We analyze the high water production problem of deepwater gas field and the harm of this problem. Aiming at the hydrate formation problem, the solutions which include hydrate inhibitor application, subsea pipeline insulation, subsea separation and boosting are described. By analyzing the principle, technical progress and application situation of each solution, we summarize the technical features, availability, main influencing factors and main application conditions of these solutions. The results show that the water content, the length of the pipeline and the temperature and pressure of flow are the main factors affecting the selection of the scheme.
