核磁共振研究聚合物微球调驱微观渗流机理
Experimental study on microscopic percolation mechanism of polymer microsphere profile control and flooding by nuclear magnetic resonance
摘要
Abstract
The profile control and flooding experiments of polymer microsphere of different grain size are carried out using the artificial cores with different permeability,and the displacement results and displacement mechanisms are studied by NMR. Fluid distributions in the core pores of different size ranges after water flooding,polymer microsphere flooding and subsequent water flooding are analyzed by NMR spectroscopy,and the recovery rates of the core pores of different size ranges after water flooding,polymer microsphere flooding and subsequent water flooding are obtained. It is shown that the remaining oil in the pores of different size ranges can be driven out by polymer microsphere profile control and flooding,but the polymer microsphere of different size is suitable to the cores of different permeability. The microsphere of micrometer size is suitable to high permeability cores,and the microsphere of nanometer size is suitable to low permeability cores.关键词
