体约束多界面重力反演方法与应用

GRAVITY INVERSION METHOD AND ITS APPLICATION IN THE CONDITIONS OF VOLUMETRIC RESTRAINT AND MULTI-INTERFACE

为解决地震勘探中因特殊地貌所造成的地震资料空白区问题，本文利用重叠的地震资料作为已知条件，对重力资料进行体约束多界面反演，并将反演结果镶嵌到地震资料的空白区内。此方法精度高，实际应用效果好。

For resolving the problem of seismic data blank area resulting from special ground features in seismic exploration, the paper takes the overlap seismic data as the known conditions, then makes the gravity data inversion of volumetric restraint and multi-interface. And furthermore, the paper inserts the inversed results into the blank area of seismic data. The accuracy of this method is much higher and the effects of actual application are much better .
