摘要
目前在复杂岩性地层测井解释中,判别岩性主要采用交会图技术。交会图方法考虑的岩性比较简单,参数选择不当,就会出现错误的结果。本文提出用“模型的概率”来选择岩性组合或解释模型。通过实际资料处理验证该方法解释结果,与取心分析对比符合较好。该方法已编成软件,并可加入到现有各种测井解释软件中。
At present,the main method for lithology determination from logs in formations with complex lithologies is crossplot. Since the lithologies and minerals considered in crossplot are simple,if selected paameters are not pertinent,erroneous results will occur. This paper describes a new method using model probabilily to select lithology combination or interpretation model. Practical log processing shows that results by the new method concide well with that from core analysis. The software of the new method has been developed and integrated into other log interpretation software to put into use.
