[0058] In order to have a clearer understanding of the technical features, objectives and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.
[0059] The present invention provides a method for switching to fire flooding in the late stage of steam-assisted gravity drainage of heavy oil reservoirs. In the expansion stage of the steam cavity of the steam-assisted gravity drainage, when the steam cavities of adjacent pairs of injection and production wells merge, the middle The injection well of the injection-production well pair is ignited by injecting air, the production well of the well pair and the production wells of the left and right adjacent well pairs produce production, and the injection wells of the left and right adjacent well pairs are converted into fire-flooded exhaust wells; The exploitation method can use high-temperature fire flooding front to effectively sweep the remain...
