| 摘 要： | 采用比较热门和精确的心迹线法实现利用地震VSP资料进行Q值反演。通过实例验算,证实了这种方法的可行性和有效性。在反演过程中,该方法对超过350 m的厚层反演效果较为准确,对薄层其反演效果不稳定,但总体趋势不会有大的变化。

| Abstract: | This paper runned the Q-factor inversion according to seismic VSP(vertical seismic profile) data and the centroid method which is comparatively prevalent and precise.It is validated by the examples,the feasibility and validity of this method has been demonstrated.Study on the inversion process,The method for over 350 inversion effect of thick layer is comparatively precise,meanwhile for inversion effect of thin layer is relatively unsteady.but trend of collectivity change slightly. |
