摘　　要：近年,地理地质信息勘查分公司在新疆塔里木盆地塔河地区进行地震资料采集项目时,针对地质目标“孔缝洞”的高精度成像,进行了10Hz与5Hz的动圈式检波器组合接收对比试验,经过分析论证,生产中采取“拓展低频、保护高频”的检波器接收组合方案,提高了奥陶系缝洞成像精度,所取得的检波器组合接收经验值得三维地震资料采集借鉴。In recent years,while conducting seismic data acquisition projects in the Tahe area of the Tarim Basin in Xinjiang,the Geophysical&Geological Information Prospecting Company targeted the high-precision imaging of geological objectives of“fractured vugs”.A comparative test between the combination receiving of 10Hz and 5Hz moving-coil geophones was carried out.Through analysis and demonstration,the operation adopted the geophone receiving combination pattern of“expanding low-frequency and protecting high-frequency”.This improved the imaging precision of the Ordovician fractured vugs.The geophone combination receiving experience obtained is worth referencing for 3D seismic data acquisition.
