摘　　要：本文通过油井实例对表皮系数进行计算及对总表皮系数进行分解分析。油井测试获得的表皮系数是各种因素产生的表皮效应的总和,是评价油气井产能和完井效率的重要参数。为获得地层真实伤害表皮系数,便于分析地层伤害原因,本文提出将表皮系数进行分解,然后以真实表皮系数为依据确定地层伤害程度,以此指导储层改造实践并为改造效果预测提供可靠依据。In this paper,skin factor is calculated and the total skin factor is made decomposition analysis through the example of oil wells.Skin factor which is gotten by oil well testing is the sum of the skin effect of various factors,is the important parameters for the evaluation of oil gas well production capacity and completion efficiency.In order to obtain the true formation damage skin factor,and analyze the causes expediently,this paper presents the decomposition of the skin factor,then determines the degree of formation damage on the basis of the true skin factor,to guide the practice of reservoir stimulation and provide a reliable basis for the transforming effect prediction.
