Title: Method for thermo-chemical treatment of oil reservoir
Inventor: Vershinin Vladimir Evgenevich
IPC: C09K8/592
Filed: 2018-06-14
Granted: 2019-08-05
Abstract: FIELD: oil industry. 
     SUBSTANCE: invention relates to the oil-producing industry. Method of thermo-chemical treatment of oil formation involves pumping into oil reservoir required volume of binary mixture containing ammonium nitrate and sodium nitrite, and control during treatment of formation and temperature. Prior to injection of the binary mixture, reservoir capacity is determined, as well as primary measurements of temperature and pressure in the perforation interval of the well, depending on which volumes and modes of binary mixture supply are determined. One-pipe injection of preset volume of binary mixture is performed in two stages with consumption of binary mixture at the first stage of not more than 25 % of volume and pumping of separating water pack after the first stage. Binary mixture is prepared immediately before its pumping at well cluster site, through which oil formation is treated, by means of plants for preparation, mixing, averaging and supply of solutions, adding sodium nitrite to prepared solution of ammonium nitrate. During pumping of binary mixture at growth of pumping pressure more than 1.5 times from preset operating pressure consumption of binary mixture is reduced until pumping is stopped, after which water is supplied, and then, when pumping pressure is restored to working pressure, the remaining volume of the binary mixture is pumped. 
     EFFECT: technical result is stimulation and optimization of oil production process, increased efficiency of action on oil and gas bearing formation, increased safety at simultaneous reduction of costs.
