摘要
阐述了测井自动解释井剖面岩性的方法,应用聚类分析,结合岩心资料,建立标准岩性测井相数据库;应用BAYES多组二次逐步判别分析,分层解释井剖面岩性。对松辽盆地西部地区四口井进行了处理,解释符合率达80%以上。
The paper describes the method to determine automatically lithology from welllogs. The standard lithological electrofacies models have been established in the west ofSongliao Basin by clustering analysis of logging data and by comparison with core data.The lithological description is given by applying Bayes multigroup quadratic step-by-step discriminatory analysis. The interpretive results of four wells are good and over80% of the results is right compared with core data.
