| 摘 要： | 方差体技术是基于统计学原理,利用三维地震数据体中相邻道之间地震信号的相关性计算样点的方差值,提取数据体中不连续信息,用以识别小断层和陷落柱等岩性变化点。笔者以山西某煤矿采区为例,通过方差体各项参数的测试,介绍方差体的运算模式、运算道数和时窗大小等参数对计算成果的影响,使方差体技术在确定煤层小断层和陷落柱等地质体时取得较好效果。

| Abstract: | The variance cube technique is based on the statistic principle. The correlation of the seismic signals between the neighboring channels in the 3D seismic data body is used to calculate the variances of the sample spots and extract the discontinuous information in the data body, with the purpose of recognizing such lithologic variation spots as small faults and collapse pillars. Exemplified by a mining area in a coalfield of Shanxi Province and based on testing various parameters of the variance cube, this paper deals with the effects of such factors as the operation mode of the variance cube, the channel number of the operation and the size of the time window upon the calculation results. With the achievements made by the authors, the variance cube technique can yield relatively fine results in detecting such geological bodies as coal seam small faults and collapse pillars. |
