FEM Analysis of Plug Packer Based on the Model of Mooney-Rivlin
The technology of Pipeline high-pressure intelligent isolation is a new technology which has been developed by Company PSI since the 1990’s, and the core technology, packer’s sealing performance has been blocked from then on. In this paper, we study the Polyurethane columns specimen of different hardness though ANSYS, then fit with the curve from the experiments, in order to get the Polyurethane columns’ Mechanical constants of Model Mooney-Rivlin. Calculate the deformation between two statuses, then according to isolation pressure and anti-convexity of packer we choose the packer of appropriate hardness. Finally, analysis the packer under different pressure, get the working curve of isolation ability, and the outlet can be used in the design of packer.
