The structures and properties of hydrophobic association polymers can be controlled using micelles. In this work, we synthesize a reactive surfactant monomer, KS-3, from oleic acid, N,N-dimethylpropylenediamine, allyl chloride. A strong synergistic effect between KS-3 cocamidopropyl betaine in aqueous solution enhances the hydrophilic dispersibility thereby transforming spherical micelles into cylindrical was grafted onto polyacrylamide chain via free-radical polymerization to obtain RES, polymer. Structural analysis revealed that RES assembled wormlike were more tightly arranged than those micelles, resulting compact network structure water, smooth surface, high thermal stability. Rheological tests synthesized with exhibited shear-thinning along different structural strengths viscoelasticities. Therefore, controlling micellar state effectively regulate polymer properties. obtained through micelle have potential applications fields demands, such as drug release, water purification, oilfield development.

During ultradeep oil and gas drilling, fluid loss reducers are highly important for water-based drilling fluids, while preparing high temperature- salt-resistance with excellent rheology filtration performance remains a challenge. Herein, micro-crosslinked amphoteric hydrophobic association copolymer (i.e., DADC) was synthesized using N,N-dimethyl acrylamide, diallyl dimethyl ammonium chloride, 2-acrylamido-2-methylpropane sulfonic acid, monomer, pentaerythritol triallyl ether crosslinker. Due to the synergistic effects of hydrogen bonds, electrostatic interaction, association, micro-crosslinking, DADC exhibited outstanding salt-resistance. The rheological experiments have shown that had shear dilution certain degree salt-responsive viscosity-increasing performance. could effectively adsorb on surface bentonite particles through interaction which bring more negative charge bentonite, thus improving hydration dispersion as well colloidal stability fluids. Moreover, fluids constructed based satisfactory properties (FLHTHP = 12 mL) after aging at temperatures (up 200 °C) salinity (saturated salt) environments. Therefore, this work provided new insights into designing fabricating high-performance treatment agents, demonstrating good potential applications in deep engineering.

To enhance oil and gas recovery, a novel hydrophobic terpolymer was synthesized via free radical polymerization. The consists of acrylamide, acrylic acid, monomers, is used as hydraulic fracturing fluid thickener for freshwater environments. Hydrophobic groups were introduced into to improve its tackiness temperature resistance. conformation key parameters monomers at different temperatures investigated through combination experiments molecular dynamics simulations. These methods employed elucidate the mechanism behind high-temperature experiment results show that, concentrations between 0.2% 0.4%, significant intermolecular aggregation occurs, leading substantial increase in solution viscosity. Configuring base synthetic polymer with 1% doping, apparent viscosities 129.23 mPa·s 133.11 mPa·s, respectively. viscosity rate 97%. crosslinked 1.5% organozirconium crosslinker form gel. controlled loss coefficient velocity filter cake C3 = 0.84 × 10-3 m/min1/2 vc 1.40 10-4 m/min 90 °C, meeting technical requirements water-based fluid. Molecular simulations revealed that radius gyration hydrophobically linked chain segments decreases increases. This due increased thermal motion segments, resulting less stretching intertwining chains. As result, chains move more freely, which solution. In conclusion, proposed system demonstrates excellent overall performance shows potential application recovery.
