南海地区天然气水合物(可燃冰)开采及储运方案探讨

Investigation on Production,Storage and Transportation Plan of Natural Gas Hydrate in South China Sea

本文根据广东省天然气水合物开发先导试验区建设计划,提出“水下生产系统+深水半潜式生产平台+海底管道+陆地处理终端”的南海天然气水合物产业化生产储运方案,就该地区天然气水合物的特点、预处理工艺、配套生产设施等展开研究,并借签了南海深水气田开发的成功案例。研究成果对于南海地区天然气水合物开发生产及储运方案的选择,具有一定的参考价值。

This paper investigates the production,storage and transportation plan of natural gas hydrate,by aiming at the construction plan of natural gas hydrate development pilot area in Guangdong province.A scheme of“subsea production system+semi-submersible platform+subsea pipeline+terminal”is proposed for the industrial production,storage and transportation of natural gas hydrate in the South China Sea area.In this paper,the characteristics,pretreatment process and supporting production facilities of natural gas hydrate in this area are studied based on the successful development cases of deep-water gas fields in the South China Sea.
