| 摘 要： | 根据抽汲井试井工艺过程及其特点,采用已知上一次抽汲结束时的地层压力分布规律建立下一次抽汲数学模型的方法,建立了抽汲井试井分析数学模型,并在Laplace空间求解出了相应的精确解。将这一成果应用于长庆油田之中,结果表明:该理论能描述抽汲井的井底压力瞬变性及抽汲期井底压力变化无规律性的特征,符合实际测试工艺情况,弥补了抽汲井试井这一空白;提高了该类井试井的解释率和解释结果的可信度。同时,利用该理论还可计算抽汲过程中任一时刻的井底压力和关井时刻的井底压力,解决了抽汲井难以计算关井时刻井底压力的问题。

| Abstract: | According to the technical procedures and the characteristics of well -testing for a swabbing well and the formation pressure distribution of last swabbing, we developed a new mathematics model of well-testing analysis for the next step swabbing, and obtained the theoretical solution for this new model in Laplace space. Application results in Changqing oil field showed that this new model can describe the characteristics of transient drops of the well pressure in swabbing producer and the changes of the non- regularly characteristics of the well pressure during the swabbing procedures. The ratio of the well -testing data is used and the reliability of the analysis results can be also increased. The well pressure of a swabbing producing well can be calculated with this new model as well. |
