EXPERIMENTAL STUDIES OF THE POSSIBILITY OF USING MODIFIED NATURAL WATERS TO INTENSIFY OIL PRODUCTION

Abstract

Currently, complex technologies are used to increase the ORC (oil recovery coefficient), the most promising of which are combinations of physico-chemical methods.

Modern methods of oil field development are accompanied, in addition to oil production, by the extraction of associated reservoir water, which, after appropriate purification and preparation, is used to maintain reservoir pressure. The purpose of the research in this article is to evaluate the possibility of using physico-chemical methods for modifying natural waters with further use to intensify oil production. In this regard, experimental studies have been conducted to study the effect of electrochemically modified natural waters on the oil recovery process.  The research was conducted on oil. As a result of experimental studies, it has been established that electrochemical modeling of mineralized natural waters makes it possible to obtain active aqueous solutions with the necessary alkaline or acidic properties without additional use of chemical reagents, thereby increasing the environmental safety of technologies and their economic efficiency.
