The results show that, with the expansion cone angle remaining unchanged, the sizing length of expansion cone does not have much effect on the residual stress of casing after expansion, but it has much effect on the expansion force required by tube expansion. The expansion cone angle has no effect on the maximum residual stress of casing, but it has remarkable effect on expansion force. When the radial component force of expansion force is greater than the material's tensile strength, the damage to the material will arise.

研究结果表明，在膨胀锥锥角保持不变的情况下，膨胀锥定径长对膨胀后套管的残余应力没有太大影响，但对套管膨胀所需要的膨胀力有较大影响；膨胀锥锥角对套管最大残余应力没有影响，但对膨胀力的影响十分明显，当膨胀力的径向分力大于材料的抗拉强度时，材料将发生破坏。
