,greatly enhancing the efficiency and application of three-dimensional seismic method.The coherence technology finds good application in Xuchang and Liangjia coal mines.更多还原
