摘要
介绍了天然气水合物的结构和危害,总结了预测天然气水合物生成条件的主要方法,包括经验图解法、相平衡计算法、统计热力学计算法等,阐述了防止水合物形成和排除已生成水合物的常用技术,包括脱水、脱轻烃、降压、提高流动温度、加化学添加剂等。
An introduction of the construction and the harm of gas hydrate, the summary of the main methods forecasting gas hydrate formation conditions, which include empirical graphic method, phase equilibrium compute method and statistics thermodynamics method, is included in the paper. The paper also illuminates the common technology preventing and removing the?hydrate, such as dehydration, light hydrocarbon deprivation, decompression, raising the temperature of flow and adding chemical additives, etc.
