Abstract: As offshore oilfields gradually enter the middle and late stages of development, it is more difficult to adjust injection and production. How to effectively use such difficult and marginal reserves has become an urgent technical problem. At present, the overseas intelligent well technology has been successfully applied for more than 20 years, while China's intelligent well displacement technology has just stepped into the best stage of leapforg development stage. Aiming at the needs of increasing production in offshore oilfield and the status of upgrading intelligent well, this paper reviews the theory and application of intelligent well technology at home and abroad. According to the development features and difficulties of continental sedimentary oilfield, the authors analyze the restriction in the leapfrog development of intelligent well technology in China offshore, and discuss the target direction and potential paths of the upgrading intelligent well technology. The studies have shown that it is of great potential for joint upgrading of intelligent well technology and digital oilfields. The breakthrough of technology has laid a solid foundation for systematic upgrade. The low-cost application of intelligent well technology has the great significance to increase the storage and production in offshore oilfield.

Key words: offshore oilfield, new digital infrastructure, intelligent well, upgrade equipment, digital oilfield
