摘要
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。
The demand for accuracy of structral maps become higher and higher with thedevelopment of seismic prospecting technology. In this paper a set of interactive velocityinterpretation methods using seismic interpretation workstation are expounded which mainlyinclude precise selection of stacking velocity spectra, interactive adjustment of interface averagevelocities, and correction of these velocities using drilling and logging data. Interpreters'geological knowledge is combined with the velocity interpretation and can obtain average velocitiesconforming to geological laws. The set of methods improve the accuracy of depth section mappingand are effective for velocity interpretation.
