Abstract：Seismic slice(horizontal slice,stratigraphic slice and stratal slice) technique is a widely used means in seismic interpretation,however the time-crossing phenomenon was sometimes developed under complicated geology conditions.According to the predecessor's understanding for the phenomenon,and based on the basic assumption on which the seismic events are the basic isochronous stratum unit and by strictly following the occurrence changing trends of the seismic events the true stratal slices were acquired by applying automatic tracking technique which is based on dip control body.Based on the slices and by combining geological characteristics and seismic response characteristics,the accurate isochronous stratigraphic framework of the target layers were established,the sub-layer correlation and classification inside the reservoir,the vertical structure changing and lateral distribution analysis were conducted,the excellent results were achieved in the research.
