Oilfield jetting tool
摘要:
A downhole jetting tool is provided for cleaning the interior of one or more hydraulic rams (14, 18) and one or more annular blowout preventers (26, 28). A unitary jetting tool body (40) has a central throughbore (42) and a plurality of radially outward jets (42, 46). A tapered landing shoulder (50) on the tool body engages a frustoconical surface of a landing ring (22) to position the tool in the well.
