摘　　要：岩性记录在地震地质信息中具有直观和相对准确的特点。在层位标定过程中,为了充分发挥岩性记录的这些特点,并使得合成地震记录的标定更趋准确合理,可利用合成地震记录所生成的时间-深度关系表或直接利用声波测井数据计算所得到的时-深关系,将岩性录井数据转换到时间域下,能更好地体现地震相—测井相—地质相的"三相"结合。该方法满足了在生成反演阻抗体之前以快速简便的方式提高地震地层学解释精度的需要,同时对提高地震层序边界划定的准确性起到了辅助作用。实际应用证明该方法简单实用有效。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.
