Abstract
A temperature-resistant and salt-tolerant in-situ plugging-enhanced gel composition, a gel, and their preparation method and application are provided. The gel composition includes a first monomer, a second monomer, a first crosslinking agent, a second crosslinking agent, an initiator, an enhancer, and water; optionally, the composition further includes a third monomer. The gel can undergo re-crosslinking under stimulation by high temperature and CO-acidic conditions to form the bulk gel, thereby avoiding issues associated with in-situ gel systems such as crosslinking uncertainty, chromatographic separation, and susceptibility to reservoir damage, while simultaneously achieving enhanced plugging capability under in-situ reservoir conditions.
