摘要： A roller reamer includes a roller assembly deployed in a corresponding axial recess in a tool body. The roller assembly is retained in the axial recess via compound wedging action provided by at least one retention assembly. One or more embodiments utilize first and second retention assemblies located at first and second axially opposed end portions of the roller assembly. The retention assembly includes first and second wedges, the first of which converts a substantially radially directed force to an axially directed force and the second of which converts the axially directed force to a cross-axially directed retention force that retains the roller assembly in the axial recess.

摘要： A pressure pulse generating tool may include an upper valve assembly disposed within the bore of a housing, where the upper valve assembly is configured to allow a fluid to flow through the upper valve assembly when in an open state. The upper valve assembly may also be configured to restrict the fluid from flowing through the upper valve assembly when in a closed state. The pressure pulse generating tool may further include a lower valve assembly disposed within the bore of the housing, where the lower valve assembly is configured to receive the fluid flow from the upper valve assembly. The lower valve assembly may also be configured to separate from the upper valve assembly in response to an increase in fluid pressure in an annulus defined between the upper valve assembly and the housing.
摘要翻译：压力脉冲发生工具可以包括设置在壳体的孔内的上阀组件，其中上阀组件构造成允许流体在处于打开状态时流过上阀组件。上阀组件还可构造成在处于关闭状态时限制流体流过上阀组件。压力脉冲发生工具还可以包括设置在壳体的孔内的下阀组件，其中下阀组件构造成接收来自上阀组件的流体流。下阀组件还可被构造成响应于限定在上阀组件和壳体之间的环形空间中的流体压力的增加而与上阀组件分离。
