- Аннотация: . Transition to the development of hard-to-recover hydrocarbons, including in regionsthe far north, is fraught with difficulties in using classical technologies development. This isdue to the low porosity and permeability of the reservoirs, high viscosity of the formation fluidand the manifestation of abnormal (non-Newton) properties of hydrocarbon fluids. In thisregard, for more than ten years, pilot field research (FPI) in terms of the selection andoptimization of technologies for collectors of complex structures. Since 2011, at thedepartments of the underground hydromechanics of Gubkin Russian State University of Oiland Gas (NRU) and gas wave dynamics of the Lomonosov Moscow State University, researchis underway on the use of thermogas-chemical method with an injection of a binary mixture tostimulate the inflow. Since 2011, several settlement codes of different levels were created,which allowed carrying out support (pilot) in various fields. Based software products managedto evaluate the characteristics in the chemical reaction zone decomposition of the workingchemical composition, evaluate safe regimes, excluding damage to the wellbore and assess theprolongation of the effect. Published more than 20 works (including patents) with theparticipation of the authors. Since 2019 the mathematical model is significantly complicated:the multiphase and non-isothermality of the process, non-uniformity of the flow. Currentlyestablished generalizing code, in the mathematical model of which is additionally taken intoaccount different compressibility of phases and rheological properties of fluids, which allowsmore fine-tune the computational code for the type of a specific field, taking into account itsgeological features and damage to the bottomhole zone in the previous stages of development.
