为了模拟在微生物提高采收率过程中所包括的细菌传播、生长和代谢过程，以及预测由于细菌在孔隙介质中的活动而造成的渗透率改变，本文建立了一个一维、三相、多组分数学模型。在这个模型中引入了对流—弥散方程和微生物动力学方程，用以描述在MEOR过程中微生物体的产生、代谢产物的形成以及营养物的消耗与利用。模型假设由于微生物体在孔隙表面的滞留和在孔隙喉道的堵塞引起了渗透率的改变。为了验证该模型的适用性，进行了静态实验与岩芯驱替试验，将实验给果与数值模拟计算结果进行了比较＿结果表明该模型的确能够模拟实验的主要做生物动力学过程。将其推广可以用于微生物提高采收率现场试验设计、评价和效果预测。
In order to simulate the bacterial spread, growth and metabolic processes involved in microbial enhanced oil recovery and to predict changes in permeability due to bacterial activity in the pore medium, a one-dimensional, three-phase, multi-set Fractional model. In this model, the convection-dispersion equation and the kinetic equation of microorganism are introduced to describe the production of microorganisms, the formation of metabolites and the consumption and utilization of nutrients during MEOR. The model assumes that the permeability changes due to the retention of microorganisms at the pore surface and the clogging of the pore throats. In order to verify the applicability of the model, static experiments and core-displacement tests were carried out, and the experimental results were compared with the numerical simulation results. The results show that the model can indeed simulate the main biokinetic process of the experiment. Its promotion can be used for microbial enhanced oil recovery field test design, evaluation and effect prediction.
