Description

technical field [0001] The invention belongs to the technical field of heavy oil thermal recovery, and in particular relates to an adaptively regulated supercritical hydrothermal combustion type multi-element thermal fluid generation system. Background technique [0002] Viscous oil, also known as heavy oil, refers to the viscosity greater than 50MPa s and the density greater than 0.92g / cm under the conditions of the oil layer 3 of crude oil. The global oil reserves are about 9-11 trillion barrels, 70% of which are heavy oils with high viscosity (heavy oil and super heavy oil account for 40%). At present, heavy oil recovery technologies such as steam huff and puff, steam flooding, and steam-assisted gravity drainage are mainly used in oil fields to exploit heavy oil. Steam as a heat carrier is injected into the formation to heat heavy oil, reduce the viscosity of heavy oil, improve its fluidity, and facilitate extraction. Nowadays, the increase of heavy oil production by c...
