Abstract Aiming at the problem of a significant decline in production of super-heavy oil in the late stage of steam huff and puff, and a decline in the oil-steam ratio, this article proposes a series of comprehensive new technologies for 100-ton well cultivation, reservoir refinement, drive drain compound and reservoir potential tapping. Reservoir tracking adjustment have promoted balanced production of reservoirs, optimized reservoir steam injection, and advanced technology upgrades for super-heavy oil fields. The SAGD technology proposed in this paper breaks the current development bottleneck, fills the gap in the development of SAGD in medium and deep heavy oil reservoirs worldwide, solves the problem of super-heavy oil field development, and effectively improves the recovery of super-heavy oil.
