Abstract:The synthetic seismogram derived from deviated well logging trace can not be used to make stratigraphic division along the deviated well. It may be applied to stratigraphic division for the vertical seismic trace at the head of the deviated well;however, great error occurs in such stratigraphic division because of bed dip influence. It is necessary, therefore, to make dip and depth corrections of the deviated well logging trace so as to obtain a ‘pseudo’ logging trace which reflects the petrophysical property of a vertical seismic trace at the well head. Then the ‘pseudo’vertical logging trace is used to produce synthetic seismogram that can be used to perform stratigraphic division for vertical seismic trace at the well head. The example shows that the stratigraphic division using this method is reliable. This method is applicable for the area in which geological structure is simple.
