【摘要】 对亲水岩心吸吮过程中油相的捕集规律进行了考察.以随机毛管束物理模型为基础,建立了应用压汞毛管力曲线计算油水两相吸吮相对渗透率的数学模型.对该模型进行了试验验证,同时与M.B standing模型作了对比.结果表明,应用压汞资料计算油水吸吮相对渗透率曲线的方法是可行的.更多还原

【Abstract】 The trapping of oil-phase during water flooding for water-wetted core was studied experimentally. A model for calculating oil-water relative permeability was established by using mercury capillary pressure data for a strongly water-wetted system. The calculation result was compared with those of the experiment and the M. B. Standing model. It was proved that the calculation of oil-water imbibition relative permeability by using mercury capillary pressure data was feasible.更多还原
