存在井筒积液气井试井问题处理方法

井筒积液对气井井底产生一个附加压力,使试井测试资料出现异常,给气井试井资料解释带来三个难题,即地层压力计算困难、压力恢复曲线异常和产能方程异常。针对这些问题的形成原因和机理进行研究,分析其影响规律,对问题的处理方法进行分析探讨,得到了应对气井井筒积液的有效方法。用典型实例进行分析,验证了方法的实用性。

Handling Method to Gas Well Testing Problems Existing Borehole Fluid

Well-bore fluid produces an additional pressure to the bottom of the gas well,which results in testing data to be abnormal and brings three problems for data interpretation of gaswell testing,that are calculating the formation pressure is difficulties,the pressure recovery curve is abnormal and productivity equation is abnormal.By studying on causes and mechanisms of these problems,the influenced law is analyzed,the approaches to the problems are discussed,and an effective way to solve as well-bore fluid ha...
