| 摘 要： | 针对气井关井压力恢复曲线异常（即关井后井底压力上升时井口压力下降）的现象，基于现场测试数据和文献调研，修正了井底压力计算模型。采用试凑法，从井流物组成在关井过程中有无发生变化两个方面对井口压力恢复曲线进行了校正。实例计算表明，该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，并对井流物组成相同或相近的气井具有一定的借鉴意义，为气藏试井解释和动态计算提供了基础和依据。

| Abstract: | Aiming at phenomenon of abnormal gas well shut down pressure build-up curve (i.e.,bottom hole pressure goes up while wellhead pressure goes down after the well is shut down),the bottom hole pressure calculation model is modified based on the practical test data and existing literature.By means of try and derror method,from two aspects if or not well stream composition changes while shutting down the well,the well head pressure build-up curve is corrected.Case study shows the method can eliminate the influence of gas well head pressure build-up curve abnormality on well test interpretation,and it provides a reference to the gas wells with same or similar well stream composition.The result plays a foundation for well test interpretation and dynamic calculation. |
