The sealing performance of packer under different setting pressure is studied in this paper, and the finite element analysis is carried out. Firstly, the finite model of packer is established by using ANSYS software. Different setting pressure are provided, which cause the compression change of packer rubber. The relationship between the setting pressure and the compression distance and the maximum contact stress of the packer rubber is found out by analyzing this change, including the gap between the rubber and the central pipe and the contact stress between the rubber and the inner wall of the casing. Finally, the observed phenomena and simulation data are analyzed and summarized, and the influence of the setting pressure on the sealing performance of the packer is obtained.
