| description | The invention discloses an offshore large-well-spacing horizontal well steam flood steam channeling early warning mechanism and steam channeling treatment method. The method comprises the steps that 1, an offshore large-well-spacing horizontal well steam flood steam channeling judgment standard is determined; 2, steam channeling prevention is conducted, specifically, an offshore large-well-spacing horizontal well steam flood steam channeling early warning mechanism is formed, and according to the steam flood steam channeling early warning mechanism, an offshore large-well-spacing horizontal well steam flood steam injection well section-selecting steam injection tubular column is matched, so that the matched steam injection well section-selecting steam injection tubular column can delay the steam channeling time; 3, steam channeling treatment is carried out: after steam channeling occurs, a plugging and adjusting process is adopted for conducting steam channeling treatment on a steam flood well set; and 4, on |
