摘要： In one aspect of the invention a drill bit assembly has a body portion intermediate a shank portion and a working portion, the working portion having at least one cutting element. A shaft is supported by the body portion and extends beyond the working portion. The shaft also has a distal end that is rotationally isolated from the body portion. In another aspect of the invention, a method for steering a downhole tool string has the following steps: providing a drill bit assembly attached to an end of the tool string disposed within a bore hole; providing a shaft extending beyond a working portion of the assembly; engaging a subterranean formation with a distal end of the shaft; and angling the drill bit assembly with the shaft along a desired drilling trajectory.
摘要翻译：在本发明的一个方面中，钻头组件具有在柄部分和工作部分之间的主体部分，所述工作部分具有至少一个切割元件。轴由主体部分支撑并延伸超过工作部分。轴还具有与主体部分旋转隔离的远端。在本发明的另一方面，一种用于转向井下工具串的方法包括以下步骤：提供一钻头组件，该钻头组件安装在设置在钻孔内的工具串的端部; 提供延伸超过所述组件的工作部分的轴; 使地层与所述轴的远端接合; 并沿着所需的钻孔轨迹使钻头组件与轴倾斜。

摘要： An apparatus for degrading a paved surface includes two or more pavement degradation tools, each rotating about an axis. The pavement degradation tools are adapted to degrade a paved surface substantially normal to their axes of rotation. A linking mechanism links the rotation of the pavement degradation tools such that rotation of one causes the rotation of the other. In selected embodiments, this linking mechanism includes gears operably connected to the pavement degradation tools that rotate with the pavement degradation tool about their axes of rotation. These gears directly engage one another causing the gears, and their corresponding pavement degradation tools, to rotate in opposite directions.
摘要翻译：一种用于降低铺设表面的装置包括两个或更多个路面退化工具，每个围绕轴旋转。路面退化工具适于使基本垂直于其旋转轴线的铺设表面降解。连接机构将路面退化工具的旋转连接起来，使得一个人的旋转导致另一个的旋转。在选择的实施例中，该连接机构包括可操作地连接到路面退化工具的齿轮，该路面退化工具随着路面退化工具绕其旋转轴线旋转。这些齿轮直接相互啮合，导致齿轮及其相应的路面退化工具沿相反的方向旋转。

摘要： An apparatus for degrading and removing a paved surface is disclosed in one aspect of the invention as including a vehicle to travel across a paved surface, a pavement degradation tool coupled to the vehicle and adapted to degrade the paved surface while rotating about an axis substantially normal to the paved surface, and a vacuum device coupled to the vehicle and adapted to remove pavement fragments produced by the pavement degradation tool. The vacuum device may include several intake channels to draw in the degraded pavement fragments. In selected embodiments, these intake channels may be connected to two or more independently moveable banks.
摘要翻译：在本发明的一个方面，公开了一种用于降解和移除铺设表面的装置，包括穿过铺设表面行进的车辆，与车辆相连的路面退化工具，并且适于使围绕轴线基本正常地旋转的路面降解以及耦合到车辆并适于去除路面退化工具产生的路面碎片的真空装置。真空装置可以包括若干进气通道，用于吸收降解的路面碎片。在所选择的实施例中，这些进气通道可以连接到两个或更多个可独立移动的组。
