Contact model construction and experimental testing of Spring-Seal sealing ring in
In order to improve the stability of the deepwater oil recovery tree working for a long time under the working condi-tions of high pressure,high temperature and low temperature,the sealing ring of oil recovery tree was redesigned,and a Spring-Seal sealing ring(hereinafter referred to as S sealing ring)was proposed.Based on the Hertzian contact theory and packing seal contact theory,the contact mechanics model of S sealing ring was reconstructed.A finite element simulation mod-el was established to analyze the sealing performance of S sealing ring under different conditions,and the reasonableness of the new contact model was verified.The actual sealing effect of S sealing ring was tested by experiments.The results show that the S sealing ring can work stably for a long time under the working conditions of high pressure,high temperature and low temperature,and the sealing performance is good.The research results can provide theoretical reference for the contact study and engineering application of S sealing ring.
