Slip Configuration for Downhole Tool

摘要

A downhole tool or plug is used for sealing in tubing. A mandrel of the tool has a first shoulder disposed toward a downhole end of the mandrel. A sealing element for sealing in the tubing is disposed on the mandrel adjacent the first shoulder, a slip is disposed on the mandrel adjacent the sealing element, and a cone is disposed on the mandrel adjacent the slip. In setting the tool, the cone moves toward the first shoulder, wedges the slip against the tubing, and compresses the sealing element between the slip and the first shoulder. Force applied against a seated plug in the mandrel transfers through the mandrel to the cone and slip without passing through the sealing element, which avoids detrimental effects.
