CNOOC Research Institute, Beijing, 100027; 2.CNOOC Iraq Limited, Beijing, 100005 Abstract: Based on investigation of control methods of severe slug flow abroad, this paper reviews three methods used in China, including GLCC miniature separator method, automatic throttle method and gas lift method. Combining the GLCC with original slug flow trap has addressed the problem of slug flow in QK17-2 Oilfield, saving space and money at the same time. A set of on-line monitoring and automatic throttling system has been installated in Wenchang Oilfield which helps to keep stable and high production. In a West Africa deepwater oilfield jointly developed by CNOOC, a gas lift annulus and gas injection system have been installed to control the slug flow and increase production.
