摘　　要：常规岩心分析有其不可避免的缺点，如测试时间长、昂贵、束缚水饱和度不可测量等，但核磁共振技术在解决上述问题的同时又具有不受岩样形状及取心方法的限制、精度高、参数获取多等特点。通过对长庆油田低渗透储层应用及研究．改进了核磁共振方法在低渗透储层中渗透率的计算公式，并分析低渗透储层可动流体与孔隙度、渗透率的关系．为低渗透油田开发提供了相关指导。The conventional core analysis has its inevitable shortcomings, such as the long test time, expensive cost, and unmeasured irreducible water saturation. The nuclear magnetic resonance （NMR） technique can solve these problems, at the same time it has characteristics of no restrictions of the rock shapes and coring methods, with high precision, and more obtained parameters. Application and research of them in low permeability reservoirs of Changqing 0ilfield improved the permeability calculation formula by the NMR method in low permeability reservoirs, and analyzed the relationship between the movable fluid and the porosity and permeability of low permeability reservoirs.
