【摘要】：以丙烯酰胺(AM)、丙烯酸(AA)、N-烯丙基油酰胺(NAE)和3-烯丙胺基羰基-1-乙基吡啶溴化铵([mAEPy]Br)为单体,采用氧化还原引发体系,制备了一种含吡啶离子液体结构疏水缔合聚合物驱油剂AM/AA/NAE/[m-AEPy]Br。对共聚物进行了红外、核磁表征,并测定了其增黏性、剪切稀释性、耐温抗盐性,对其提高采收率能力进行了评价。结果表明:2 000 mg/L的共聚物溶液表观黏度可达510.3 m Pa·s;在剪切速率为510 s-1下,其表观黏度为27.2 m Pa·s,且在90℃时其表观黏度为42.8 m Pa·s;在10 000 mg/L NaCl、1 500 mg/L MgCl_2和1 500 mg/L CaCl_2溶液中,其表观黏度分别为21.8、27.4和27.0 m Pa·s;在模拟驱油实验中,共聚物溶液的采收率提高了11.4%。
[Abstract]:Using acrylamide (AM), acrylic acid (AA), N-allyl oleamide (NAE) and 3-allylamino carbonyl-1-ethylpyridyl ammonium bromide ([mAEPy] Br) as monomers, the redox initiator system was used. A hydrophobically associating polymer flooding agent AM/AA/NAE/ [m-AEPy] Br. with pyridine ionic liquid structure was prepared. The copolymers were characterized by IR, NMR, and their viscosity, shear dilution, temperature and salt resistance were measured, and their ability to improve oil recovery was evaluated. The results show that the apparent viscosity of 2 000 mg/L copolymer solution can reach 510.3 m Pa s; at the shear rate of 510s ~ (-1), the apparent viscosity is 27.2 m Pa s, and the apparent viscosity is 42.8 m Pa s; at 90 鈩，
