the invention relates to the technical field of oil exploitation, and particularly relates to a resin polyacrylamide gel profile control agent.

Background art:

with the continuous development of tertiary recovery and the gradual extension of the oil well exploitation limit, the increase of water yield is a main problem which prevents the oil from being continuously exploited. The most common method at present is to use a profile control agent to maximize the service life and the production life of the oil well.

The original profile control agent is only simple cement paste, then oil-based cement, lime cream, active thick oil and the like are successively developed, and in the seventy years of the last century, water-soluble polymers, gels and the like are applied to oil fields and achieve certain effects. At present, the plugging agent is mainly applied widely by technologies such as colloidal dispersion gel, expanded particles and flexible particles, but has certain defects, such as long pretreatment time, uncontrollable sol time and poor profile improvement effect.
