A water flooding experiment was carried out with the real core and simulated oil without hydrogen. The water-oil two-phase fluid flow was studied using the technique of nuclear magnetic resonance, to obtain the distribution of irreducible water, irreducible oil and produced oil in cores of different porosity during drainage and imbibition, and to reveal the formation mechanism and imbibition mechanism quantitatively during the water displacement. The results show that the bigger the pore radius is, the lower the irreducible water saturation will be; the main reservoir space of low permeability reservoir is a medium with pores of more than 0.1 μm in radius; residual oil is mainly distributed in mid-small pores; and imbibition is significant in low permeability reservoir., authors=null, authorsList=null, authorCompany=1.

articleAbstract=低渗透岩芯孔喉细小，孔隙结构复杂，人造微观孔隙模型很难真实反映其微观孔隙结构。本研究利用真实岩芯，以去氢煤油为模拟油，利用核磁共振技术，研究了油水两相渗流规律，揭示了排驱和吸入过程的束缚水、残余油和采出油在不同孔隙中的分布，讨论了其形成机制，定量研究了驱替过程中渗吸作用的程度。结果表明，随着孔隙半径的增大，孔隙中束缚水饱和度逐渐降低，大于0.1 μm的孔隙空间是低渗透储层主要的储集空间，而残余油主要分布在中小孔隙，并且低渗透储层渗吸作用明显。本研究丰富了核磁共振技术在油田开发中的应用。, authors=王学武,杨正明,时宇,李海波, authorsList=王学武;杨正明;时宇;李海波, authorCompany=中国科学院渗流流体力学研究所, correspAuthors=null, authorNote=null,
