| 摘 要： | 松辽盆地北部深层火成岩地层岩性复杂，从基性到酸性火成岩均有出现，不仅有火山熔岩，也有火山喷发岩，对众多的火成岩样品所对应分析，依据对应分析结果，认识并选择出那些对识别火成岩岩性重要的测井曲线，总结了不同火成岩的测井响应特征，对58块火成岩样品的测井数据进行主因子分析，提取第一和第二主因子，依据第一和第二主因子的大小，用模糊聚类方法识别火成岩岩性，取得了较好的效果。 |

| Abstract: | The lithology of igneous formations in deep Northern Songliao basin is very complex.There are various igneous rocks from basic to acidic,not only volcanic lavas,but also eruptive tuffs. The log responses of various igneous rock samples are used for correspondence analysis(CA).The important logs which are sensitive to lithologic changes are recognized and the characteristics of log responses of igneous rocks are summarized according to the results of CA.After applying Principle Component Analysis (PCA) to the data of the igneous samples selected according to borehole condition,the first and second principle components from logs are obtained. The igneous rocks of this area are classified depending on the first and second principle components using fuzzy cluster analysis.The recognized lithology is comparable with cores. |
