    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.

    摘要翻译： 在本发明的一个方面，降解元件包括与烧结多晶陶瓷结合的基材。 烧结多晶陶瓷具有锥形形状和圆顶形。 当从垂直于与曲率相交的降解元件的中心轴的方向观察时，圆形顶点具有0.050至0.150英寸半径的曲率。 圆形顶点包括当圆形顶点被装载在岩层上时的特征，圆形顶点不能形成岩层，在圆顶形前面形成一个破碎的屏障，从而将圆形顶点从岩层的原始部分屏蔽，同时仍允许 圆形顶点渗透到岩层表面以下。

    摘要： In one aspect of the present invention, a drilling assembly comprises a drill bit comprising a bit body and a cutting surface. A formation engaging element protrudes from the cutting surface and is configured to engage a formation. At least one compliant member is disposed intermediate the bit body and formation engaging element and is configured to provide compliancy in a lateral direction for the formation engaging element.

    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： A drill bit has a bit body intermediate a working face and a shank end adapted for connection to a downhole drill string. The working face has at least three fixed blades converging towards a center of the working face and diverging towards a gauge of the bit, at least one blade having a cone region adjacent the center of the working face. The cone region increases in height away from the center of the working face and towards a nose portion of the at least one blade. An opening is formed in the working face at the center of the bit along an axis of the drill bit's rotation, the opening leading into a chamber with at least one wall. An indenting member is disposed within and extends from the opening, is substantially coaxial with the axis of rotation, and is fixed to the wall of the chamber.
