摘要
本文采用数值模拟并结合物理模拟两种手段对生物聚台物溶液中悬浮微粒的驱油渗流动态进行了探讨。物理实验发现,所用的生物聚合物溶液中的悬浮微粒在多孔介质中进行运移,并被捕集,因而引起溶液在介质中的渗透率显著下降。作者根据 C—H简化模型及物理模拟实验模型,建立了一套简单的数学模型,通过数值计算方法对所要分析的堵塞情况进行了数值模拟,从而对生物聚合物溶液中悬浮微粒在驱油过程的渗流规律进行了探讨。
By means of physical and numerical simulation,this paper studies the kinetic process of oil displacement by suspended particles in biopolymer solution.The suspended particles in biopolymer solution,when moving through the porous media,are captured by the latter,which reduces remark— ably the solution permeability through the media.In the light of the Corapoioglu-Haridas simplified model and the simulated physical experi- mental model,a set of mathematical models are established to simulate numerically the clogging by way of numerical calculation.Thus,the flow law of the suspended particles in biopolymer solution through porous media is formulated.
