Abstract

Completion packer slips have the effect of supporting the packer by anchoring and locking packer rubber in high temperature and high pressure (HPHT) wells, which are an important component for ensuring the reliability of the packer. There are interactions when slips and casing contact with each other, which would generate interactive forces, and the supporting forces of slips mainly relay on the interactions between slips and casing. In this paper, the interactions between slips and casing have been studied by theory and finite element method based on ANSYS. The depth of slip bit into casing and the rules of interaction between slips and casing were found from above research. It was found that the bite depth of HPHT completion packers was generally about 0.7 mm. And, the load acted on the slip elements tip will increase with the increase of the axial load acted on the cone, while decrease with the slip elements number.
