  1. The above data are the thickness-weighted average values of the logging parameters of the main target horizon. SP is the spontaneous potential logging curve, GR is the natural gamma logging curve, RT is the resistivity logging curve, AC is the acoustic transit time logging curve, DEN is the density logging curve, PE is the photoelectric cross-section index; SH is the shale content.
