摘要: VSP(垂直地震剖面)资料是连结钻井资料和地面地震剖面的天然桥梁,合成记录只能做参考。了解VSP资料和地面地震剖面在记录方式、基准面选择、低降速带校正方法以及资料处理过程是用好VSP资料、做好层位标定的前提。

Abstract: VSP data can act as medium of synthesizing drilling data and seismic profile. Composite seismogram can only be used as reference. Hence, to understand the record mode, datum-level selection, weathering and sub-weathering correction method and data processing of VSP data and seismic profile are prerequisites for well utilizing VSP data and horizon calibrations.

Key words: VSP corridor stack, horizon calibration, weathering and sub-weathering correction, synthetic seismogram, average speed, stacking speed, datum level
