【摘要】 基于室内实验和矿场试验结果,对在稠油油藏热水驱中加入低质量分数表面活性剂时的驱替机理及所涉及的物理化学现象进行了研究,建立了三维三相的热活性水驱数学模型,并运用自行开发的软件对辽河油田一实际区块进行了模拟计算,对稠油油藏热活性水驱的渗流机理及加入表面活性剂时影响热活性水驱驱油效果的因素(加入表面活性剂的用量、时机、方式)进行了分析研究,得出了一些有益的认识。更多还原

【Abstract】 Based on the results experiment study and field tests,this paper concerns mainly about the mechanism of fluid flow and physicochemical phenomena is hot water flooding process with surfactant,and presents a three-dimen-sion,three-phase mathematical model of hot water flooding with surfactant.In an actual oil field,the developed software is used to study the mechanism of fluid flow of hot water flooding.Various factors which affect the flooding effects(such as the quantity,concentration,timing,pattern of surfactant injection)are investigated and some helpful conclusions are given.更多还原
