摘要

本文研究出了M-N交会、微观结构识别、Bayes判别等3种复杂岩性测井划分方法,并建立了三分法孔-渗参数评价模型,使得油气层测井识别正确率由原来86.0%提升至92.5%,较好地解决了中原油田复杂岩性油气层的测井识别问题。
        Three complex lithology logging methods,including M-N intersection,microstructural identification and Bayes discrimination,have been formed by double calibration. Based on the evaluation models of porosity and permeability parameters in three-division-method,the corresponding criteria for reservoir identification are constructed. The accuracy of logging identification has increased from 86% to 92.5%,and the logging identification problem of complex lithological reservoir in Zhongyuan Oilfield is well solved.
