应用中值滤波实现合成地震道与实际地震道匹配

Application of Median Filtering to Realizing the Match between Synthetic and Actual Seismic Filtering Trace

在地震勘探中，声波测井速度和地震资料处理中得到的速度是两个非常重要的参数，但两者之间存在一定的差异。本文提出用中值滤波技术对声波测井数据进行处理，能消除合成地震道与井旁地震道间的差异，使两者之间建立很好的匹配关系．

It is different to compare the sonic logging velocity with the velocity from processing seismic data.This paper presents the logging data,it can despels deference betwcen synthetic and actual seismic tface near a well, thereby setting up their better match relationship.
