Abstract

The slip is the core component of the permanent packer, and its performance affects the anchor reliability of the packer directly. The slip of the permanent packer is used to anchor the casing and lock the packer. The slip structure is especially important for the sealing performance of the packer. The research methods of laboratory tests and numerical simulation are combined to improve the overall performance of the permanent packer. First of all, the scheme of the laboratory tests is designed, the anchor load range of the permanent packer slip is obtained, and the reliability of the anchor is verified. Taken the setting load of laboratory tests for as the simulation boundary conditions, the values of the first, the second, the third critical fracture stress of the permanent type packer slip are obtained by numerical simulation software LS-DYNA, meanwhile the trends of expansion of cracks and fracture morphology are well known. Comprehensive analysis of laboratory tests and numerical simulation results show that: packer setting anchor effect is good under the condition of 30MPa setting load, and slip fracture morphology in laboratory tests is consistent with the results of numerical simulation. The accuracy of the numerical simulation analysis provides scientific basis for slip structure design of the permanent packer.
