辽河油田中低电阻率油层解释评价方法研究

随着油田勘探开发的深入，充分认识和研究中低电阻率油气层解释评价方法，已成为石油地质工作者攻关的重要课题之一。针对中低电阻率油气层的特征。分析了辽河油田中低电阻率油气层的形成原因及其在录井中的显示特征，对应用定量荧光录井参数、气测与地化参数结合及核磁共振录井参数解释方法进行了研究，建立了定量荧光录井参数、气测与地化参数、核磁共振录井参数解释评价图板及标准，形成了一套系统的现场快速评价方法，通过实例说明录井新技术在辽河油田中低电阻率油气层解释评价中的显著效果，为该油田现场储集层解释评价研究奠定了基础。

Study on interpretation and evaluation method for the medium-low resistivity oil and gas layer in Liaohe Oilfield

With the deepgoing of the oilfield exploration and de- velopment,fully recognizing and studying the interpretation and evaluation method for the medium-low resistivity oil and gas layer has become one of the key subjects for petro- leum geologists.According to the characteristics of the me- dium-low resistivity oil and gas layer,the paper analyzed its forming and displaying feature during mud logging,studied the interpretation method of the combination of quantitative fluorescence logging parameters with gas logging,geochem- ical and nuclear magnetic resonance logging parameters,es- tablished the interpretation chart and standard of the quanti- tative fluorescence logging parameters with gas logging,ge- ochemical parameters and nuclear magnetic resonance log- ging parameters,and formed a set of systematic fast evalua- tion method on wellsite.It was proved by the practical use that the new mud logging technology had got remarkable effects in the interpretation and evaluation for the medium- low resistivity oil and gas layer in Liaohe Oilfield and pro- vided bases for wellsite reservoir interpretation and evalua- tion of the oilfield.
