Optimization of Anti-freezing and Unblocking Measures for Natural Gas Wells and Pipelines: A Case from the Gaoqiao Area of Jingbian Gas Field, Ordos Basin

During winter production, new wells in the Gaoqiao area are concentrated in production, with high output, long single-well pipelines, high surface gathering and transportation pressure, and crisscrossing terrain.These conditions cause gas wells to be prone to freezing and blocking in winter, which significantly restricts gas well production.It is urgent to conduct research on anti-freezing and blocking measures at the wellhead.Starting from the current production situation in winter, this paper comprehensively sorts and categorizes key wells and those that are prone to freezing and blockage.The classification and frequency of freezing and blockage are statistically analyzed, and the reasons for freezing and blockage are studied.Solutions are analyzed for each situation, and overall, the impact of freezing and blockage on production is significantly reduced, fully ensuring the production capacity of gas wells in winter.
