  • Patent number: 11156069
    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.

  • Patent number: 11078768
    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.
