摘　　要：对于渗透性差、产能低的气井 ,稳定测试初期往往出现井底积液 ,导致试井资料出现异常指示曲线 ,采用常规的系统试井分析方法根本无法进行处理 ,这主要是由井口压力折算井底流压的误差所引起 ,本文推导的校正分析法通过修正以上误差 ,从而可以得出该类气井稳定试井的解释结果。通过实例分析 ,验证了该方法具有较高的解释精度。To gas well of being poor permeability and low production, accumulating fluid at down hole is always appeared in early testing period which results to abnormal indicting curves of testing data that can not be processed basically by conventional system well testing analysis method. The main reason is for the error from calculating down hole flow pressure by surface pressure . the developed correct analysis way presented at paper,by correcting above errors, can get interpretation results of transient well testing to these kinds of gas wells. By applied examples analysis, it is shows that this method has a higher interpreting accuracy.
