摘要
在分析微生物采油机理及微生物作用前后渗流阻力变化的基础上 ,建立了微生物吞吐和微生物驱油的产油量、产液量、增油量和含水率变化的数学模型。该模型简单应用微生物与原油作用前后粘度及相对渗透率的变化数据和微生物处理前区块 (油井 )的生产数据 ,即可预测出利用微生物采油时的采油量、增油量和含水率。应用实例表明 ,所建模型的预测结果与实际结果有很高的一致性。
College of Petroleum Engineering in the University of Petroleum, China, Dongying 257061The mechanism of microbial enhanced oil recovery and the change of oil and water permeability resistance in situ biological process for oil production are analyzed. The predicting models of oil production, produced fluid, well stimulation and water cut change are set up. According to the data of viscosity and relative permeability of oil before and after microbial treatment and the production data of treated wells, the oil production, the amount of increasing oil and the change of oil and water cut can be easily predicted by this model. The application examples show that the prediction result of the model is in good agreement with the data of oilfield.
