摘要
本文以塔木察格盆地主力油层查干组储层具有砂砾岩、凝灰质砂砾岩等复杂岩性的地质特征为基础，并以钻井取心及岩心薄片分析资料为依据，将岩性划分为5大类，在此基础上分析总结每种岩性测井响应特征，从定性上实现了岩性的有效识别；另外，为能利用多条测井曲线进行识别，而避免分析问题的难度和复杂性，采用先对测井曲线数据进行主成分析，然后利用K-均值聚类的方法实现岩性的定量化识别，经实际资料验证，见到较好的应用效果，进而为下一步油藏描述和油田开发提供必要的保证。
The lithology in Tsagaantsav formation of Tamtsag basin can be divided into 5 kinds on the basis of geologic features of the complex litholo- gy and coring analysis data.The logging response characteristics of each lithology are used to identify lithology qualitatively.In order to avoid analysis difficulty and complexity with multiple logging curves,the logging data are analyzed first,then K-average-value cluster method is used to identify the hthology quantitatively.Practice has showed that it is effective and can provide necessary assurance for further reservoir description and oilfield development.
