摘要
提出了气水同产井压力恢复测试分析的数学模型，通过定义气水两相拟压力函数，对数学模型进行了简化。在获得数学模型解后，建立了气水同产井压力恢复试井资料的分析方法，并对一口气水同产井的实测压力恢复资料进行解释，获得了地层渗透率、表皮因子及地层压力，其结果的可靠程度较好，从而检验了文中提出的分析方法的合理性。
A mathematical model of pressure buildup testing analysis for gas-water well is presented in the paper, and the mathematical model is simplified by defining a function of gas-water two-phase pseudo-pressure. Based on the obtained solution of the mathematical model, an analysis method for pressure buildup data of gas-water is established. Practical pressure buildup testing data of a gas-water well were explained, and reservoir permeability, skin factor and reservoir pressure obtained, from which the results are reliable, thereby it is proved that the analysis method presented in the paper is reasonable.
