摘要
有效地分离上行波和下行波是VSP资料处理的一项基本任务,为了得到径向R分量和切向T分量的波场还要首先要对水平分量记录进行坐标旋转。本文介绍了三维VSP坐标旋转理论和中值滤波方法,并用该方法对理论模型及实际数据进行上下行波波场分离处理,得到的较好的分离效果表明选择正确方法的重要性。
The separation of up and down-going wave is a basic task in VSP data procession. It is necessary to orientation determination and correction of horizontal component for getting radial direction R and tangential direction T. The article introduces the theory of coordinate rotation and the methods of median filter, and finally the author processes the theoretical record and actual data using them. The better processing results has verified the validity and importance of selecting correct coordinate rotation theory and wavefield separation method.
