摘要
核磁共振测井通过提供总孔隙度、自由流体孔隙度、束缚水孔隙度、渗透率和岩石的孔径分布等重要信息，具有受岩石骨架的影响较小的优势，在准确进行储层评价及识别流体等方面都有很好的应用效果。应用核磁共振测并发现了大量低电阻率油气层，对复杂储层孔隙参数的确定等方面也具有常规测井无法比拟的优势。二维核磁共振技术的初步应用展示了核磁共振测井在油藏评价中的广阔前景。
Nuclear magnetic resonance(NMR)logging,providing important information such as total porosity,free fluid porosity,bound water porosity, permeability and pore size distribution,etc.,can be used to evaluate reservoirs and identify fluids accurately because it is affected less by rock matrix.A lot of low-resistivity hydrocarbon reservoirs have been discovered by using NMR.It has more advantages in determination of complex pore parameters which conventional logging methods cannot compare with.Primary application of 20D NMR technique shows its extensive prospect in oil reservoir evaluation.
