广角地震采集综述
|
摘要
近年来,广角地震采集作为获取野外高质量地震数据的一种重要方法,愈来愈受到人们的关注。广角地震方法的优势是用于常规地震难以成像的差记录和无记录区的地震数据采集,其特点是大排列采集(偏移距达6～38km)、大药量激发、典型的采集装备(WARRP排列)、典型的观测系统(Global offset)、广角反射和折射联合观测等。开展正演模拟分析可以优化广角采集观测系统。
As a way of acquiring high quality seismic field data, wide angle (aperture) reflection and refraction pro-filing (WARRP) is receiving increasing attention. The advantage of WARRP over conventional seismic explora-tion is that it can be used in areas where conventional seismic exp oration failed to acquire desired quality of seis-mic data. This paper discussed aspects of WARRP acquisition, i acluding long offset acquisition, shooting withlarge charge, typical acquisition equipment and layout, and joint observation of wide angle reflection and refrac-tion, and pointed out that forward modeling facilitates the optimination of WARRP layout.
