摘要： The sub, usable as a length element of a drill string which may include a drilling motor body, comprises three generally tubular members. Two members, each having means to attach to a continuing drill string, have threaded boxes positioned in opposition. A third member is a double ended threaded, shoulderless, pin threadedly extending into the boxes with box faces in contact when the sub is assembled. One box, and the mating pin end, have threads coarser than the finer threads in the other box and on it's mating pin end. Axial position adjustment of the pin causes the abutting box faces to change rotational relationship, thus changing the rotational relationship of axially spaced drill string elements separated by the sub. If the sub is to be used to deflect the drill string centerline, the double ended pin and the threaded boxes have a centerline tilted a small angle from the centerline of the first two members. In one configuration the assembly has, preferably, both end centerlines on one line. Manipulation as previously described rotates one end of the sub relative to the other end to cause the overall centerline of the assembly to be deflected.

摘要： An improved powered pipe tong has a frame with a generally central opening and a drive ring with pipe gripping dies arranged for rotation in the opening, about an axis. A fluid powered motor and associated gearing powers the drive ring in either direction about the axis. The dies are closed on pipe to be rotated by energy supplied by a fluid powered ram mounted in the frame and actuated to extend into the drive ring to force pipe gripping dies into gripping contact with pipe. Once the dies are forced into gripping contact with the pipe they are locked in position and the fluid powered ram is withdrawn into the frame to allow the drive ring to rotate with gripped pipe. The lock that holds the dies in closed gripping position while the drive ring rotates can be released in any position of rotating parts. The drive ring is then rotated into position for the ram to again apply force to drive ring mounted parts. If the tong has a side opening, or gap, the ram is in position to apply force when the ring and frame gaps are aligned.

摘要： A hydraulic drill string jar is powered and actuated by drilling fluid pressure controlled from the earth surface. By selective manipulation of drilling fluid flow, the jar can be conditioned to operate in drilling mode to avoid activation of the jars while normal drilling and fluid flow activities take place. By different fluid flow manipulations, the jar is conditioned to operate in the jarring mode. In the jarring mode, the jars will axially shock the drill string each time the flow rate is reduced below a preselected amount and then increased to a higher preselected amount.

摘要： A hermetic seal functions as a closure between opposite ends of the coupling by combining a metal sleeve and an elastomer sleeve extension. The metal sleeve is sealingly attached to the outer surface of one end of the coupling and the elastomer sleeve, sealingly attached to the metal sleeve, is attached at the distal end to the other end of the coupling. As an alternative, the distal end may be bonded to a second metal sleeve sealingly attached to the other end of the coupling. The seal may be convoluted, with multiple convolutions.

摘要： A flexible coupling has two spherical surfaces in rubbing contact to carry thrust, both surfaces having a common center of surface development each surface on an opposed coupling half, each coupling half having jaws extending toward the other half in an interdigitating relationship to conduct torque between the two halves, one half having a rigidly attached sleeve extending to position and support a peripheral seal for fluid tight contact with a peripheral surface on the other half to provide a fluid tight enclosure for the rubbing spherical surfaces and the surfaces of the jaws. A variable volume enclosure is provided as a lubricant reservoir and hydrostatic compensator to feed lubricant to the enclosed spherical surfaces and the surfaces of the jaws. A connecting arrangement having two flexible couplings axially separated by a connecting shaft to couple a motor rotor and motor output shaft has at least one lubricant providing reservoir arranged to provide hydrostatic compensation for the enclosed volumes of the couplings.

摘要： The apparatus has a housing arranged to function as a length of drill string, including a fluid tight fluid conducting bore, with means at each end for connecting to a continuing drill string. The housing has two principal portions bearingly connected for rotation and axial constraint. A spring loaded one way clutch connects the two portions such that torque can be conducted therethrough in only one rotational direction. The clutch has one, spring loaded, axially moving element to actuate the clutch unless locked by optional provisions. The axial movement, optionally, actuates a valve in the fluid conducting bore to create a pressure drop in the fluid stream when the clutch is disengaged to provide a pressure signal that can be detected at the surface to indicate that the clutch is disengaged.

摘要： The housing of the orienting motor serves as a length of pipe string and rotates the lower end relative to the upper end. Rotation is in preselected increments each time the rate of fluid flow in the pipe string is changed between preselected limits. Once rotated an increment the housing is rotationally locked as long as flow rate is maintained greater than a preselected amount. When fluid flow is stopped, the actuation system resets, in time, to the starting position but a one way clutch retains the previous rotational relationship between opposite ends of the housing. Resetting time is adjustable to permit a preselected activity period before flow restart without further changes in the orienting action.

摘要： A general housing encloses a drilling motor that can be disabled to permit optimum rotary drilling practice. A mode selector responds to manipulation of the drilling fluid flow rate and permits activation of the drilling motor to drive a drill bit. The general housing is a two part arrangement that is connected by a deflection arrangement that is activated by start-up of the motor. A one-way clutch allows the lower housing to drive the drill bit when the motor is disabled and the clutch, with drill bit rotation resistance, changes the deflection arrangement for straight rotary drilling when the drill string is rotated.

摘要： The drill string is fitted for drilling activity in the formation expected, including a jet nozzle equipped drill head, and a near bit kick sub. The drill string is deflected to change the progressing well bore to a preferred direction. After the change in well bore direction is accomplished by jetting, the kick sub is straightened and drilling proceeds along the new well bore center line. Ideally, the kick sub responds to direction from the surface and produces a change in drilling fluid pressure at the surface to indicate which mode, straight or deflected, is being carried out down hole.
