高密度高分辨地震勘探技术在渤海PL地区的应用

随着地震勘探技术的提高,以高空间采样率为显著特征的高密度地震勘探技术取得了重大进展。为探索高密度高分辨三维地震采集技术在海上的应用,在渤海PL地区地震资料采集中首次在国内应用了横向鸟技术,缩小了资料的面元尺寸,同时优化了震源、电缆等施工参数。同时,通过针对性的高分辨处理,成果资料在横向和纵向分辨率上都有很大提高,反映的地质信息更为丰富,有助于提高对断裂系统的认识能力,增加了可供选择的钻探目标。

Application of High-Density and High-Resolution Seismic Exploration Technology for PL Zone in Bohai Sea

With seismic exploration technology improved, the high-density seismic exploration technology characterized in high space sampling rate has made a great progress. To explore offshore application of this high-density and high-resolution 3D seismic acquisition technology, transverse bird technology was used for the first time at home for seismic data acquisition in PL zone of Bohai Sea, reducing bin size of data and optimizing parameters of seismic source and cable. Meanwhile, based on high-resolution processing, the data results were significantly improved in terms of transverse and vertical resolution, reflecting more abundant geological information, helping understand the fault system and adding exploration targets for selection.
