| Abstract: | In this paper, ridge regress method is used to handle well logs DLW, HG, HGG, DZW, and generate post-maps of rock character in the geo-physical well logs, the principle and method of ridge regress are introduced.The predict formula of rock character by studying of sample, computing results, and post-maps of rock character generated by computer are given. This method has practical meaning for interpretation of well log data by computer and automatic mapping. |
