注淡水开发层状油田水驱实验研究

Laboratorg Experiment upon Laminated Fresh Water Flooded Reservoir.

魏斌，刘凤亮，刘荣等．注淡水开发层状油田水驱实验研究．测井技术，１９９９，２３（４）：２４９～２５２选取注淡水开发层状油田高含水期密闭检查井岩心，开展储层条件下水驱油实验。运用储层流体流动单元的概念，研究不同流动单元中电阻率、含水率、相对渗透率与含水（油）饱和度之间的关系及变化规律，取得了一些新的认识。对该类油田水淹规律的认识、剩余油饱和度解释都具有重要的意义。

sing the cores from sealed observation well drilled through laminated fresh water flooded reservoir with high water cut, water displacement test under reservoir conditions is implemented. Based on the concept of fluid flow unit, the relationship among resistivity, water cut, relative permeability and water/oil saturation in different flow units and its changing law are studied. Some new viewpoints are obtained. These viewpoints are of great importance to have a good knowledge of the similar wateredout fields and the quantitative interpretation of remaining oil saturation.
