Abstract
A mussel bionic gel composition includes: a mussel bionic copolymer and/or a mussel bionic compound, a cross-linking agent and water, wherein the mussel bionic copolymer includes a structural unit A from a vinyl monomer and a structural unit B from a vinyl-containing mussel bionic catechol group monomer; and the mussel bionic compound includes polyacrylamide and a mussel bionic catechol compound. The self-growth gel particle profile control and water plugging agent prepared from the composition is low in initial apparent viscosity, easy to inject and far in migration, has good shear repairing performance and is particularly applicable to a low-permeability fractured reservoir, thereby adjusting a micro-fracture network, improving a fracture channel and increasing waterflood efficiency and recovery efficiency.
