Abstract：Calibrating the geological horizon of seismic profiles by VSP and synthetic records,which has plenty of well-studied methods and well-established standards,is a critical step in conventional seismic data interpretation. However,the method of calibrating the geological horizon of single-shot records has rarely been explored. Generally,the quality of single-shot records is measured by the "phase surface method" in the field of seismic data acquisition, but this method fails to provide a clear picture of the geological horizon corresponding to the event in the reflection layer of single-shot records,which affects the scientific and rational qua-lity evaluation of single-shot records. Considering this,we propose building the four-dimensional seismic data volume of "the figure of buried time T0u, geological horizon,topography,and source coordinates" and applying an intelligent method that instantly calibrates the geological horizon of each single-shot record. In other words, by the recor-ding geometry for seismic data acquisition, the computer automatically outputs the single-shot record with its geological horizon as each shot is explo-ded. The proposed method is conducive to analyzing the reflected energy and signal-to-noise ratio in the target layer, achieving a real-time response in che-cking the quality of each single-shot record,and thus ensuring that high-quality seismic data can be acquired.
