Abstract：We propose in the paper an automatic matching method of seismic and logging data in viscoelastic media for high accuracy time-depth curve in seismic calibration with logging data. In the view of the differences between logging and seismic observations, we analyze factors which affect matching synthetic seismogram and near-well seismic traces, and propose a method for automatically matching seismic and logging data in viscoelastic media. It includes the process of rough frequency matching, as well as fine frequency matching between them. This method can obtain precise phase velocity of seismic wave. Applications of the method in Kenly area, Shengli Oilfield prove its validity with good results.
