摘要
随着“两宽一高”地震采集技术的不断发展,鄂尔多斯盆地已成功开展多个井震联合地震采集项目,项目中可控震源发挥出巨大优势,但如何实现井炮与可控震源的高度融合、高效采集仍面临诸多挑战,主要表现在点位布设均匀性差、障碍区实施率低、采集效率提升难等问题。通过对近年来复杂黄土山地区三维地震勘探项目的技术研究与分析,总结出井震联合高精度预案设计、VPM+SSC井震联合双源激发等先进技术,以上技术在2022年度鄂尔多斯盆地NXX三维项目中成功应用并取得了显著效果,开创了复杂黄土山地区井震联合高效采集的新局面。
With the continuous development of seismic acquisition technology of"2W1H",several explosive-vibroseis combined seismic acquisition projects have been successfully carried out in Ordos Basin,where vibroseis has played a great advantage.However,there are still many challenges on achieving the high integration and efficient acquisition of explosives and vibroseis.It is mainly manifested in the poor uniformity of point layout,low application rate of obstacle area,and difficulty in improving acquisition efficiency.Through the technical research and analysis of 3D seismic exploration projects in complex loess mountain areas in recent years,advanced technologies such as explosive-vibroseis combined high-precision pre-plan design and VPM+SSC explosive-vibroseis combined dual-source excitation are summarized.The above technologies have been successfully applied in the 2022 NXX 3D project in the Ordos Basin and have achieved remarkable results.It creates a new situation of explosive vibroseis combined with an efficient acquisition in loess mountain area.
