每单位流速下的井内压降受地层阻力、流体粘度以及由所采用的钻井和完井技术以及可能由所采用的生产实践产生的集中在井筒周围的附加阻力的控制。本文将这种附加阻力引起的压降定义为集肤效应，用符号S表示。这种表皮效应大大降低了油井的生产能力。给出了定量确定（a）S值、（B）最终恢复压力和（c）平均渗透率乘以产层厚度的乘积的方法。
The pressure drop in a well per unit rate of flow is con· trolled by the resistance of the formation, the viscosity of the fluid, and the additional resistance concentrated around the well bore resulting from the drilling and completion technique employed and, perhaps, from the production practices used. The pressure drop caused by this additional resistance is defined in this paper as the skin effect, denoted by the symbol S. This skin effect considerably detracts from a well's capacity to produce. Methods are given to determine quantitatively (a) the value of S, (b) the final build-up pressure, and (c) the product of average permeability times the thickness of the producing formation.
