关 键 词：events flattening SVD method instantaneous phase correlation 

摘      要：Based on a detailed analysis of differences between seismic data and well logs, we discuss the problem of matching seismic traces and well logs and present a new matching method based on event search in instantaneous phase which greatly improves seismic *** method is based on flattening events in instantaneous phase to compare the seismic traces to the well log traces with the same *** calculate the coefficients using the singular value decomposition method to extrapolate the well *** a result,the events in the seismic profile are continuous and match well with well *** apply this method to the Mao-2 well in Daqing Oilfield with good results.
