摘要
VSP time-depth relationship often needs to be adjusted when comparing with migration section.Taking the theoretic time-depth relationship as the standard,this paper analyzes the difference between VSP and migration section with theoretic time-depth relationship based on the comparison.Comparing actual VSP measured data in CYQ structure of Bohai Oilfield with VSP forward modeling result,this thesis analyzes effects of VSP and migration section on the time-depth calibration in tilted stratum.
