摘要
应用多组逐步判别分析方法原理,结合测井、录井、完井测试等资料的气、水显示情况,选取鄂尔多斯盆地北部某气藏典型井建立该地区气、水层的判别模型,以便对该地区单井进行气、水层划分。在建立初步判识模型后,应用回判率检验、F检验等方法对模型的显著性进行检验,其判别气、水层的平均符合率达到95.48%,表明所建立的模型是可靠的,能够比较准确地判识该地区的气、水层。
Based on the showing of gas and water in well logging, well recording and well testing, this paper uses the step discriminant analysis to establish the discrimination model of gas and water in a certain gas pool in north of Ordos basin in order to mark off the gas and water in single wells in this area. After the primary discrimination model is established, the methods of return discrimination test and F test are adopted to verify its significance. The result shows that the average exact probability reaching 95.48 percent. This indicates that the model is creditable, and can heighten the level of identifying gas and water in this area.
