Abstract: The invention relates to the recovery of heavy oil reservoirs, and more particularly to a supported catalyst-assisted microwave method for exploiting a heavy oil reservoir. The method includes: (1) injecting a slug of a supported catalyst fluid into the heavy oil reservoir; (2) placing a microwave generator in the heavy oil reservoir to perform volumetric heating on an oil layer containing the supported catalyst fluid; and (3) turning off the microwave generator and injecting water into the heavy oil reservoir for subsequent displacement, where a water injection rate is 3 m/d or less.

Abstract: Disclosed belongs to the technical field of oil and gas field development engineering, and particularly relates to a super heavy oil development method for strengthening an SAGD steam chamber to break through a low physical property reservoir. The super heavy oil development method for strengthening the SAGD steam chamber to break through the low physical property reservoir includes the following steps: (1) selection of a developed oil reservoir; (2) well distribution; (3) steam chamber forming; (4) steam chamber expansion; (5) steam chamber strengthening. The method may enhance the ability of the steam chamber to break through the low physical property reservoir, enlarge the development height of the steam chamber, and further improve the SAGD development effect of super heavy oil.

Abstract: A novel inorganic fine particle reinforced foam system for an oil-gas field and preparation method thereof. The reinforced foam system comprises a gas phase and a liquid phase; the gas phase is nitrogen, carbon dioxide or the air; the liquid phase is prepared from, by mass: 0.2-0.8 wt % of a foaming agent, 0.5-2.0 wt % of novel inorganic fine particles and balance of water; the novel inorganic fine particles are fine particulate matter with diameters being smaller than or equal to 2.5 microns captured and screened from the atmosphere.
