This paper studies the NMR characteristics, the NMR porosity, the movable fluid T_2cutoff and other NMR properties of the shale rock sample. The experimental results demonstrate that the shale T₂ spectrum can be divided into three types, the single peak T₂ spectrum, the two peak T₂ spectrum containing one isolated right peak and the two peak T₂ spectrum containing continuous left and right peaks. The T₂ relaxation of the shale is mostly less than 10ms. The fracture porosity is only about 9.16% of the total pore space. The surface area per unit volume of the shale gas reservoir ranges mainly from 3.59 to 80.51μm^-1. The shale NMR porosity is generally less than its conventional porosity. The average error is about 22.33%. The movable fluid T_2cutoff value is in the range from 3.87 to 16.68ms and its average value is 8.29ms. The free gas saturation of the shale gas reservoir obtained from the centrifugal experiment is about 9.72%., authors=SUN Junchang¹, CHEN Jingping², YANG Zhengming^1,3, LIU Xuewei³, LIU Yuanjun⁴, authorsList=SUN Junchang;CHEN Jingping;YANG Zhengming;LIU Xuewei;LIU Yuanjun, authorCompany=1.

articleAbstract=系统研究致密页岩储层核磁共振响应特征对于将核磁共振技术应用于该类油气资源开发具有重要的基础指导作用。综合使用核磁共振、气水离心等实验技术研究了页岩核磁共振T₂谱响应特征、核磁孔隙度、可动流体T₂截止值及岩石比表面分布等储层特征。研究结果表明,页岩T₂谱可以分为3种类型,即单峰T₂谱、含有孤立右峰的双峰T₂谱及左、右峰连续分布的双峰态T₂谱,页岩绝大多数T₂弛豫时间小于10ms,储层中裂缝孔隙约占总孔隙空间的9.16%。基于核磁共振T₂谱计算的页岩比表面主要分布在3.59—80.51μm^-1。页岩核磁孔隙度普遍小于水测孔隙度,平均误差约为22.33%,其与黏土孔隙、裂缝孔隙发育等因素有关。结合气水离心实验结果,计算得到页岩储层核磁共振可动流体T₂截止值分布在3.87—16.68ms,平均值为8.29ms,储层基质岩石游离气饱和度平均值约为9.72%。,
