Evaluation of downhole reactor parameters for high viscosity oil production

The problem of high-viscosity oil production is becoming more urgent due to the depletion of traditional hydrocarbon reserves. This work evaluates the influence of various parameters of the downhole reactor, which plays an important role in the technology of extraction of high-viscosity oil. Special attention is paid to the length of the cylindrical heater, the heat flux density, the filtration rate and the radius of the heater. As a result, a formula was obtained for calculating the optimal length of the heater, depending on certain reactor parameters. Purpose . To investigate and determine key parameters such as the length of the cylindrical heater, the filtration rate, and the radius of the cylindrical heater. To obtain a formula that will accurately calculate the optimal length of a cylindrical heater. Methods . The study of theoretical aspects based on the physical laws that describe the processes of heat transfer, as well as on the thermophysical properties of high-viscosity oil. Comparison of various parameters of a cylindrical heater to determine the optimal length. results. In the course of the research, the relationships between the value x, m were established for the possibility of creating a reactor with the best characteristics at different values of heat flux density, filtration rate, radius of the cylindrical heater. Conclusion . Studies have shown that the length of a cylindrical heater in a reactor depends on the radius of the heater, the linear density of the heat flow and the filtration rate. At heat flux densities of 1000 J/(m 2 ·s), 1250 J/(m 2 ·s), 1500 J/(m 2 ·s), the length of the cylindrical heater at various values of heat flux density loss takes values in the range from 0.94 m to 2 m; at constant heat flux density losses – from 0.66 m to 3.3 m; It was found that as the heat flow increases, the length of the cylindrical heater decreases by 2 times, and as the filtration rate increases, it increases by 1.2 times. At different values of the radius of the cylindrical heater, its length remains unchanged, since the difference in length is insignificant.
