| 摘 要： | 井筒效应包括井筒存储效应、井筒相再分布、变井储以及质量、动量变化。以往的试井分析方法没有考虑井筒质量、动量变化对压力动态的影响，然而，测试过程中流体由井底至井口的温度会发生变化，流动速度也可能增加或减小．不考虑这些因素对试井分析结果会产生较大的影响。利用Fair W B考虑动量效应的数学模型，用Laplace变换求解．形成了新的理论图版，用该图版研究分析了各因素对油井压力动态的影响。图2参5

| Abstract: | Many factors, including well bore storage, reservoir and fluid properties, flow behaviour, etc., could affect the pressure transient analysis of oil wells. Previous well testing analysis ignored the effects of mass and momentum changes in the pressure transient response. However, the temperature changes from the bottom hole to wellhead and the flow rate may increase or decrease during the testing. This may lead to a remarkable error if these factors were not taken into consideration. The study established new theoretic curves through Laplace transform, based on the W. B. Fair's model that considered momentum effect. And the effects of each factor on the dynamic pressure transient also were studied. |
