在人造均质物理模型上模拟大庆油田储层条件,研究水驱和聚合物驱油规律,探讨有关提高原油采收率方法及强化采油的可行性。从中得出人造物理模型的水驱油效率与油水粘度比及空气渗透率之间的相关经验公式。
This paper simulates the reservoir conditions of Daqing Oilfield on man-made homogeneous physical model, studies the law of water flooding and polymer flooding, and discusses the feasibility of enhancing oil recovery rate and enhancing oil recovery. The empirical formula between the water flooding efficiency and the oil-water viscosity ratio and the air permeability of the artificial physical model is obtained.
