摘　　要：产能测试资料分析方法基本包括两类三种,即二项式和指数式产能分析的压力分析方法、压力平方分析方法和拟压力分析方法。由于各气田的地质情况不同,尤其是地层压力不同,在实际应用中存在一定的混乱状况。从气体渗流的基本微分方程出发,论证了压力分析方法、压力平方分析方法和拟压力分析方法的适用范围。运用根据三种形式的气体渗流微分方程建立的三种形式的产能评价方法,即拟压力法、压力法、压力平方法三种产能评价方法,对高压气井的产能进行评价分析,分别对比了其绝对误差和相对误差。通过分析认为,在对高压气井进行产能评价时,拟压力方法是精确的;压力方法存在一定的误差,但误差不大;压力平方法存在误差,且误差较大,不应用其对高压气井进行产能评价。The analysis method of deliverability test data basic includes two types and three kinds,namely the binomial and exponential capacity analysis of stress analysis method,pressure square analysis method and analysis method. Due to the different geology situations of each gas field,especially the formation pressure,there is confusion in practice application. Starting from the basic differential equation of gas seepage,the applicable scope the stress analysis method,pressure square analysis method and analysis method are demonstrated.By using three types of production capacity for evaluation methods,namely the pseudo-pressure method,pressure method and pressure square analysis method,on the basis of three forms of gas seepage differential equations,production capacity for the high pressure gas well is analyzed,absolte error and relative error are contrasted respectively. Through analysis,it is thought that,pseudo-pressure method is accurate when evaluating production capacity for the high pressure gas well,pressure method has certain error,but not be much,and the pressure square method has error and the error is bigger,should not be used to conduct production capacity evaluation for the high pressure gas well.
