摘　　要：通过双标定,形成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,提出密度-深侧向电阻率重叠、核磁共振差移谱识别等2种油气层快速识别方法,基于三分法孔-渗参数评价模型,构建出相应的油气层判别标准,使得油气层测井识别正确率由原来86.0%提升至92.5%,能够准确识别复杂岩性油气层,较好地解决中原油田复杂岩性油气层的测井识别问题。In order to accurately identify complex lithological oil and gas reservoirs,three complex lithology logging methods,including M-N intersection,microstructural identification and Bayes discrimination,have been formed by double calibration.Two fleet identification methods of oil and gas reservoirs are proposed,such as the overlap of density and deep lateral resistivity and NMR spectrum identification.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.
