| 摘 要： | 经对实测深层气井井筒温度资料分析,揭示了气井不同生产状态下井筒内温度变化情况。通过分析压力、温度变化对气体压缩系数、粘度、体积系数等特性参数的影响规律,结合气藏渗流力学和热力学相关理论,建立考虑井筒热效应影响气井试井渗流模型,并通过数值求解得到新型气井试井理论图版,分析井筒热效应对气井试井曲线影响的规律。并应用实际气井资料进行了检测与验证。

| Abstract: | During gas testing process for the deep gas well,the big temperature changes in borehole causes pressure data to be abnormal.By analysis of the measured temperature data,temperature changing situations under different state of gas production have been revealed.By analyzing the influencing law from the change of pressure and temperature to the gas compressibility,viscosity,volume and other parameters,combined gas flow mechanics and the theory of thermodynamics,the well testing flow model considering heat eff... |
