Main Advantage & Solution

  • 1: Anchoring failure in layered production causes zonal isolation loss;
    Solution: Jaw-type slip anchoring structure, firm downhole fixation, no slip in long-term production.
  • 2: Single casing grade compatibility limits application scope;
    Solution: Adapt to multiple casing grades, meet different wellbore construction requirements.
  • 3: Complex setting operation increases downhole construction time;
    Solution: Mechanical lift-and-lower setting, simple operation, fast on-site construction.
