| 摘 要： | 经过多年的注水开发,L地区水淹层状况复杂多变,使用常规测井解释方法识别水淹层具有很大困难,而基于PCA(主成分分析)的贝叶斯判别法要求测井数据符合正态分布,但是L地区测井数据有限,因此判别的正确率不高.为此,根据测井资料,运用基于PCA的模糊综合判别法建立解释模型来进行水淹级别的预测,用建立的模型处理了22口井,与试油...

| Abstract: | For many years of waterflooding,the situation of water-out reservoirs was complicated in L Area,it was difficult for identifying water flooded reservoirs with conventional logging interpretation methods.And Bayes discriminant method based on principal component analysis required that logging data should accord with normal distribution,but the logging data of L Area were limited,thus the discriminant accuracy was not high.Therefore according to the logging data,fuzzy synthetic discrimination based on princip... |
