发明名称 DOWNHOLE TOOL APPARATUS WITH SLIP PLATE AND WEDGE
摘要 <p>A downhole tool that is used to seal a well bore. The downhole tool has at least one of a nose cap coupled to a slip means for converting shear forces into compression forces, a pultrusion rod, and a butterfly ring. The pultrusion rod extends the full length of the center mandrel. The butterfly ring includes a plurality of wedges configured to remove the extrusion gap when the tool is expanded to prevent failure of a sealing member over increased well bore diameters. The downhole tool includes a pressure equalization port to equalize pressure between a first and a second fluid volume during removal of the tool from the well bore.</p>
