气井修井中压井方法的选用与计算

气井修井作业中，如何确立压井参数选择压井方法，对高压气井修井作业举足轻重。文中以渗流力学为基础，建立地层流体的渗流数学模型，进行理论分析，确定气井修井中压井参数的理论依据。认为：试修作业中，高压气井必须选择好压方法，同时要配备好的循环设备和确定科学的压井参数。

Selection and calculation of kill method in gas well workover

During gas well workover treatment with high pressure,it is very important to determine kill parameter and select kill method.In this paper,on the basis of percolation mechanics,percolation mathematical model is established and analysed.Theoretical basis of kill parameter is got in gas well workover.Three kill methods are proposed in high pressure gas well workover that are filling method,circulating method and squeezing method,and they are analysed by examples.The results show that high pressure gradient gas wells must select good kill method,equip good circulating device and determine scientific kill parameter in workover treatment.
