气田气井管线常见堵塞原因及处理方法

Causes of Common Blockage of Gas Well Pipelines in Gas Fields and Treatment Methods

由于采气管线投产初期井下脏物较多、运行压力高等原因,管线冬季水合物堵塞频繁,影响了气井的正常生产。论文通过对高压采气管线造成堵塞的各种因素进行分析总结,探讨了高压采气管线堵塞的主要原因及防冻措施,提出了相应的意见和建议。

The gas hydrate blockage is frequent in winter due to the large amount of underground dirt and high operating pressure in the initial stage of the pipeline commissioning,which has affected the normal production of the gas well.The paper analyzes and summarizes various factors causing the blockage of the high-pressure gas production pipeline,probes into the main causes of the blockage of the high-pressure gas production pipeline and the anti-freezing measures,and puts forward the corresponding opinions and suggestions.
