摘　　要：本文分别按平面模型和空间模型,研究磨痕深度和磨痕长度对套管抗内压强度的影响。得出套管的抗内压强度是随着磨痕深度和长度的增加而降低的。同时把平面模型的结果与根据最小壁厚由API抗内压强度公式计算的结果做了比较,前者在磨损的情况下比后者要小。对于空间模型,随着磨痕长度的增加,抗内压强度趋近于一个下限值。The paper studies how the length and depth of grinding mark influence the casing burst strength in term of the areal model and space model.As a result we come to a conclusion like that an increase in the length and depth of grinding mark will decrease the casing burst strength.Meanwhile,comparing with API results,the results of areal model is less in the case of casing wear.As for the space model,the casing burst strength will tend to a lower limit value as the increase in depth of grinding mark.
