Study on Deep Water Flow Security Technology for Subsea Pipeline

Author of the article:Yan Ni, Wang Xiaodong, Hu Hongmei

Author's Workplace：College of Mechanical and Transportation Engineering, China University of Petroleum (Beijing)

Key Words：Deep water flow assurance; Multiphase flow technology; Natural gas hydrate; Subsea pipeline

Abstract：With gradual extension of offshore oil field development to deep water zone, more strict requirements are put forward for the mixed transportation pipeline design in the condition of high pressure and low temperature. Introduced are different kinds of subsea mixed transportation pipelines, proposed are some solving methods through pressure drop based on various kinds of complex flow patterns. Expounded are harms resulting from slug flow and put forward are some prediction and prevention methods. Virtual measurement becomes the main object of the development because precision of the multiphase flow metering is affected by the uniform of the multiphase flows. In the meanwhile, low temperature environment may lead to the formation of gas hydrate and subsea pipelines will be blocked accordingly and proposed are some solutions for such problems so as to ensure the safety of equipment and deep water pipelines.
