Abstract
Aiming at the problem that the weak gel system has poor effect on the high temperature and high salinity reservoirs ,a kind of polymer nanosphere HP-2 system with temperature resistance and salt tolerance was developed .The particle size distribution and morphology of HP-2 were evaluated by laser particle size analyzer and optical microscope.The water absorption expansion curve of HP-2 was studied by using swelling ratio as the evaluation index .Finally the plugging ,anti erosion and profile control performance of polymer nanosphere HP-2 were evaluated using homogeneous cores and heterogeneous cores .The results showed that the polymer nanosphere HP-2 with an average particle size of 407 .2 nm were spherical particles with high sphericity .The water swelling ratio of HP-2 was 34 .1 g/g in the high temperature (90 ℃) and high salinity (97 686 mg／L ) reservoir .The results of three layers heterogeneous core flooding experiments show that the polymer nanosphere HP-2 system can enhance the oil recovery rate by 17 .3% on the basis of water flooding recovery .The polymer nanosphere HP-2 system has wide application prospects in high temperature and high salinity reservoirs .关键词
