摘　　要：经对多种流行于我国试井行业的、具有行业代表性的试井专业解释书刊中的范例进行统计 ,得出表皮系数S值和井筒储集系数C值的正常分布范围分别为 - 7～ 2 0和 10 - 3～ 2。对于砂岩油气藏表皮系数值和井筒储集系数值则分别为 - 3～ 10和 10 - 3～ 1。According to the statistics of many kinds of examples in specialty and interpretation books which are popular and representative in national testing profession, the normal distribution range of S value (Skin factor) and C value (wellbore storage coefficient) is respectively -7～20 and 10 -3 ～2. For sanded hydrocarbon reservoir, it is respectively -3～10 and 10 -3 ～1. All of that provide a quantification basis for field testing interpreter to determine the formation condition near the well bore.
