The application discloses a high-flux heat exchange device based on a thermo-chemical reaction auxiliary, which comprises a heat exchange chamber and a chemical phase change working medium. The chemical phase change working medium comprises a liquid cooling base fluid and a reversible thermal decomposition solute. The thermal decomposition temperature threshold of the reversible thermal decomposition solute is lower than the physical boiling point of the liquid cooling base fluid under the current environment. When the temperature or pressure of the heat exchange surface reaches the thermal decomposition temperature threshold, the reversible thermal decomposition solute undergoes an endothermic decomposition reaction on the heat exchange surface, rapidly generates a large number of non-condensable bubbles and high-frequency separates, thereby triggering strong local micro-convection disturbance of the fluid and absorbing a large amount of chemical decomposition heat, and finally achieving heat dissipation of the heating element. The application accelerates the transfer of wall heat by using a thermo-chemical reaction, and improves the separation rate of bubbles at the solid-liquid interface, breaks the engineering resistance that bubbles are difficult to nucleate and efficiently separate in traditional boiling heat transfer, and realizes rapid and large absorption and transfer of the combined chemical reaction heat of the solute and the latent heat of vaporization of the base fluid.

Method for extracting unconventional oil and complex for the implementation thereof

PCT designated stageWO2026142443A1ThermodynamicsThermochemical reaction
The invention relates to a method for extracting unconventional oil and to a complex for the implementation thereof. The method comprises injecting oxygen into an oil-bearing formation through injection-production wells, igniting the oil in the vicinity of an injection well, and displacing the oil toward production wells in an injection-production well cluster. Water is injected into the injection wells along with the oxygen, creating within the formation a pressure of the medium which is higher than that supercritical for water. A movable cloud of water in a supercritical state is formed at the well bottom. The combustion zone and the supercritical water cloud are induced to move through the oil-bearing formation from a depleted well to the next well. As the supercritical water cloud moves, it carries out thermochemical reactions, extracting hydrocarbons into itself and directing these hydrocarbons into the production wells to be brought to the surface. Oil recovery and the movement of the cloud are effectuated from the deepest wells. Having a cluster of injection-production wells that are hydrodynamically connected to one another makes it possible to sweep oil-bearing formations that extend over a large area, since the supercritical water cloud can be made to move from one injection-production well to another by changing the ratio of the flow rates of the water and the oil products in individual injection-production wells.
