摘　　要：随着油气勘探目标日趋复杂,对地震数据质量的要求也愈来愈高,同时陆上地震采集道数的急剧增加,使得现有采集设备笨重、成本高、效率低的问题日益突出,地震采集技术面临严峻的挑战。无缆节点型系统、无线检波器网络等新技术的发展,其成本低、重量轻、系统可靠、采集数据质量高等优势在陆上高密度采集中日渐显现。基于数字传感器的加速度检波器与常规地震检波器相比,动态范围更大,更有利于记录深层弱反射信号,拓展地震频带。新一代产品为采集技术带来革命性变化或许很快就会到来。The exploration targets of oil and gas are getting more and more complicated,which poses stricter requirements for seismic data quality.And the fast increasing number of land seismic traces makes the problems that acquisition instruments are clumsy,costly,and ineffective outstanding.Cable-free node system and wireless geophone network shows great superiority in land high density seismic acquisition in terms of cost,weight,reliability,and data quality.Compared to conventional geophones,digital sensor based acceleration geophones are wide in dynamic range,which is favorable for recording weak signals from deep layers.The new generation products may soon revolutionize acquisition technologies.
