摘要
气测录井中色谱组分出峰不全时,目前还没有较好的定量解释方法。本文根据Fish-er判别准则,提出了建立数学模型进行气测解释的新方法。这种方法已在辽河断陷使用两年多,实践证明,它对稠油层,气层、含油水层、干层都能较好的判别,实判符合率为85.6%。本方法提高了解释符合率,对促进油田的勘探开发起到了良好的作用.
There is no better quantitative interpretation method when not all chromatographic peaks are absent in gas logging. The paper presents a new gas logging interpretation method which has been tested in Liaohe rift by establishing mathematical model based on Fisher discriminant criterion . It is suitable for formations of viscous oil, gas, oil bearing aquifer and dry, the real coincidence rate is up to 85. 6%.
