随着地震勘探技术的发展，要求构造图的精度越来越高．本文阐述了一套利用地震解释工作站进行人机交互速度解释的方法，该方法主要包括叠加速度谱的精确选取，界面平均速度的交互平差，利用钻井、测井资料对界面平均速度进行校正，使解释员的地质认识和速度解释相结合，能够得出符合地质规律的平均速度，提高了深度图成图精度，是一套行之有效的速度解释方法。 With the development of seismic exploration technology, the accuracy of the structure drawings is required to be higher and higher. In this paper, a set of methods for interpreting human-computer interaction velocity using seismic interpretation workstation is described. The method mainly includes the precise selection of superimposed velocity spectrum, the interaction adjustment of average velocity of interface, the correction of average interface velocity by drilling and logging data, By combining the interpreter’s geologic understanding with the speed explanation, the average speed in conformity with the geology rule can be drawn and the mapping accuracy of the depth map can be improved. This is an effective way to explain the speed.
