塔里木盆地孔雀河地区速度场建立及应用探讨
|
摘要
速度研究及应用是地震勘探永恒的话题。孔雀河地区由于纵、横向地层、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,因此,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,得到了较好的应用效果。
The study of velocity and its application is a hot topic in seismic exploration domain. Due to obvious vertical and lateral changes of stratigraphic sequences and lithology in Kongquehe area, the seismic velocity is greatly changed. The conventional analysis of velocity can't satisfy the requirement of accuracy of structural interpretation. The integration of seismic, geological and log data, with "Dix formula and radial track", the space velocity filed is established and a application effect is reached.
