摘要
应用逐步判别分析数学原理,在松辽盆地东南隆起区建立了一种新型的利用气测录井资料定量判别油、气、水层的方法,即七参数判别法.应用该方法判别油、气、水层,平均符合率达82.3%,提高了该地区油、气、水层定量判别的水平;并且,在荧光录井很难识别的气层、凝析油层等疑难层的判别上取得了较大突破,对现场快速识别油、气、水层方法研究是有益的探索.
With the help of progressive discriminant mathematics, a new method of 7_parameter discrimination is developed for the Southeast Uplift area, Songliao Basin, which can identify quantitatively oil_, gas_and water_bearing layers by using gas logging data. This method has achieved an average accuracy of 82.5%, resulting in much improvement in discrimination of oil_, gas_and water_bearing layers for the area. In addition, a greater breakthrough has been reached in identifying obscure gas_ and condensate_bearing layers that are difficult to be recognized by fluorescence logging, which is helpful attempt to rapid identify oil?, gas_and water_bearing layers on drilling site.
