摘要

分析了深水气田开发过程中遇到的高产水问题及其带来的危害。针对高产水气田水合物生成问题,探讨了有效解决该问题的深水开发方法,包括水合物抑制剂的使用、海管保温技术、水下分离与增压技术等。通过分析每种对策的原理、技术进展及应用情况,总结了各自的技术特点、技术可用性、技术使用的主要影响因素及主要适用工况等。研究表明,含水量、海管长度和井流温度压力条件是影响方案选择的主要因素。

Abstract

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.
