【摘要】 本文通过在饱和度方程中引入与岩石性质有关的岩性系数a,发展了原三水模型,更加突出了三水模型在解决低孔低渗储层中的优势。新三水模型在比较全面地概括岩石几种不同导电机理的同时,也考虑了岩石性质的影响。将此模型应用于腰英台油田的低孔低渗储层和砂泥岩地层中,取得了较好的效果。更多还原

【Abstract】 By introducing lithological coefficient a which is related to rock’s properties in saturation equation,the original three-water conduction model was developed,so the three-water conduction model’s advantage in description of low porosity and low permeability was highlighted.While the new three-water conduction model generally summarizes different conductive mechanism for rock,it considers the impacts from the rock properties.When the model was applied in low porosity and low permeability reservoir and sand-shale strata,great application effects were achieved.更多还原
