| 摘 要： | 利用动态规划算法进行有序序列匹配来识别地质标志层位,在选取特征模式参数时,不仅考虑了曲线形态的特征,而且考虑了地层岩性的特征。对特征模式向量进行了量纲一致性处理。识别时既可以对全孔所有层识别,也可以只做部分层位识别,还可以分段识别。对山东唐口地区的几口井做了识别处理,均取得较满意的结果。

| Abstract: | The ordered series matching method by using dynamic programming algorithm is discussed in this paper for recognision of geologic key beds in borehole by well logs. Not only the characteristics of log shape, but also the lithological properties are used for the selection of the pattern parameters, which are processed with the normlization. The window and interactive mode are used in the software developed for this method. All strata in whole well can be recognized, as well as the partial strata or sections of a well during the software running. A test of method and software has been done from several wells in Tangkou, Shandong and shown the satisfied results. |
