利用零偏垂直地震剖面资料,可以增强井底总深度之下的地质构造预测能力。在这种情况下利用VSP资料的关键就是分辨率和延伸观测距离。波阻抗测井曲线是利用VSP资料进行延伸观测时最有效的工具。VSP综合地震道必须首先与地震剖面和测井合成记录准确连接。通过VSP综合地震道反演可获得波阻抗测井曲
Using the data of the vertical deviational vertical section, the ability of predicting the geological structure under the total depth of the bottom hole can be enhanced. The key to using VSP data in this situation is resolution and extended viewing distance. Wave impedance logs are the most effective tools for extending observations using VSP data. VSP Synthetic Seismograms must first be accurately linked to seismic profiles and well log records. Wave impedance logging is obtained by VSP integrated seismic trace inversion
