Physical and mathematical modeling of the temperature distribution along the length of oil source rocks under microwave irradiation

The article presents the results of physical and mathematical modeling of the temperature distribution in an oil source rock sample under monodirectional microwave irradiation. The studies were performed at a radiation frequency of $2.45$ GHz. The mathematical model was validated based on the results of physical modeling of dielectric heating of the source rock to $115^{\circ}$C. Predictive calculations were carried out on the scale of a real object. The results demonstrate the volumetric nature of sample heating under microwave irradiation. The intensities of dielectric heating of the oil source rock at kerogen pyrolysis temperatures were determined, as well as the penetration depth of the electromagnetic field during kerogen pyrolysis.
