It is important to increase the efficiency of hydrocarbon production from productive reservoirs of oil and gas fields around the world. The main method of oil production is waterflooding, which ensures a fairly high level of oil production from deposits. In this regard, an analysis of the practical application of the flood method and theoretical studies in the USA, Great Britain, Saudi Arabia, the Russian Federation and other developed countries shows that the effectiveness of this method depends on the correct choice of object. technology of its application. In this direction, hydrodynamic models of multiphase multicomponent fluids and methods for their implementation are important for the correct selection of objects and technologies, as well as for the development and optimization of the theoretical basis of geological and technical activities.
The purpose of the research is to develop improved hydrodynamic models of filtration of an oil-gas-condensate mixture in a porous medium, taking into account the phase transition of the condensate, the effect of acid on the calcite and dolomite reservoir of the oil reservoir, taking into account the chemical reaction, as well as taking into account the chemical reaction of the carbonate reservoir, processing the oil reservoir, taking into account stone clogging .
The scientific novelty of the study is as follows:
Based on the theory of liquid and gas movement, a mathematical model of the process of filtration of an oil-gas-condensate mixture and an algorithm for calculating the solution of the corresponding problem based on the “large particles” method have been improved;
Using a physicochemical approach, a mathematical model of the effect of acid on the oil reservoir’s calcium collector and a computational algorithm for solving the problem based on the “large particles” method have been developed;
A mathematical model of the effect of acid on a dolomite reservoir of an oil reservoir and a computational algorithm for solving the problem based on the “large particles” method have been created;
A mathematical model of the effect of acid on a carbonate reservoir of an oil reservoir has been created, taking into account the clogging of rocks, and a computational algorithm for solving the problem based on the “large particles” method;
Based on the created numerical models, calculation methods with a graphical interface and application software packages have been developed that allow multidimensional calculations using medium-power personal computers.
