Zusammenfassung: | An orienting apparatus 25 including at least one housing element 210 configured to couple with a drill string and a piston or actuator 212 disposed inside the housing element. A nozzle 211 is coupled to the piston and a torque generator 230 coupled to the piston. The torque generator extends axially downward through the housing and is configured to rotate in a first direction as it moves downward. A mandrel 260 is coupled to the torque generator and a stroke adjuster at least partially disposed in an upper end of the mandrel. Rotation in the first direction is caused by an increase in differential pressure caused by the nozzle. The apparatus may further comprise first 234 and second 236 clutches attached to the mandrel. The mandrel may include straight splines on an outside diameter configured to engage corresponding grooves on an inside diameter of the upper clutch. |
