【摘要】 辽河外围盆地LX地区构造复杂、干扰发育、近地表吸收衰减严重,是典型的地震资料低信噪比地区。通过可控震源滑动扫描技术、井震分区联合激发方式和海量地震数据实时质控技术的联合应用,成功实施了高覆盖、宽方位三维地震采集方案,大幅提高了LX地区地震资料品质,显著改善了深层构造的成像效果,取得了滑动扫描高效地震采集技术在辽河外围盆地首次工业化应用的成功,也证明了可控震源滑动扫描高效地震采集技术在东部探区复杂地表区应用的可行性。更多还原

【Abstract】 LX Area in Liaohe periphery basin was a typical area of low signal to noise ratio of seismic data because of complex structure,interference wave development and serious near-surface attenuation.By applying sliding-scanning technology based on vibroseis,well-seism sectional joint shooting and real-time quality control of massive seismic data,a 3D seismic acquisition scheme with high coverage and wide azimuth was implemented successfully,the quality of seismic data and imaging in the was improved significantly in LX Region.The imaging effect of deep structure was obviously improved,the first successful industrialized application of sliding-scanning efficient seismic acquisition was is made in Liaohe periphery basin.Meanwhile,it demonstrates the feasibility of sliding-scanning efficient seismic acquisition in complex surface areas in oil exploration area in East China.更多还原
