Preparation of Ultra‐Salt‐Tolerant OEMA Hydrophobic Modified Viscoelastic Profile Control Gel and Study of Its Salt Thickening Characteristics and Plugging Performance

To address the challenges of strong matrix heterogeneity, a limited flooding sweep range, and low oil displacement efficiency in high‐salinity and high‐water‐cut tight reservoirs, an amphiphilic monomer (OEMA) was introduced via aqueous dispersion polymerization to synthesize a profile control agent (SMAA‐n) with e...
