【摘要】 根据天然气水合物生成的热力学和动力学规律。讨论了了三类天然气水合物阻止剂的作用机理。热力学阻止剂可用于高寒地区,但用量偏大。动力学阻止剂和防聚剂用量小,但前者不能用于高寒地区,后者能用于气井。三类天然气水合物阻止剂具有各自适合的场合和发展空间。更多还原

【Abstract】 Based on the chemical thermodynamics and kinetics law of natural gas hydrate formation,The mechanisms involved in three classes of gas hydrate inhibitors are discussed.The thermodynamical inhibitors can be used to high frigid zone,but are often very expensive,The kinetic inhibitors and anti-agglomerants have low dosage,but the former is not applicable in high frigid zone,and the latter is not applicable in the gas well.Three classes of gas hydrate inhibitors have their own suitable occasions and development space.更多还原
