摘要
近年来地震勘探硬件设备正在逐步发展,地震采集道数已从原来的几百道发展为几千道,甚至上万道。由于采集道数的增加,陆上宽方位角三维地震勘探已经成为可能。本文通过中国西部的宽方位角采集、处理和解释的实例研究,在比较了宽、窄方位角三维地震在振福成像、相干数据体和相位的差异后,认为宽方位角地震勘探在岩性和方向性裂缝勘探领域具有广阔的应用前景。
Hardware equipment of seismic exploration has been gradually developed in recent years, the numbers of acquired seismic trace are expanded from original several hundreds to several thousands, even ten thousands,which makes land wide-azimuth 3-D seismic exploration possible. Through cases study of wide-azimuth acquisition,processing and interpretation in the west of China and after comparison of differences in amplitude imaging,coherent data volume and phase for wide-/narrow-azimuth 3-D seismic exploration, the paper considered that the wide-azimuth seismic exploration has widespread application prospect in lithologic and directional fracture exploration.
