Synthesis and Rheological Properties of Polyacrylamide Nanospheres and SiO 2 /PAM Composite Nanospheres
View through CrossRef
Abstract
Polyacrylamide nanospheres are a kind of polymer material that can improve the development effect of oilfield water flooding and realize reservoir stimulation. However, due to its good water absorption, the strength cannot well meet the needs of practical production, and is forced to be limited to application on oil displacement. Therefore, in this paper, SiO
