摘要
本文针对我国表面活性剂/聚合物驱油的实际,研究了石油磺酸盐(PS)、正丁醇(R_4OH)和矿化水对水解聚丙烯酰胺(HPAM)溶液流变性的影响。结果表明,PS对HPAM溶液流变性的影响与介质的矿化度有关:非矿化水介质中,PS对HPAM溶液性质的影响类似于无机盐,能降低HPAM溶液的表现粘度(η_α)和稠度系数(k);当系统中含有一定浓度矿化水时,PS却能升高系统的η_α和k值,降低流型指数(n),使系统的非牛顿性增强。在含有PS和矿化水的HPAM系统中加入R_4OH,系统的η_α和k值会有所增加。
Based on the real condition of surfactant-polymer flood, this paper deals with influence factors of rheological properties of hydrolyzed polyacrylamid ( HPAM ) solution, such as petroleum sulfonate ( PS ) , n-butyl alcohol ( R4OH ) and mineralized water. The result shows that the influence of PS on rheological properties of HPAM bears a relationship to salinity of medium. In nonmineralized water medium, the influence of PS on property of HPAM solution is like inorganic salts which could decrease apparent viscosity (ηa) and thickness coefficient (K) of HPAM solution. When the system contains a certain concentration mineralized water, PS could increases ηa and K values of the system and decreases flow pattern index (n), increasing the Newtonian behavivr of the system. When R4OH is added into the HPAM system containing PS and mineralized water ηa and K values of the system is increaesd.
