摘要: An erosion resistant downhole diverter tool (210) comprises a generally cylindrical body (212) which may be configured as a slick sub or may include stabilizing blades (260). Located within the body 212 are a plurality of erosion-resistant, removable, cylindrical inserts (220). Each insert has an aperture (222) formed therein, aligned with a corresponding aperture (218) formed in the cylindrical body (212). Located within the apertures (218) in the cylindrical body (212) are pressure responsive, normally-closed valve assemblies (300), incorporating jet nozzles, which open in response to increased fluid pressure within the tool to provide fluid jets directed into the annulus surrounding the tool in a borehole or the like. The upper ends of the stabilizer blades (260) may include cutting structures to provide a back-reaming function. In alternative embodiments, the valve assemblies are omitted and replaced by simple jet nozzles, and the interior of the inserts is configured to promote fluid flow through the nozzles without increased fluid pressure. The inserts and nozzle components in contact with fluid are formed from erosion-resistant material. The tool allows fluid diversion functions to be performed without interrupting drilling operations.
