天然气水合物的结构特征及防治措施

Structural Characteristics of Natural Gas Hydrates and Prevention and Control Measures

概述了天然气水合物的生成条件和结构特征,介绍了加热法、添加防水合物生成抑制剂法、脱水法和降压法四种防治天然气水合物生成的措施,并对其防治机理进行了分析与研究。针对目前技术现状,认为利用计算机分子模拟技术对用量少且性能佳的各种抑制剂的研发,可以提高综合运用多种措施的防治效能,降低油气田生产和天然气输送的危害程度。

Generation condition and structural characteristics of natural gas hydrates are described.The authors introduce 4 methods(heating,hydrate inhibitor,dehydrated technique and pressure dropping methods)to prevent and control the generation of natural gas hydrates,and analyze and study prevention and control mechanism.The authors consider that developing an inhibitor of low volume and high performance by means of computer-based molecule simulation technology can obtain an optimal preventive effect based on comprehensive measures to eliminate the hazard during the production and transmission of natural gas.
