摘要
长期以来，人们无法正确解释具有异常的气井关井压力恢复曲线（即关井井底压力上升时井口压力下降），这种异常与井筒相分离引起的完全不同。本文以井筒传热分析为基础，考虑气井关井后井筒流体相态及温度降落，提出异常气井井口压力恢复曲线的处理方法。实例计算表明，本文提出的理论和方法可以消除气井井口压力恢复曲线异常对试井解释的影响，从而获得正确的试井解释结果。
or a long time past,the adnormality of pressure build up curve of gas well can not be correctively interpreted.Based on wellbore heat transfer analysis,by considering wellbore fluid phase state and temperature drop after closing well,the treatment method of adnormal pressure build up curve of gas well wellhead is proposed out.The practice computation shows that the influence of the adnormality of wellhead pressure build up curve on well test analysis can be eliminated by the method to get corrective well test analysis result.
