Integrated horizon calibration by combining the seismic and geologic and its application

Among seismic and geologic information,lithologic record is visual and comparatively accurate.In order to bring the characteristics into full play and make the cali- bration more reasonable,the time-depth table generated from integrated synthetic seismogram or time-depth con- version calculated by acoustic logging data should be uti- lized.Therefore,the lithologic logging data can be changed into time domain which combines seismic facies, logging facies and geologic facies together.The method enhances the interpretation accuracy of seismic-strati- graphic data before inversion and improves the premise of identifying sequence boundary at the same time.The ap- plication results prove it is a simple and effective way.
