摘要
用乳状液稳定性实验考察了碱 -表面活性剂 -聚合物三元复合化学驱中油滴聚并规律。结果表明 ,乳状液中油滴上浮、絮集、聚并过程受水相组成变化的影响较大。原油中石油酸与碱的反应和碱的强弱、浓度有关。高浓度强碱体系油水混合后易形成 W/O型乳状液 ,低浓度弱碱体系油水混合后易形成 O/W型乳状液。
The emulsification and coalescence characteristics of crude oil/chemical flooding solution systems were investigated by observing the emulsion stability in terms of changes in specific concentrated phase volume The chemical flooding solutions studied were of NaCl,Na 2CO 3,NaOH,NaHCO 3,respectively The results indicated that the process of floating,flocculation and coalescence of oil drops were greatly influenced by components of chemical flooding solution The chemical reaction between petroleum acid in crude oil and alkaline solution was related to the strength and concentration of alkali When the strong base system with high concentration mixed with crude oil,W/O emulsion formed readily
