对潞安矿区高河煤矿进行了高密度三维地震勘探试验,通过实验获得区内合理的采集参数,并在处理和解释中采用了多项关键技术,如分频剩余静校正迭代技术、叠前时间偏移技术、正演模型技术、三维可视化技术、属性体切片和彩色剖面联合技术等。高密度三维地震勘探解释结果与常规三维地震勘探解释结果的对比表明,高密度三维地震能够提高构造成像准确度和精度,避免误判,还可以提高下组煤层反射波的能量和连续性,是进一步提高潞安矿区三维地震勘探精度的有效技术手段。
High-density 3D seismic exploration test was carried out in Gahe coalmine in Lu’an mining area, and reasonable acquisition parameters in the area were obtained through experiments. A number of key technologies were adopted in the processing and interpretation, such as frequency-division residual statics iteration, prestack time Offset technology, forward model technology, three-dimensional visualization technology, attribute body slice and color profile joint technology. Comparison of interpretation results of high-density 3D seismic exploration and conventional three-dimensional seismic exploration shows that high-density 3D seismic can improve accuracy and accuracy of structural imaging, avoid misjudgment and enhance the energy and continuity of reflected waves in the lower coal seam. To further improve the Lu’an mine 3D seismic exploration accuracy of effective technical means.
