蚂蚁追踪技术在童亭109采区小构造解释中应用

Application of Ant Tracking Technology on Minor Structure Interpretation in Tongting Coalmine Winning District No.109

童亭煤矿109采区进行了三维地震勘探工作,落差在10m以上断裂基本被确认,小于5m断层较多,靠肉眼识别难以保证解释的准确性,且效率较低,为此引入了蚂蚁追踪技术对小断层进行解释。首先对三维地震数据体进行边缘处理,调整参数得到不同蚂蚁追踪数据体,然后提取沿层属性切片,进行属性异常筛选和评价,优选出符合本地区的计算参数,最终完成对地质小构造的精细识别。在该采区,地下实际巷道揭露断层18条,利用蚂蚁追踪技术获得的属性体沿层切片显示的异常有14处,可见,该技术能够有效的指导人工地震解释工作,清楚直观的显示断裂痕迹,实现小构造的精细识别,具有一定有效性和实用性。

The 3D seismic prospecting has been carried out in the Tongting coalmine winning district No. 109, faults with throw over 101n are basically ascertained. But many minor faults with throw less than 5m are hard to be interpreted megascopically and with low ef- ficiency, thus the ant tracking technology introduced. Firstly carry out edge processing for 3D seismic data volume, adjust parameters and get different ant tracking data volumes. Then extract bedding attribute slices, carry out attribute anomaly selection and assessment, optimize computation parameters in accordance with the area. Finally fulfill minor structure fine discrimination. In the winning district, 18 faults have been revealed by underground roadways; 14 anomalies displayed on attribute volume bedding slices through ant tracking technology. It is thus clear that the technology can effectively guide the artificial seismic interpretation, clearly and intuitively display fault traces, and realize minor structure fine discrimination with certain effectiveness and practicability.
