| 摘 要： | 针对VSP时深关系与偏移剖面对比时经常需要进行调整的情况,本文以理论时深关系为标准,通过VSP时深关系、偏移剖面与理论时深关系的对比研究,分析了VSP、偏移剖面与理论时深关系的差别所在。以渤海油田CYQ构造已钻井实测VSP数据和VSP正演结果为实例对比分析了倾斜地层VSP和偏移剖面对时深标定的影响。

| Abstract: | 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. |

| Keywords: | time-depth relationship VSP migration section forward modeling time-depth calibration tilted stratum |
