摘要
电火花震源是一种重要的海洋地震勘探技术装备。它不仅环保、安全、成本低,而且数据具有宽频带优势,能够实现高分辨率地震勘探。但电火花震源在发展初期,存在信号不稳定、勘探深度浅等问题,导致它的发展速度减慢而被气枪震源所取代。后来,随着电力电子技术的快速发展以及数据处理水平的提高,这些问题逐渐得到解决,近年来逐渐又引起了人们的重视。文中概括了电火花震源的硬件、数据处理方法的发展历程,总结了电火花震源发展过程中存在的问题,阐述了前人使用电火花震源地震勘探的应用效果,从数据处理角度提出了解决存在问题的方法,展望了电火花震源对于未来海洋地震勘探的前景以及发展方向,认为电火花震源在未来海洋地震勘探中将会发挥更大的作用。
Sparker is an important equipment for marine seismic exploration technology.It not only is environmentally friendly,safe and low-cost to use,but also has broad frequency advantages for data,which can improve the resolution of seismic exploration.However,in the early stage of its development,there existed some problems such as unstable signals and shallow penetration depth,which caused its development speed to slow down or even to be replaced by air gun source.Later,with the rapid development of electronic technology and data processing level,these problems have been solved very well,and it also has attracted people’s attention once again.This paper reviews the development of sparker source hardware and data processing methods,summarizes the problems existing in the process of sparker source development,expounds the application effect of sparker source used by previous researchers,proposes a solution from the data processing,and predicts the future and important developing direction of the sparker source in marine seismic exploration.The authors hold that sparker source will play a much more important role in marine seismic exploration and this will have significant studying meanings for the improvement of marine seismic exploration,sparker source hardware and source data processing methods.
