摘　　要：近年来我国对环境的要求愈来愈严格,进入十四五时期,国家更是提出了“碳达峰、碳中和”的环境目标,加之我国经济总体量不断快速增加,对能源的需求也急剧上升。为同时满足经济的发展与环保的高要求,清洁能源的使用需求势必快速增加。天然气作为清洁能源之一,其需求也会随之快速增加。生产压差是气井开采过程中的关键环节之一,生产压差过小,经济效益差,生产压差过大,气井产量递减快,采收率低。因此,如何确定气井合理生产压差就显得尤为重要。对气井合理生产压差的确定进行了研究分析,对提高气井采收率、保障气井高效开发具有重要意义。In recent years,my country’s environmental requirements have become more and more stringent.In the 14th Five-Year Plan period,China has even put forward the environmental goals of"carbon peak and carbon neutrality".In addition,the overall volume of my country’s economy continues to increase rapidly.The demand for energy has also risen sharply.In order to meet the high requirements of economic development and environmental protection at the same time,the demand for clean energy is bound to increase rapidly.Natural gas is one of the clean energy sources,and its demand will also increase rapidly.How to ensure the efficient extraction of natural gas is particularly important.The production pressure difference is one of the key links in the production process of a gas well.If the production pressure difference is too small,the economic benefits are poor,the production pressure difference is too large,the gas well production declines quickly,and the recovery rate is low.Therefore,how to determine the reasonable production pressure difference of a gas well is particularly important.In this paper,the determination of the reasonable production pressure difference of gas wells was researched and analyzed,which is of great significance for improving the recovery rate of gas wells and ensuring the efficient development of gas wells.
