摘　　要：采用插值计算法和图解法进行气井井筒压力测试数据解释,需要录取标准的井筒压力分布数据。对于录取到的非标准异常数据,直接采取插值计算法和图解法,往往会造成分析解释的错误和气井生产工况诊断的失误。从井下压力计停点设计、井筒流体物性和相态特征等方面入手,对异常井筒压力测试数据产生的原因进行了分析,并利用相关数据和常识,对异常数据的解释和分析处理提出了具体的方法和思路,提高了资料录取、解释及应用的准确性。Data of borehole pressure testing can be interpreted by using the interpolation calculation and diagram methods after the standard data of borehole pressure distribution is obtained. The direct usages of interpolation calculation and diagram method can result in a misinterpretation and judging error of production performance in gas well for the acquired non-standard abnormal data. This paper analyzes the generating reasons of abnormal borehole pressure from the design of pressure gauge termination, borehole fluid physical property and phase state features. It also provides some explaining methods and thoughts of abnormal data processing through the use of related data, which improves the accuracy of data acquirement and interpretation.
