| 摘 要： | 通过数值计算讨论了水泥环弹性模量、水泥环厚度、套管壁厚、不同接触条件等因素对套管和水泥环外载平均水平及非均匀程度的影响．结果表明，水泥环弹性参量对套管及水泥环受力影响很大，水泥环厚度、套管壁厚对自受力分布影响较大，不同接触状况对外载分布均有不同程度的影响

| Abstract: | By the use of energy method, buckling critical load in inclined hole is obtained, and a mechanical model is presented. In the mechanical model, dead weight of drill string and inclined angle of well are considered, and the general forms of critical load are given. The difference in two expressions of deformed energy increment is discussed. The results can be applied in engineering calculation. |
