Abstract

 Hydrophilic-hydrophobic polymers have the potential to profoundly change the ability to enhance oil recovery in injection technology and are chosen for application as a new enhanced oil recovery method. The article mentions the results of research investigating the influence of factors on the viscosity of hydrophilic-hydrophobic polymers based on polyacrylamide (hydrophobically associating polyacrylamide-HAP) used in injection technology to enhance recovery. Oil: HAP 6S, HAP 3SP and HAP 2SP. An increase in polymer viscosity can improve the scavenging efficiency during enhanced oil recovery, the bulk viscosity of polymers is based on molecular chain extension and physical obstruction of solvated chains, viscosity solutions of synthetic polymers, studied as functions of concentration, temperature, and salinity. The research, survey, and evaluation will select the appropriate hydrophilic-hydrophobic polymer content to withstand salinity (NaCl content is about 3 - 3.5%) for immediate application on offshore drilling rigs. Heat resistant when working in high-temperature environments up to 110 oC. The results of this research are the premise for the next evaluation in the process of proposing the application of hydrophilic-hydrophobic polymers for the polymer injection process to enhance oil recovery in our country's production wells, especially in the Miocene strata.
