基于核磁共振测井的W区块水淹层评价方法研究

Evaluation of flooded water layer in W region based on NMR logging

论文以W地区长C储层为研究对象,在测井资料、岩心实验资料分析的基础上,基于核磁共振测井资料解释数据,研发了以毛管大孔径孔隙、地层总孔隙度、渗透率为变量的水淹层判别模型。该方法开拓了W地区C储层利用核磁共振资料判别水淹层的新途径。应用效果分析表明,该方法能有效识别水淹层,应用效果良好。

Chang C reservoir in W region was investigated on the basis of data analysis on logging and core experiment as well as on nuclear magnetic resonance(NMR)logging interpretation to establish the discriminant model of watered layer with porosity of wide aperture capillary,formation porosity and permeability as variables.This method explores new way of discriminating flooded reservoir layer via NMR data.Application effect analysis shows that this method can effectively identify water flooded layer with good results.
