Protruding part has first side surface located on a side of protruding part that is located away from pivot part. An axis of pivot part is spaced apart from first side surface by first distance along first direction. Pivot part is spaced apart from first side surface by second distance along second direction. First direction is different from the second direction, and first distance is different from second distance.

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.
