摘要： A downhole tool having a mechanically adjustable bend angle from the surface and method for actuation of the tool. The tool includes a knuckled joint between upper and lower housing assemblies and tapered setting ring upon which the lower housing assembly bears. As the setting ring is rotated with respect to the upper housing assembly, the lower assembly is tilted. A spline sub for connection to a drill string is included, which, upon a certain weigh on bit, axially moves within the tool housing to engage the tapered setting ring and force shoes radially outward to engage the formation and hold the tool stationary. The drill string is then rotated to rotate the setting ring, and thereby alter the tool bend angle. Toggles hold the setting ring fixed to the upper housing to maintain a given bend angle during drilling operations.

摘要： A drillstring comprising a length of drillpipes and a bottomhole assembly disposed at a downhole end of the length of drillpipes. The bottomhole assembly comprises a transition section proximal to the end of the length of drillpipes to reduce vibration of the bottomhole assembly during drilling. The transition section varies gradually in acoustic impedance between the acoustic impedance of the drillstring above the transition section and the acoustic impedance of the bottomhole assembly below the transition section. The transition section forms at least thirty percent (30%) of the total length of the bottomhole assembly.

摘要： A rotational anchor mechanism is mounted on an operatively nonrotating housing that forms part of a drill string. An anchor linkage forming part of the anchor mechanism is radially extendable and contractible to move an anchor member, such as a roller, mounted on the anchor linkage radially towards and away from the housing, to engage a borehole wall for resisting rotation of the housing relative to drill pipe that is drivingly rotated within the housing. The anchor linkage includes operatively coupled mounting links mounted on the housing to pivot about respective mounting axes which are parallel to one another in a fixed spatial relationship. An actuating mechanism is coupled to the anchor linkage to exert an actuating force on the anchor linkage. An angular orientation of the actuating force relative to the housing varies in response to variation in radial expansion of the anchor linkage.

摘要： Pressure equalizers for the shaft seals of a downhole gearbox are provided. Various implementations prevent well fluid from entering a downhole gearbox through an output shaft seal, and prevent lubricating oil from leaking out of the gearbox through an input shaft seal. Small backpressure pumps may be connected to rotating shafts inside the gearbox to equalize local pressures on each side of the shaft seals. A volume compensator may communicate at a selected point along a pressure gradient in a flow tube to equalize pressures between shaft seals. Pressure tubes may be angled and transitioned in relation to a pumped fluid flow to modify fluid pressures in favor of shaft seal integrity. Sets of input and output seals may be connected by a fluid line to equilibrate pressures across all seals, and the fluid line may be favorably biased by communication with a pressure gradient in a flow tube.
