摘要
山区地震资料进行常规静校正时,校正误差随炮检距的增大而增大。受地形影响共中心点道集内反射点很分散,常规处理后空间分辨率大大降低。采用浮动基准面DMO叠加方法可以很好地解决这些问题。
When we conventional static correction for seismic data of mountain area, correction error increases along with the increases of source-detector distance. Be terrain influenced, reflection point in CMP gather are very dispersal. After conventional processing, the space resolution descend greatly. We can solve these problems by using method of floating datum DMO superposition.
