The Method of Increasing Oil Recovery Through Thermal Impact
Abstract
This scientific paper thoroughly investigates the role and operational principles of thermal stimulation technologies in enhancing oil recovery from oil reservoirs. Based on the physical and chemical changes occurring during the application of heat to the reservoirs, it is observed that as the temperature increases, the viscosity of the oil decreases, and the interfacial tension between phases weakens. These changes facilitate the easier flow of oil, thereby contributing to increased production. Specifically, in the temperature range of 200-250°C, the viscosity of the oil can decrease several times, and the surface tension can reduce by 2-3 times, which enables easier extraction of oil.
The paper also presents various methods of thermal stimulation, including in-situ combustion, hot water injection, and steam injection technologies. The results of the study indicate that these methods can increase oil recovery by 10-40%. In addition to improving the efficiency of oil extraction, these technologies minimize environmental impacts. To understand how thermal stimulation works in oil reservoirs, the paper also explores the mathematical modeling of these processes. Differential equations and numerical solution methods are employed for predicting heat transfer. Methods for solving boundary inverse problems are applied to model the effects of thermal stimulation, allowing for more accurate assessments of heat processes in practical applications.
