The effect of a polyacrylamide-based composite polymer on oil displacement

ducts. The produced oil is highly paraffinic, highly emulsified and low-sulfur. In this regard, to increase oil recovery from oil and gas fields, it is necessary to select available raw materials, as well as new technologies based on the use of effective modified polymer reagents. А technology has been developed for the production of new composite surfactant polymers of the MPAA series based on polyacrylamide by hydrolysis with sodium hydroxide followed by modification in the presence of formaldehyde and fatty acids of gossypol resin, at a temperature of 353-363 K, time 4.0-4.5 hours, the ratio of reagents is 1:0.8, resistant to aggressive environments and high temperatures. As a result of the modification, the ability to regulate the surface-active properties of composite polymers in the presence of fatty acids of gossypol resin has been achieved. The surface tension of the modified PAA was σ=43.6 N/m. Mathematical optimization of the main parameters of the process of obtaining composite surfactant polymers based on hydrolyzed and modified PAA. Mathematical optimization of the main parameters of the process of obtaining composite surfactant polymers based on hydrolyzed and modified polyacrylamide was carried out.
