摘要:

基于目前国内外对微生物驱油的数值模拟研究资料和已取得的技术成果,发展了一个综合的微生物驱油三维三相多组分(水、油、气、微生物及其营养物、代谢产物等)数学模型。用全隐式方法对模型进行了差分,并讨论了由此得到的有限差分方程组的解法和模型所含参数的获取途径。通过一典型实例对微生物驱油的数学模型进行检验,对比了微生物驱与普通水驱后的含油饱和度分布和采出程度等。结果表明,应用该模型能够真实、详细地描述微生物体系在地层中的生长、运移和驱油过程以及分析解决受各种因素(微生物和营养物浓度、段塞结构、层间渗透率等)影响下的微生物驱油参数优化问题。

Abstract:

In this article, the actuality of internal and overseas study of Microbial Enhanced Oil Recovery numerical reservoir simulation was analyzed for the sake of further studying of the process of MEOR. At the same time, the author brought forward a series of effective threedimension and threephase mathematical simulation models and solved them by use of finite implicit difference method, and then discussed the approach to gain the parameters. These equations were tested by use of a typical geological model. At the same time, the microbial waterflooding were contrasted and normal waterflooding, then the influence factors (microbe and nutrition concentration, slug structure, interlayer permeability, etc.) and parameter optimization of MEOR were discussed.

Key words: microbial enhanced oil recovery, numerical simulation, parameters optimization, EOR
