| 摘 要： | 火成岩岩性识别是岩相划分、储层评价及开发方案编制的基础。针对火成岩岩石类型多、测井识别难度大问题,应用贝叶斯判别分析方法对火山碎屑岩测井解释中岩性识别问题进行研究。通过对样本集的优化处理和先验概率的应用,提高了识别率。应用该方法对海拉尔盆地乌尔逊凹陷乌东地区火山碎屑岩储层进行了岩性自动识别,符合率达到80%以上。

| Abstract: | Lithologic identification of the igneous rock is the base of rock phase dividing,synthetical reservoir evaluation and prognostication,pattern arrangement,development plan preparing.Because the type of igneous rock is more,it is very difficult to name and identify,we apply Bayesian discrimination to research lithologic identification in the logging interpretation of volcaniclastic rock.The technical key of the method is the foundation of sample set and prior probability.The text adopts Bayesian discrimination to carry through lithologic identification of the east of Urxun sag in Hailaer Basin which lies Daqing oil field periphery. |
