摘　　要：从第85届美国SEG年会的会议论文中,遴选了34篇具有一定代表性的、涉及地震各向异性理论和多分量地震技术,主要包括基础实验理论、应用效果,或在多分量地震数据的处理和多波的解释反演方法技术方面体现了一定先进性的文章进行逐一剖析,并对各向异性岩石物理实验和基础理论模型、多分量地震数据处理的关键技术、海洋多分量地震、矢量场技术给予重点介绍。伴随世界油气价格的持续低迷,尽管逆时偏移和全波形反演沿袭前几年的热度仍在本届年会学术报告中占据了一定的比例,但毫无疑问,本届年会的特点主要是转换波处理的难点攻关、海洋多分量地震的双检压噪和应用,所呈现的潜在发展态势是:随着地震观测技术的发展,微震与时移地震的联合应用、地震与电磁的联合观测、6分量矢量场的观测和利用可能会成为以后领域发展的主流。About 34 papers are chosen and analyzed from the 85th SEG technical presentations, of which, some are about rock physics and basic theories of anisotropy, some present plausible applications and case studies, some about key techniques on processing, inter- pretation and inversion of multi-component and multi-wave.Special emphasizes are given to the papers that might proceed the knowledge of anisotropy and principle models ,or make progress on key technique of multi-component seismic data processing, besides ocean 4-C seismic and vector techniques.Effected by the lower price of oil worldwide through years, it is obviously that the most advances are about PS-statics correction,dual sensors denoising and 4C application in marine field, though papers about reverse time migration and full wave inversion still occupy a certain ratio,just because they had been the main roles in the past years.It would be predicted that, promo- ted by sensing techniques and seismic applications ,joint application of micro- and time-lapse seismic prospecting based on multi-compo- nent, acquirement of seismic and electromagnetic data at the same position, and 6-component seismic measurement and utilization will be the spot lights in the future.
