摘要：
In recent years, deepwater areas have become important potential areas and growth poles for oil and gas resources. From tracking study, foreign cooperation to independent innovation, China National Offshore Oil Corporation (CNOOC) has made great progress in the deepwater field. Currently, it has deepwater blocks with corresponding rights and interests in West Africa, Brazil, and the Gulf of Mexico. Drilling and completion operations of more than 40 deepwater wells have been completed safely and efficiently. The development of the first self-operation deepwater gas field in China is being steadily advanced. CNOOC has mastered a series of deepwater well drilling and completion technologies, and has established a technical system involving deepwater risers, safe and efficient drilling in deepwater shallow layers, deepwater well testing and completion, deepwater well control and emergency rescue, and etc. Facing the future, CNOOC will focus on the fields such as high temperature and high pressure in deepwater zones, ultra-deepwater and deepwater wells, and deep-sea gas hydrates, further develop technologies for controlling operational risks and solving safe emergencies, strive to achieve informationization, intelligentialization and localization, and promote the further development of China's offshore oil industry. © 2019, Editorial Office of ACTA PETROLEI SINICA.
