Oil Downhole Drilling Tools Non - Rotating Stabilizer 5 3 / 4 '' ~ 28''

Downhole Drilling Tools Non-Rotating Stabilizer, 5 3/4''~28''​

A non-rotating stabilizer tool is provided for connection within a drilling string for stabilization and centralization of the drill string within a well bore being drilled by a rotary drill bit. The tool incorporates an elongate stabilizer and centralizer mandrel having upper and lower collars for its connection within the drill string. The mandrel defines an external circumferential stabilizer receptacle having a cylindrical surface and upper and lower shoulders which are lined with a wear resistant low friction material. The mandrel defines a plurality of axially spaced circumferential seat grooves which interrupt the cylindrical receptacle surface and the friction resistant lining. A stabilizer is rotatably mounted within the stabilizer receptacle by a plurality of wear pads that are seated within the circumferential seat grooves and provide rotatable support for the stabilizer with its inner periphery disposed in spaced relation with the lining of the stabilizer receptacle. During normal drilling operations the stabilizer is essentially static within the well bore with the mandrel being rotated within the stabilizer by the drill string. Externally the stabilizer defines helical lands and grooves which define fluid courses, with the lands being provided with a hard facing material to minimize wear thereof as the stabilizer is moved linearly within the well bore.
