Abstract
Disclosed is a method for determining the dynamic adsorption retention of polymer capsules, belonging to the technical field of oil and gas field development engineering, which includes: (1) carrying out a thermal aging experiment to establish relational expressions between a capsule concentration and an aging time, as well as a polymer release concentration and the aging time; (2) setting up a polymer capsule displacement experimental device to determine the release concentration of polymers in effluent; (3) releasing polymers encapsulated by capsules in the effluent to acquire a total adsorption retention of polymers in a porous medium; and (4) inverting respective adsorption retentions of the capsule particles and the polymers in the porous medium.
