Gravitational sorption method for extraction of vanadium-containing oil from reservoirs with the use of redox polymers

Abstract

The article considers the possibility of extraction of residual oil reserves, based on the use of previously drilled wells and creation of conditions for drainage of formation fluid into production wells due to gravity forces and sorption processes of vanadium interaction in oil with injected redox polymers. The article makes a significant contribution to world science when studying the processes of extracting residual oil reserves from reservoirs and metals from liquid media, including oil. As a result of the analysis of the proposed method of extraction, the authors for the first time prove that the technology under consideration allows increasing the oil recovery factor and expand the scope of redox polymers when extracting oil from seams and associated metals. The proposed redox polymers have improved physico-chemical, oxidation-reduction and sorption-kinetic properties. Their application will allow solving the actual problem of import substitution of expensive foreign products for oil production. This makes it possible to implement integrated development of such oil fields as Buzachi and others with the extraction of associated metals and to improve the quality of oil and oil products.
