一、引言速度分析是地震勘探数字处理的一项重要内容,因为只有获得准确且数量足够多的速度资料,才能成功地进行水平迭加,偏移迭加乃至直接找油气的“亮点”处理等工作。自动速度分析是速度分析的一个新方法。它能获得连片的速度资料(或一条测线上的速度资料),兼有质量可靠、处理速度快、自动化程度较高等优点,目前在国外得到了较多的应用。 I. INTRODUCTION Speed ​​analysis is an important part of seismic digital processing because it is only by obtaining accurate and sufficient velocity data that horizontal stacking, offset stacking and even direct “spotting” of oil and gas can be successfully performed jobs. Automatic speed analysis is a new method of speed analysis. It can get contiguous speed data (or a line speed data), both reliable, fast processing, high degree of automation advantages, at present has been more abroad.
