高浓度三元复合体系性能评价及机理分析
Performance evaluation and mechanism analysis of ASP system with high concentration
摘要
Abstract
Aiming at actual demand of oilfields ,the viscosity ,interfacial tension ,static ad-sorption property , rheological behavior and flow characteristics of alkali/surfactant/polymer (ASP) system have been evaluated through instrument test and theoretical method .The results showed that with the increase of alkali concentration ,viscosity and interfacial tension of ASP sys-tem decreased .With the increase of surfactant concentration ,viscosity and interfacial tension of ASP system decreased .With the increase of surfactant concentration ,viscosity of ASP system first decreased then increased ,and interfacial tension decreased .In the ASP system ,static ab-sorption of surfactant was the largest ,then alkali followed and polymer came last .With the in-crease of alkali concentration ,viscoelasticity of ASP system decreased .Surfactant had little im-pact on the viscoelasticity of Asp system .As is showed in flow characteristics experiments ,re-sistance coefficient and residual resistance coefficient of ASP system decreased after descaling of solvent water .With the decrease of alkali concentration ,polymer concentration increased and core permeability decreased ,resistance coefficient and residual resistance coefficient of ASP sys-tem increased .With the increase of surfactant concentration ,resistance coefficient and residual resistance coefficient of ASP system first decreased then increased .关键词
