备注

论述了昆明盆地中深层地震勘探剖面的特殊处理方法,主要采用针对断层及沉积地层较为敏感有效的波阻抗反演、层速度反演、瞬时相位、瞬时频率、瞬时振幅以及二维相干等几种处理手段以及基于此的断层分析,给出了昆明盆地内主要断裂的参数。

We introduce special methods for processing the reflection exploring data of Kunming Basin,wave resistance,interval velocity,instantaneous attributes and 2D coherence inversions,which are effective to fault and sedimentary stratum.Base on these inversions,we give the main faults in Kunming Basin.
