建南气田天然气水合物的危害与防治

The Harm and Prevention of Natural Gas Hydrate in Jiannan Natural Gas Field

建南气田天然气开采、集输过程中,由于天然气水合物的生成,曾多次造成井筒、输气管线的堵塞,影响了建南气田的正常生产。从建南气田天然气水合物的形成及危害出发,探讨了水合物生成的原因,采用了提高节流后天然气的温度、加强气水分离、加注抑制剂等防治措施,取得了明显的成效。

In the course of natural gas exploitation and transportation in Jiannan natural gas field,the formulation of natural gas hydrate has caused the jam of well bore and pipeline,which has influenced the normal production of the gas field.Aim to this question,we have taken some prevention and cure measures and have made the obvious effect.
