Abstract：We give a method for synthesizing borehole-side 2D seismogram with the useof dip log,acoustic log and density log data-The method consists of the followingsteps:·The acoustic impedance curve that is derived from acoustic log and densitylog curves is taken as a basic trace.·According to formation dip and CDP interval,two traces are extrapolated atthe each side of the basic trace to form a five~trace geological model.·Borehole-side 2D synthetic seismograms are produced by making convolutionafter fault and unconformity are revised carefully.Compared with one-dimensiona1 synthetic seismogram,the borehole side 2Dsynthetic seismograms have the following superiorities:1)added dip,fault and un-conformity informations,and 2)irnproved correlation between drilling data andseismic section.This method was applied to exploratory borehole data in faultedbasin in Daqing area,with satisfactory result.
