| 摘 要： | 在油气田生产井测试时,关井早期压力和温度曲线由于受井筒相态分异的影响,出现所谓的"驼峰"效应.油井出现相态反映时,"驼峰"特征多反映在压力恢复曲线上;气井出现相态反映时,"驼峰"效应特征多反映在温度曲线上.在实际试井解释工作中,常因认识不清这两类相态分异的明显特征而影响解释结果.在分析油、气井相态分异不同特征的基础上,归纳和总结出相应的识别方法.提出的合理测试施工解决方案,可消除"驼峰"给测试解释带来的不利影响. |

| Abstract: | During well testing process for production well of oil and gas field,due to the effect of Phase Differentiation of wellbore on pressure and temperature curve at early shut-in time,a so-called hump effect is appeared.The hump feature is always reflected in the pressure recovery curve when oil well appears phase reflection,and it is reflected in the temperature curve when gas well appears phase reflection,In actual work of well testing interpretation,that of unclear this two obvious features of phase variatio... |
| Keywords: | wellbore phase production well test hump effect differentiation phase |
