| Abstract: | Some typical core NMR experimental examples from Liaohe Oilfield are presented in this paper,such as NMR porosity measurements with diverse echo time, T 2cutoff distribution of cores with different lithologies, irreducible water saturation computed from T 2 geometric mean model,NMR permeability calculated from different models,and T 2 distribution measurements through changing T E and T W under the conditions of various water saturations. Some significant conclusions from these core NMR experiments are contributed to both NMR log data acquisition and processing. |
