| 摘 要： | 天然气水合物样品保压取样技术已经成熟，但保压样品只能进行压降处理成为常压样品，这种方法很大程度上影响了水合物在沉积物中的存在初始状况，压力的急骤变化以及温度的变化都会引起沉积物中水合物成分析出，影响后处理的判别。样品保压转移及处理技术不仅是未来天然气水合物资源勘探技术的发展趋势，也是重要技术手段之一。天然气水合物保压样品的获取、检测、处理是天然气水合物取样技术从初级走向成熟阶段的重要标志。介绍了天然气水合物沉积物样品保压转移及处理技术的设计思路及系统各组成单元。该系统主要由天然气水合物样品保压转移系统、天然气水合物保压样品在线探测及岩心分析系统等2部分组成。该系统的设计为今后天然气水合物资源的勘探和开发提供了很好的技术支撑。

| Abstract: | Pressure keeping technique in gas hydrate sampling is matured, but the technique for post- treatment of samples under pressure remains unsolved. The post treatment will affect the initial pres- ence of hydrates in sediments. Abrupt changes in pressure and temperature will cause the release of hydrate from the sediment and influence the results of later treatment. The technique for transporta- tion of pressured samples and post treatment, which includes the acquisition, testing, and treatment of gas hydrate samples, is not only the requirement of gas hydrate resources exploration, but also the mark of the maturity of the gas hydrate resource exploration technology. In this article, we made a design of the technology system for transportation and post treatment of gas hydrate samples under its original status. It includes the pressure-keeping transportation system and an online detection and a- nalysis system. |
