用方差体技术识别小断层及裂隙发育带

APPLICATION OF VARIANCE CUBE TECHNOLOGY TO THE INTERPRETATION OF SMALL FAULTS AND FRACTURED ZONES

为了提高煤田开采的效率,准确、快速地确定断层和裂隙发育带已迫在眉睫。而三维方差体技术突出了地层横向变化对地震道的影响,能够对三维地震地质信息进行提取,还可用于识别断层、裂隙及地层的不连续变化。这里介绍了三维方差体技术的原理及基本算法,并在山东某采区三维地震资料的解释工作中进行了实际应用。结果表明,方差体技术对断层、裂隙发育带等地质异常体具有良好的识别效果。

The research of faults and fractured zones is very important in coal mine security and production.It is the high time to detected faults and fractured zones accurately and raise the efficiency of coal mine exploitation.3D variance cube technology have given prominence to the influence which were made by the horizontal change of strata upon seismic stack,can be drawn to detect 3D seismic geology information,faults,fractured zones and stratum variety. The theory and basic algorithm of variance cube technology is introduced in this paper,and the actual application in Shandong coal mine is presented and the results show that this technology is effective in the recognizing of small scale faults and fractured zones.
