چکیده
|
A novel copolymer containing nano-sio2 was synthesized by free radical polymerization using acrylamide (am),acrylic acid (aa),and nano-sio2 functional monomer (nsfm) as raw materials under mild conditions. the am/aa/nsfm copolymer was characterized by infrared (ir) spectroscopy,1h nmr spectroscopy,elemental analysis,and scanning electron microscope (sem). it was found that the am/aa/nsfm copolymer exhibited higher viscosity than the am/aa copolymer at 500 s-1 shear rate (18.6 mpa·s versus 8.7 mpa·s). it was also found that am/aa/nsfm could achieve up to 43.7% viscosity retention rate at 95°c. mobility control results indicated that am/aa/nsfm could establish much higher resistance factor (rf) and residual resistance factor (rrf) than am/aa under the same conditions (rf: 16.52 versus 12.17,rrf: 3.63 versus 2.59). at last,the enhanced oil recovery (eor) of am/aa/nsfm was up to 20.10% by core flooding experiments at 65°c. © 2013 zhongbin ye et al.
