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 resolution. The method is based on fl attening events in instantaneous phase to compare the seismic traces to the well log traces with the same phase. We calculate the coeffi cients using the singular value decomposition method to extrapolate the well logs. As a result, the events in the seismic profi le are continuous and match well with well logs. We apply this method to the Mao-2 well in Daqing Oilfi eld with good results.
