【摘要】 在油田开发区实施高密度地震观测面临很多技术难点,如油田设施密布造成的施工障碍、外界环境干扰发育导致的地震数据信噪比下降、高密度激发的海量野外工作量等。针对这些难点,在克拉玛依油田几个高密度试验区探索了配套的高密度地震数据高效采集技术,包括施工预设计、可控震源交替扫描、超级排列接收、震源性能实时监控以及科学合理的生产组织等,在实际应用中取得了良好的效果。更多还原

【Abstract】 High-density seismic acquisition faces many difficulties in the developed regions of an oilfield.Dense infrastructure impedes acquisition operation,serious industrial noises lead seismic data to low S/N,high density of shots means a huge amount of acquisition workload.This paper discusses some efficient acquisition techniques developed from several high-density seismic acquisition experiences,including layout pre-design technique,flip-flop shooting,super-array receiving,real-time monitoring for vibrator performance,scientific and rational organization of production and other supporting technologies.更多还原
