| titleOfInvention | EXHAUST REDUCTION CYLINDER FOR SOCKET INSERTION DEVICES |
| abstract | The invention relates to an extrusion limiting ring for wellbore drilling devices in the field of oil drilling, drilling well drilling and hydrocarbon drilling, where a variety of drilling tools are used, for example, during hydraulic fracturing operations, it is necessary to seal some portions of a drilling well to allow the fluid to be pumped into the wellbore and forced to press under pressure into the underground formations around it, for which purpose the isolating devices well boreholes, such as pachers, detent shutters and fracture shutters, alternatively termed " frac " obturators. The ring according to the invention for some wellbore isolation devices (116) includes an elongate mandrel (202), a sealing element (204) disposed on the mandrel (202), and a sliding pin (206) of the mandrel (202) adjacent to the sealing member (204) and providing an outer radial surface (228); a sliding seating set (208) is circumferentially disposed around the mandrel (202) and at least a portion of the sliding wedge (206), an extrusion limiting ring (230) having an annular body providing a first end 203 a) axially, an axial second end (203 b) and a diagonal notch (308) extending at least partially between the first and second axial ends (203a and 203b), the ring (230) limiting extrusion being displaceable between a contracted state where the extrusion limitation ring (230) is disposed around the sealing element (204), and an expanded state, wherein the extrusion limiting ring (230) is disposed in around the outer radial surface (228) of the lower slide (206). |
