WELL BORE CASING CUTTING TOOL HAVING AN IMPROVED BLADE STRUCTURE AND PAD TYPE STABILIZERS

摘要

A downhole cutting tool for cutting sections or "windows" in tubular strings in wellbores has rotating cutters and a lower stabilizer section, both actuated by a fluid operated mechanism. The stabilizer section keeps the downhole cutting tool centralized in the tubular string. The cutters may have a robust profile and structure which enhances the window cutting function and permits passage of an operating rod to operate the stabilizer section.
