摘要
变表皮对试气资料的影响是一个不容忽视的问题。结合张士奇等人提出的层间干扰在气井中产生的条件及其对试气资料的影响展开讨论，指出是变表皮（而不是层间干扰）导致二项式产能关系图反向。推荐了在中、低渗储层的气井进行合理的产能试井类型应是等时（或修正等时）试井。应利用不同工作制度下的流压、流量确定产能和产能方程来评价受变表皮影响的产能试井资料，并在资料分析前，对试井作业质量及测试条件进行严格检查。
The effect of Changing skin on the gas production test is a serious problem. Based on the interlayer interference condation and its effect on gas production test, we point out hat changing skin is the main factor for quadratic oroductivity expression Changing. We recommened that the reasonnable gas production test typeis isochronol test or modified isochrononl test. Under different working condation,using flowing pressure and rate to evaluate the changing skin is the right method. Be fore the date analysis, it is important to verify the test work and teat condation.
