摘要
利用锥板粘度计和旋滴界面表张力仪研究了丙烯酰胺 ( AM) - N-乙烯基 - 2 -吡咯烷酮 ( VP) - 2 -丙烯酰胺基 - 2 -甲基丙磺酸 ( AMPS) ( AM- VP- AMPS)共聚物水溶液与阴离子表面活性剂十二烷基苯磺酸钠 ( C18H2 9Na O3 S)及中性表面活性剂聚乙二醇辛基苯基醚 ( OP- 1 0 )的相互作用以及该复配体系与原油之间界面张力 .研究结果表明 :AM- VP- AMPS共聚物水溶液与表面活性剂复配会降低水相 /油相界面张力 ,阴离子表面活性剂 ( C18H2 9Na O3 S)会引起共聚物水溶液表观粘度的下降 ,而中性表面活性剂 ( OP- 1 0 )
Acrylamide(AM) N Vinglpyrrolidone(VP) acrylamido 2 methylprane sulfonic acid (AMPS) copolymer (AM VP AMPA) is a new polymer oil displacement agent, and it has a good salt resistance and a high viscosity conservation rate at high temperature. The recovery factor of polymer and surfactant compound oil displacement is usually higher than that of polymer oil displacement. The interaction of copolymer AM VP AMPS aqueous solution and surfactant C 18 H 29 NaO 3S (or OP 10), and the interfacial tension of the compound system and oil were studied by means of cone plate viscometer and spinning drop interfacial tensiometer. The results show that, with C 18 H 29 NaO 3S,the apparent viscosity of AM VP AMPS aqueous solution and the interfacial tension of the water phase/oil phase are all decreased. But the effect of OP 10 on the apparent viscosity is little.
