摘要： A boring apparatus includes an upper member and a bit body configured to rotate relative to a pilot bit. A first end of the upper member is connected to a workstring. An inner cavity of the upper member includes a first radial cam surface. A first end of the bit body is connected to a second end of the upper member such that the bit body rotates with the upper member. A second end of the bit body includes a working face. The pilot bit includes a first end disposed within the inner cavity of the upper member, and includes a second radial cam surface configured to cooperate with the first radial cam surface to deliver a hammering force. The pilot bit extends through a central bore of the bit body, and includes an engaging surface on its second end configured to engage a formation surrounding the wellbore.

摘要： A downhole tool includes a valve assembly and a shock absorbing assembly. The valve assembly includes a valve spring operatively connected to a valve body. The shock absorbing assembly includes a spring operatively connected to a shock absorbing body having a fluid passage therethrough. The valve body is configured to selectively engage the shock absorbing body to create a fluid tight seal over the fluid passage in a first position, and to allow a fluid flow through the fluid passage in a second position. The repeated movement cycle of the selective engagement between the valve body and the shock absorbing body generates a pressure pulse or a varying pressure differential across the downhole tool. The repeated movement cycle is powered by a fluid flow. The tool may be selectively activated and deactivated.
摘要翻译：井下工具包括阀组件和减震组件。阀组件包括可操作地连接到阀体的阀弹簧。该减震组件包括可操作地连接到减震本体的弹簧，该减震本体具有穿过其中的流体通道。阀体构造成选择性地接合震动吸收体以在第一位置中在流体通道上形成流体密封，并且允许流体在第二位置流过流体通道。阀体与减震体之间的选择性接合的重复运动循环产生压力脉冲或穿过井下工具的变化压差。重复的运动循环由流体流动提供动力。该工具可以被选择性地激活和停用。

摘要： A bearing section for a mandrel at least partially disposed within an inner bore of a housing. A radial bearing and a thrust bearing are each disposed around the mandrel and within the inner bore of the housing. The radial bearing includes an outer cylindrical member, an inner cylindrical member, and a series of spherical members disposed within a space between an inner surface of the outer cylindrical member and an outer surface of the inner cylindrical member. One of the inner surface of the outer cylindrical member or the outer surface of the inner cylindrical member includes a flat profile and the other includes a series of circumferential grooves. The flat profile allows relative axial movement between the inner and outer cylindrical members without the radial bearing absorbing any thrust load.
摘要翻译：用于心轴的轴承部分至少部分地设置在壳体的内孔内。径向轴承和推力轴承分别围绕心轴并且设置在壳体的内孔内。径向轴承包括外部圆柱形构件，内部圆柱形构件以及设置在外部圆柱形构件的内表面和内部圆柱形构件的外表面之间的空间内的一系列球形构件。外圆柱构件的内表面或内圆柱构件的外表面中的一个包括扁平轮廓，而另一个包括一系列圆周凹槽。扁平型材允许内外圆柱件之间的相对轴向移动，而径向轴承不会承受任何推力载荷。

摘要： An apparatus for boring a wellbore, including a bit body having a first end, an inner cavity, and a second end. The first end is connected to a workstring that is configured to deliver a rotational force to the bit body. The inner cavity contains a profile having a first radial cam surface. The second end includes a working face containing a cutting member. The apparatus also includes a pilot bit rotatively connected within the inner cavity. A second radial cam surface is contained on a first end of the pilot bit. The first and second radial cam surfaces are operatively configured to deliver a hammering force. A second end of the pilot bit may include an engaging surface configured to engage a formation surrounding the wellbore. The bit body rotates relative to the pilot bit.
