摘要: 表皮系数是识别和诊断地层伤害程度中最重要的参数,它的大小直接反映地层伤害和产能损失情况。根据试井解释模型的假设条件,提出试井解释出的表皮系数必须进行修正分解才能正确地评价储层伤害程度,推导出总表皮数的表达式和每项表皮系数的计算公式,通过实例分析表明地层伤害程度的定量分析是十分有效的,为钻井、完井、试油和增产过程的伤害评价提供了一种可行的办法。

Abstract: Skin factor is the most important parameter that diagnoses and identifies formation damage, and also reflects loss of oil well production. According to well testing assumption, the paper suggests skin factor from well testing that will be recollected and annualized, also give out calculation formulation. By examples,quantitative evaluation of formation damage is very good. It is
feasible method that is evaluation of formation damage in drilling, completion and stimulation.

Key words: reservoir evaluation, skin factor, quantitative analysis
