摘　　要：塔里木盆地孔雀河地区纵、横向地层和岩性差异较大,造成速度变化大,传统的常规速度分析方法已不能满足构造研究的精度要求。综合利用地震、地质、测井等资料,采用“Dix公式和射线追踪法”相结合, 建立空间速度场,取得了较好的应用效果。Speed parameter of seismic wave is a key factor in seismic exploration, which can provide valuable information about subsurface structure and lithologic characteristics. Therefore obtaining accurate speed parameter is very important for seismic processing and interpretation, which is closely related with the successful process of exploration. However, normal speed analysis can not satisfy the accurate requirement of structure research because of the speed variance caused by the difference of lithologic characteristics as well as transversal & longitudinal formations in kongquehe block With the comprehensive use of seismic, geologic and logging data and adopting the combination of 'Dix formula and ray tracing', spacing speed field was constructed, which has received encouraging results.
