| 摘 要： | 针对吉林红岗油田实际开发需求,采用仅器检测和理论分析方法,开展了2种调剖剂即Cr3+聚合物凝胶和缓膨聚合物颗粒与二元复合体系的配伍性研究.结果表明,在二元复合体系中添加Cr3+交联剂后,体系黏度随Cr3+浓度增加而降低,界面张力及其随时间变化趋势受Cr3+影响不大,基本上都在10-2～10-3mN/m;而缓膨聚合物颗粒与二元复合体系接触后,体系黏度降低了50.60%～90.05%,界面张力由3.65×10-3mN/m最高上升到1.15×10-mN/m,并且添加量越多、时间越长,影响程度越大.由此可见,Cr3+聚合物凝胶与二元复合体系具有较好的配伍性,而缓膨聚合物颗粒则较差.流动性实验表明,在二元复合体系中加入Cr3+交联剂后,其阻力系数和残余阻力系数增加了几倍到几十倍甚至更高,流度控制能力得到明显改善.

| Abstract: | In view of the exploitation need of Jilin Honggang oilfield,the compatibility between profile control agent,such as Cr3+ polymer gel and polymer retarding swelling particles,and surfactant/polymer(SP) system was studied by means of theoretical analysis and instrument testing.The results showed that,when Cr3+ was put into the SP system,with the increase of the concentration of Cr3+,the viscosity of the system decreased,the variation tendency of the interfacial tension and interfacial tension were in good agr... |
