Plug assembly

A plug assembly, comprising:

• a cone assembly having a first cone end with a first cone diameter, a second cone end with a second cone diameter and a conical outer surface being between said first cone end and said second cone end and having an assembly axis, said first cone diameter being smaller than said second cone diameter, said conical outer surface being tapered from said second cone end to said first cone end;
• a sealing ring being mounted around said cone assembly, along said assembly axis and between said first cone end and said second cone end of said cone assembly, said sealing ring being radially expandable relative to said assembly axis;
• a slip device being comprised of a plurality of blades radially arranged around said conical outer surface and along said assembly axis, each blade having a first blade end and a second blade end opposite said first blade end, each blade being comprised of an angled inner blade surface and an outer blade surface opposite said angled inner blade surface, each angled inner blade surface being in sliding engagement with said conical outer surface, each blade being radially expandable relative to said assembly axis;
• a plurality of spaces defined by said plurality of blades, each space being between corresponding adjacent blades of said plurality of blades, each space being radially expandable relative to said assembly axis;
• a plurality of support lugs being positioned between said slip device and said sealing ring, each support lug being comprised of an abutment portion and a gap portion, each abutment portion being between said sealing ring and a corresponding first blade end of a corresponding blade, each gap portion being between said sealing ring and a corresponding space defined by said corresponding blade, each support lug being radially expandable relative to said assembly axis;
• and
• a setting ring being axially aligned with said slip device, said sealing ring, and said cone assembly on said assembly axis, said slip device being between said setting ring and said plurality of support lugs, said setting ring having a first setting ring end and a second setting ring end opposite said first setting ring end, said first setting ring end being in radial sliding engagement with corresponding second blade ends of corresponding blades of said slip device relative to said assembly axis,
• wherein said setting ring has a first setting distance from said cone assembly in a first setting ring position,
• wherein said setting ring has a second setting distance from said cone assembly in a second setting ring position,
• wherein said second setting distance is less than said first setting distance,
• wherein a respective gap portion of at least one support lug separates a corresponding space from said sealing ring,
• wherein a respective abutment portion of at least one support lug is positioned adjacent to said sealing ring with said setting ring at said first setting distance and at said second setting distance, and
• wherein said respective abutment portion of at least one support lug is positioned between said sealing ring and said corresponding first blade with said setting ring at said first setting distance and at said second setting distance.
