摘　　要：本文以2013年度美国SEG年会上刊出的地震各向异性理论与多分量地震技术方面的学术论文为依据,通过各论文的技术剖析和对比分析,总结了该届年会所展示的多分量地震技术的发展趋势与研究热点.综合分析发现,多分量地震技术的发展具有如下几个明显的特点:1)油服企业成为多分量地震技术的主要推动者;2)成功应用的实例不断增长;3)海洋多波依然是多分量地震技术应用的主要领域,其中OBC、OBS、OBN与拖缆纵波的综合运用是其独有的特色;4)多分量地震数据处理与多波联合反演的一体化成为越来越明确的发展方向;5)纵横波速度及各向异性参数建模是制约多分量地震偏移成像的关键因素,也是当前的研发热点;6)在纵波成像与反演困难的成熟勘探与开发区域,是多波地震发挥效用的理想场所,而不仅限于致密气等非常规裂缝型油气储层.On the basis of the published academic dissertations about theory of seismic anisotropy and multi-component seismic technology during 2013 SEG annual meeting,this paper summarized current research focuses and trend in this field.Comprehensive analysis shows obvious characteristics：1）Oilfield service companies become the main promoters in developing multi-component seismic technology;2） Number of successful application is increasing;3） Major application fields of multi-component seismic technology still lies in marine,especially with the comprehensive application of OBC,OBS,OBN and streamer seismic P-wave;4） It becomes specific that integration of processing and joint inversion in multi-component technology is the development direction in the future;5）Modeling of P-wave and S-wave velocity,as well as anisotropic parameters,are the key factors and also research focuses in restraining the multi-component migration imaging;6） Multiwave seismic technology have effectiveness in developed areas which have difficulties in P-wave imaging and inversion,not limited to unconventional fractured oil and gas reservoir like tight gas reservoir.
