摘要： In one aspect of the present invention, a drill bit assembly for downhole drilling comprises an outer bit comprising a central axis and an outer cutting area and an inner bit disposed within the outer bit and comprising an inner cutting area. The outer bit comprises a first plurality of cutting elements and the inner bit comprises a second plurality of cutting elements wherein an average distance of each cutting element in the first plurality to the central axis forms a first moment arm and an average distance of each cutting element in the second plurality to the central axis forms a second moment arm. A ratio of the inner cutting area to the outer cutting area is substantially equal to a ratio of the outer moment arm to the inner moment arm.

摘要： What is claimed is a downhole lubrication system comprising a drill string component comprising an outer diameter and an inner bore. A reservoir may be disposed intermediate the outer diameter and inner bore. A piston may be disposed at least partially within the reservoir. At least one channel may extend from the reservoir to a bearing surface. As drilling fluid is passed through the inner bore, the piston may be pressurized, urging lubricant toward the bearing surface via the at least one channel.

摘要： In one aspect of the present invention, an energy storage system has an elastic hydraulic fluid vessel with an internal variable volume and being coupled to a hydraulic rotary mechanism. The elastic hydraulic fluid vessel has an elastic material adapted to store a potential energy within its fibers when the internal volume is increased by a hydraulic fluid. The hydraulic rotary mechanism is adapted to be accelerated by the release of the potential energy of the fibers of the elastic vessel by ejecting the hydraulic fluid from the internal variable volume into the rotary mechanism.

摘要： In one aspect of the invention, a degradation element includes a substrate bonded to a sintered polycrystalline ceramic. The sintered polycrystalline ceramic has a tapering shape and a rounded apex. The rounded apex has a curvature with a 0.050 to 0.150 inch radius when viewed from a direction normal to a central axis of the degradation element that intersects the curvature. The rounded apex includes the characteristic of when the rounded apex is loaded against a rock formation, the rounded apex fails the rock formation forming a crushed barrier ahead of the rounded apex that shields the rounded apex from a virgin portion of the rock formation while still allowing the rounded apex to penetrate below a surface of the rock formation.
