表皮效应(skin effect)又叫趋肤效应,集肤效应，当交变电流通过导体时，电流将集中在导体表面流过，这种现象叫集肤效应。电流或电压以频率较高的电子在导体中传导时，会聚集于导体表层，而非平均分布于整个导体的截面积中。频率越高，趋肤效用越显著。
随生产时间增长，表皮效应的影响逐渐消失。
As production time increases the impact of skin effect becomes disappearing.
随生产时间增长，表皮效应的影响逐渐消失。
As production time increases, the impact of skin effect becomes disappearing.
忽略了生产井和观测井的井筒储集和表皮效应。
Wellbore-strage and skin effects at production and observation wells are neglected.
