摘要
速度建场的精度是制约复杂构造区成图精度的关键因素.针对山地构造复杂、地震资料品质差、叠加速度谱可信度低等问题提出了相应的解决办法.其中,层速度曲线绘制技术、曲线轨迹计算层速度技术、盐层速度建场技术等具有一定的创新性,在实际应用中取得了很好的效果,在复杂山地的变速成图中可以进一步推广使用.
The accuracy of velocity field is key factors of variable velocity mapping in intricate structure area. In this paper, We put forward the new technique of building velocity field to resolve difficulties in complex structures of mountainous area in which The character of seismic data is very bad and The reliability of Stacking velocity spectrum is too low to be directly built velocity field .the technique in this paper, for instance, the technique of velocity curve plotting, the technique of calculating interval velocity by curve locus and the technique of building salt-bed velocity field, is unparalleled and is very successful in practical application .the new method that have improved the precision of building velocity field should be farther spreaded in variable velocity mapping in intricate structure area.
