摘要
Seismic data could not be used to correlate subzones in a nonmarine reservoir，in general, as a result of the limitation of the vertical resolution. Because the major seismic reflections have chronostratigraphic significance, and the isochronic correlation is relative, the seismic data may help us to correlate subzones of a non-marine reservoir under certain conditions. The authors generalized the basic rules for isochronic correlation by using seismic reflection profile in the SZ36-1 oil field. Isochronal horizons can be obtained through recognizing types of seismic unconformity boundary, the features of seismic facies and the relations of sandbody overlapping.
