Design and Performance Analysis of Mandrel Hanger Metal Sealings
In order to avoid the sealing failures of the mandrel-type casing suspension,a new metal sealing structure was designed according to the structure of the mandrel-type casing suspension and the sealing working principle.A finite element model of the sealing performance of the man-drel-type suspender was established,and the effects of different jackscrew pressures and casing suspension weights on the deformation of the sealing cone surface and contact pressure were stud-ied.The results show that with the increase of the jackscrew thrust,the average contact pressure on the upper and lower sealing cone increases,which is conducive to the realization of the sealing;with the increase of the casing suspension weight,the average contact pressure on the upper seal-ing cone increases,the average contact pressure on the lower sealing cone decreases,and the seal-ing requirements can be met except for the lower inner cone,and the results of the study provide a reference for the structural design of the sealing part of the mandrel-type suspender.
