摘　　要：提出了用NiTi形状记忆合金制造井下封隔器的密封件替代传统橡胶密封件,完成了形状记忆合金密封件的结构设计,进行了形状记忆合金密封件的性能实验,并对实验结果进行了具体分析。实验证明,NiTi形状记忆合金密封件承压能力高,坐封力大,解封力较小,密封效果良好,可以代替传统的橡胶密封。This paper presents idea that packer seal made of NiTi shape memory alloy can replace traditional rubber seal. Thestructural design of seal with shape memory alloy has been completed. Experiments were conducted on functions of the seal with shapememory alloy, and results of the experiments were analyzed specifically. The experiments prove that seal with NiTi shape memory alloyhas high pressure bearing ability, powerful setting force and small releasing force, and has excellent sealing performance. Therefore, itcan replace traditional rubber seal.
