The rubber tube is made of rubber material. It is the important part of the orifice boP. The rubber tube is squeezed and deformed to contact with the drill pipe to achieve the sealing function. There are large deformation and contact problems in the sealing process of rubber, which is difficult to calculate theoretically. In this paper, finite element analysis software is used to analyze the contact stress between the designed rubber cylinder and the drill pipe under different loads and the influence of friction factor on the contact stress. The influence rules are summarized, the structure of the rubber cylinder is optimized, and the contact stress of the optimized rubber cylinder is analyzed. The results meet the design requirements.

Thrust bearing is one of the most important components in esPCP system, which determines the lifespan of the whole system under the restriction of some factors such as the depth of downhole unit, the viscosity of petroleum oil to be pumped. To increase the high temperature bearing ability of the bearings under the limitation of radial size, the damage reason of pre-applied bearings was analyzed. Some different modified plans were put forward from two aspects of structure and material. Contact problems were researched for different plans with finite element analysis software of ANSIS. Comparison of results shows that, in the well of 5½" tube, the optimum selection is ball thrust bearing with 8 balls of radial size of 10mm without keeper.

According to the working principle and structural feature of compressive packer, mechanic analysis of rubber tubes was done with adopting Mooney-Rivlin model. The contact stress between rubber tube and the casing and axial compression distance were figured out at 83MPa of the differential pressure between inside and outside string. The results show that the middle tube has the function of beginning to set the paker and the lower tube seals and separate the layers. Upper tubing should be installed the equipment to prevent shoulder protruding.
