摘　　要：测井深度误差是一个长期存在且严重影响测井质量的一个因素,通过对测井绞车的电缆进行深度矫正,能够有效减少或消除电缆对测井深度的影响,采用双深度系统法及标志层法完成对电缆深度的矫正,相对于传统的人工丈量法更省时省力,其精度也更高,同时利用矫正后的修正参数对测井深度进行修正得到的γ测井曲线与实际地质物探编录情况相吻合。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.
