Finite Element Analysis of the Packer at Fracturing

Article Preview

Abstract:

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.
