摘要
宽线大组合联合观测技术是近年来地震采集攻关取得的重大创新技术成果。针对复杂山地地震资料低信噪比问题,在大量理论研究和野外攻关试验的基础上,创新了宽线大组合联合观测技术,并且形成了一套完整的宽线大组合联合观测技术设计方法和野外施工质量保证措施,使地震资料信噪比取得显著的提高,成像质量得到显著改善,为发现和锁定构造发挥了重大作用。目前该技术已经成为复杂山地高陡构造地震勘探的主打技术,得到了全面的推广应用。
Broadened line plus large geophone array technology is seismic acquisition in recent years made significant innovationof technological achievements.For complex mountainous seismic data of low signal-to-noise ratio,in a large number of theoreticalstudy and field test,on the basis of technological innovation in the wide line combination joint observation technology,and formed acomplete set of big wide line combination design method of combined observation technology and field construction quality assurancemeasures,the signal-to-noise ratio of seismic data to significantly improve,improve image quality significantly,to discover andlocking structure played a major role.At present this technology has become a complex mountainous seismic exploration of high andsteep structure main technology,obtained the comprehensive popularization and application.
