南水北调陶岔渠首浅层三维地震勘探应用研究
|
摘要
三维地震勘探在资源勘探中已得到了广泛的应用,但在工程浅层勘探方面尚未见到成功的案例。本文通过南水北调中线工程陶岔渠首进行的三维地震勘探的应用,成功获取了探测区的三维地震数据体,并总结了适合浅层三维地震勘探的野外工作程序及数据处理流程。对比研究表明:三维地震数据体基岩面形态与地质剖面形态一致,深度相对误差在6.8%以内。
Three-dimensional seismic survey has been extensively used in resources exploration;the case of its successful application to engineering shallow exploration,however,has yet to be seen.This paper introduces the application of 3D seismic survey to Taocha,the beginning of the middle route of the South-North Water Diversion Project in which the 3D seismic data body of the target area was successfully acquired,and summarizes the fieldwork and data processing procedures for 3D shallow seismic exploration.The comparison shows that the bedrock surfaces shown in the 3D seismic data body is in accordance with geological profiles,and the relative errors of the depth are no greater than 6.8%.
