Apparatus and methods for preventing axial movement of downhole tool assemblies

摘要

A slip assembly apparatus is adapted (i) to be deployed into a wellbore via deployment means; (ii) to prevent axial movement of a downhole tool assembly in the wellbore when the slip assembly apparatus is actuated and external forces are imposed on the downhole tool assembly; (ii) to allow fluid flow past the slip assembly apparatus within the wellbore when the slip assembly apparatus is actuated or non-actuated; and (iii) to allow release of the slip assembly apparatus by use of a release load that is less than the axial capacity of the deployment means.
