摘要
为了更好地对本源微生物驱油进行方案设计,很有必要发展本源微生物驱油数值模拟技术。采用室内实验方法,研究了本源微生物采油的机理,引入了微生物因子来描述微生物的特有作用,提出了三维三相本源微生物驱油数学模型,结合具体算例进行了数值求解,比较了不同注水时机对采油的影响。结果表明:该模型所模拟的结果和实际结果较相符,在所模拟的范围内,开始进行本源微生物驱越早越好。该成果对现场应有一定的参考价值和指导意义。
The paper presents a three-dimensional two-phase and multiple-component mathematic model of MEOR(microbial enhanced oil recovery) in dealing with the design of the field application. The model is based on the laboratory experiment and the microbial factor is introduced to describe the special mechanisms of microorganism. Simulation results are in agreement with the field results, and can provide the reference and guidance for the practical application.
