【摘要】 基于微生物驱采油机理,从数学模型和软件应用2个方面介绍和总结微生物驱数值模拟研究现状。由于经典微生物驱油模型(Islam模型、Zhang模型和Chang模型)不包含代谢产物组分,分别从产物主要以生物表面活性剂、生物聚合物以及其他产物模型来阐述现存模型的优缺点;主要从MTS,UTCHEM,CMG-STARS,ECLIPSE和MRST这5个方面总结微生物驱数值模拟的软件应用。当前微生物驱数学模型无法准确体现实际微生物驱油过程,均存在些许不足。因此,今后研究的重点和趋势为:1)建立完善的多孔介质空间模型来准确描述多孔介质内部孔隙结构;2)系统地研究微生物的形状尺寸对微生物运移和驱油的影响;3)建立多因素、多组分耦合影响下的微生物驱数学模型。更多还原

【Abstract】 Based on the mechanism of microbial enhanced oil recovery(MEOR), the advances in numerical simulation of MEOR were presented with particular reference to mathematical models and its application. Since the classical MEOR model(Islam model, Zhang model and Chang model) does not contain the component of metabolite, the advantages and disadvantages of existing models were mainly described by biosurfactants, biopolymers and other models, respectively.The software applications of numerical simulation were mainly described from five aspects: MTS, UTCHEM, CMGSTARS, ECLIPSE and MRST. The current mathematical model of MEOR cannot accurately reflect the actual MEOR process. Therefore, the focus and trend of future researches are follows: 1) establishing a perfect spatial model of porous media to accurately describe the pore structure inside porous media; 2) systematically studying the shape and size of microorganisms for microbial transport and oil displacement. 3) developing a mathematical model for MEOR under the coupling effects of multi factors and multi components.更多还原
