摘要
渗透率是表征储层渗流特性的主要参数之一,大量的测井和实验表明,核磁共振测井能较好地表征岩石的孔隙结构。因此,核磁共振测井成为与渗流机理最为接近的测井方法。本文分析了核磁共振测井测量渗透率的原理,各种模型的比较,核磁共振测井求取渗透率的影响因素。
Permeability is one of the major parameters to describe reservoir seepage characteristics.Plenty of logging and experiments indicate that nuclear magnetic resonance(NMR) logging can characterize pore structure of rocks.Therefore,NMR logging became a logging method which is very close to the seepage mechanism.In the paper,the measurement principle of NMR logging is analyzed and also comparison of various models,influencing factors in calculating permeability with NMR logging.
