AUTOMATIC FORMATION DIVISION AND LITHOLOGIC INTERpRETATION BY LOGGING USING COMpUTER

Based on the preprocessing of logging data such as format conversion,environment impact correction,smoothing filter,standardization and weighting,the automatic formation division is conducted by the system weighted generalized curve information method and curve activity analysis method,and the automatic lithologic interpretation is realized by the probability statistic method and cluster analysis method,a complete computer interpretation system of logging data is formed.
