摘要： An excitation apparatus suitable for use downhole having interengaged masses at least in part confined or guided so as to be movable as an interengaged assembly on an axis, one mass ("rotatable mass") being rotatable relative to the other mass about the axis to cyclically vary the axial length of the assembly of the interengaged masses, a rotary drive, and an interposed spring (of any kind) between the rotary drive and the rotatable mass able to transmit torque from the rotary drive to the rotatable mass yet vary in its extent responsive to the interengaged masses.

摘要： A device in place as, or suitable for use as, a vibrational tool of or in a downhole assembly, the device having a first magnetic assembly which is to be, or can be, rotated relative to a second magnetic assembly and which, when so rotated, causes the second magnetic assembly to oscillate and/or reciprocate at least substantially in an axial manner; wherein the oscillating and/or reciprocating magnetic assembly, at least substantially, at either one end, or both ends, is attached to and constrained in its oscillations and/or reciprocation by a compliant member thereby allowing the output force to be distributed to the outer body of the vibrational tool and/or any attached uphole and/or downhole tooling, from the compression and extension of the compliant member in a substantially sinusoidal manner.
摘要翻译：一种装置就位于或适合用作井下组件的振动工具，该装置具有第一磁性组件，该第一磁性组件将相对于第二磁性组件或可以相对于第二磁性组件旋转，并且当其为使第二磁性组件至少基本上以轴向方式摆动和/或往复运动; 其中至少基本上在任一一端或两端的振荡和/或往复磁性组件通过顺应性构件附接到其并且/或由其弯曲的运动中并受其约束，从而允许输出力被分配到外部振动工具的主体和/或任何附接的井上和/或井下工具，以大致正弦的方式从柔性构件的压缩和延伸。
