摘　　要：针对吐哈油田储层地质特征复杂、非均质性强,而现有测井解释模型建立方法忽略了储层特性上的差异性,使得测井解释模型与油田实际的地质情况相差较远的问题,以吐哈油田为研究对象,综合考虑沉积微相控制下的储层在岩性、物性上的变化,依据测井相模型,在进行关键井检验的基础上,分层系和沉积微相分别建立储层参数解释模型。利用测井资料以及测井计算的储层参数,应用贝叶斯多总体判别分析的方法,分层系建立油、水、干层识别的解释模型,进行测井解释工作,得到的测井解释结果与油田实际生产资料吻合度高,为测井储层评价提供了有力的数据基础。The geological characteristics of Tuha is complex and strong heterogeneity, and the existing logging interpretation model estab-lishment method ignores the differences of reservoir characteristics of the logging interpretation model of non wide applicability, accuracy is not high,and the actual geological conditions of oil is far away. Taking the Tuha oilfield as the research object,considering the reser-voir under the control of sedimentary microfacies changes in lithology, physical properties, logging facies model based on the test of key wells, interpretation model of reservoir parameters were established according to the different strata and sedimentary microfacies. The reservoir parameters were calculated by using logging data and well logging, oil-water layer identification dry interpretation model was established by using Bayesian discriminant analysis method,log interpretation was also carried out. It was shown that,the interpretation results and actual oil production data match well, and the data provide a strong foundation for the reservoir evaluation.
