稠油表面活性剂乳化降黏效果及其作用机理研究——以渤海BZ25-1s油藏为例
Emulsification Process and Mechanism of Surfactants Used in Heavy Oil: Taking BZ25-1s Reservoir in Bohai Area as an Example
摘要
Abstract
Aiming at the reservoir geological characteristics and fluid properties of BZ25-1s oilfield in Bohai reservoir,taking diversion ratio,interfacial tension,viscosity and structure of the emulsion as evaluation index,the reducing viscosity effects of emulsification and its related mechanism were studied.The results showed that,when the ratio of oil and water was less than 7∶3,and the concentration of emulsion agent was higher than 600 mg/L,the intensified disperse system could form emulsion liquid with crude oil,and its ratio of reducing viscosity could reach 80%.Compared with the intensified cold production system,the intensified dispersion system had a significant advantage in demulsification,reducing interfacial tension and anti adsorption.The emulsification of this system and crude oil could lead to part of the component getting into the crude oil,which influenced the interfacial tension and emulsification effects between crude oil and the intensified disperse system.The intensified dispersion system can reduce the injection pressure and water content increasing rate,and it can enhance the oil recovery more effectively.关键词
