高密度三维地震技术在潞安矿区高河煤矿的应用效果
|
摘要
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 prospecting test was carried out in the Gaohe coalmine,Luan mining area.Through the test has obtained rational acquisition parameters in the area,multiple key techniques used in processing and interpretation,such as frequency-division residual statics iteration,prestack time migration,forward modeling,3D visualization,attribute body slice and colored profile combination technologies.The interpreted results contrast between high density and conventional 3D seismic prospecting have demonstrated that the former can improve accuracy and precision of structure imaging and avoid misjudge and improve lower group coal seam reflection energy and continuity,thus an effective technical means to improve 3D seismic prospecting precision in the Luan mining area.
