摘要： 概述了表面活性剂对天然气水合物的作用, 一方面可用表面活性剂来提高水合物的生成速率, 因天然气水合物的巨大储气特性和方便、安全的存储方式使其具有极大的工业应用前景; 另一方面, 可用表面活性剂来抑制水合物的生成, 在天然气的整个流动过程中, 一旦形成水合物, 就会造成设备及管道堵塞, 影响正常的生产和运输, 甚至造成停产等事故。所以, 加入少量的表面活性剂来避免水合物的生成显得尤为重要。

Abstract: Surfactant can be used not only to increase generated velocity of natural gas hydrate, but also to inhibit from its generation. The former effect will bring itself to broad prospect for commercial application due to its huge gas capacity and safe and convenient storage feature. The latter one could result in plugging of equipment and pipe, affecting normal production and transportation and even more cause off production, owing to forming the hydrate in the gas flowing process. Hence, adding some surfactant can effectively avoid such a generation of natural gas hydrate.

Key words: natural gas, hydrate, surfactant, effect
