影响气井压力恢复资料解释的原因分析及解决方法

经对气井压力恢复历年测试资料的分析,总结出影响其形态的因素主要有井筒积液、井筒温度变化、压力计性能和工作制度改变等方面,针对各影响因素进行分析得出有效的解决方法,编制了考虑积液和温度变化的气井解释软件;对压力计的使用和现场施工提出了可行性建议,为气井测试施工与解释提供有利依据。

Reason Analysis for Influencing Data Interpretation of Buildup Pressure in Gas Well and Its Solutions

After analyzing test data of buildup pressure in gas well over the years,the factors affecting its shape mainly in terms of wellbore fluid,the wellbore temperature,pressure gauge performance and changes in work systems are summed up.Valid solution is drawn according to the various influencing factors having been analyzed,and interpretation software for gas wells considering the change of effusion and temperature is established.Feasible suggestions on the use of pressure gauge and on-site operation are put forward,which provides a favorable basis for the well test construction and interpretation of gas well.
