Application and correction of logging technology in mineral exploration
The depth error of logging is a long-term factor that seriously affects the quality of logging.By correcting the depth of the cable of logging winch,the influence of cable on logging depth can be effectively reduced or eliminated.The dual-depth system method and marker layer method are used to correct the cable depth,which is more time and labor saving and has higher accuracy than the traditional manual measurement method.At the same time,the gamma log curve obtained by using the corrected parameters to correct the logging depth is in good agreement with the actual geological geophysical records.
