伏龙泉气田天然气冬季集输冻堵及预防措施分析

Freezing and Blocking of Natural Gas in Fu Longquan Gas Field and Analysis of Preventive Measures in Winter

分析天然气冬季集输过程中产生冻堵的原因,提出预防冻堵的措施,通过入冬前对管线进行吹扫,排出管线积液,冬季集输气过程中进行生产动态分析制定合理的"一井一策"排液制度和加甲醇制度,起到良好的预防冻堵作用,确保冬季气井正常生产和安全平稳供气。

Analysis of natural gas in winter freezing causes transmission process, puts forward the prevention measures of freezing, purge the line before winter, drain effusion, Production dynamic analysis in the process of gas gathering and gas transmission in the process of making a reasonable ＂one well and one policy＂ drainage system and methanol system, lead to good prevention of freezing and plugging, ensure normal production and safe and stable gas supply in winter gas well.
