长庆气田天然气水合物防治浅议

Prevention of Natural Gas Hydrate in Changqing Gas Field

根据长庆气田地面建设特点,详细介绍了长庆气田防治天然气水合物生成的方法及甲醇回收再生的配套工艺技术。指出采用膜分离脱水、动力学抑制剂和复合抑制剂法是防治天然气水合物的发展方向。

According to characteristics of Changqing Gas Field ground surface construction,described are methods used to prevent natural gas hydrate from forming and relative processes and techniques for methanol recovery and regeneration in Changqing Gas Field. Methods such as dehydration by membrane separation,dynamic depressant and composite depressant are used to prevent natural gas hydrate from forming,which can reduce costs.
