    摘要： A mechanism to enhance disengagement of release assembly portions from one another when disposed in a well. The mechanism may be disposed at an internal rod of the release assembly and configured to prevent frictional resistance to shifting of the rod. Thus, actuation of release may be assured, for example, in spite of any axial pull on the assembly which may tend to direct radial forces on the rod. As such, controlled separation of release assembly portions may be assured so as to aid in removal of a line coupled to the assembly from the well.

    摘要翻译： 当设置在井中时增强释放组件部分彼此脱离的机构。 该机构可以设置在释放组件的内部杆处并且被构造成防止对杆的移动的摩擦阻力。 因此，可以确保释放的致动，例如，尽管在组件上有任何轴向拉动，这可能倾向于在杆上引导径向力。 因此，可以确保释放组件部分的受控分离，以便有助于从井中去除与组件相连接的管线。

    摘要： A downhole tractor assembly that is configured for open-hole applications. The assembly includes a force monitoring mechanism to help monitor and control forces imparted through a drive mechanism of the tractor in real time. As such, damage to open-hole formations due to excessive tractoring forces may be minimized along with mechanical damage to the tractor. Furthermore, the drive mechanism of the tractor may include multiple sondes and bowsprings with gripping saddles specially configured for contacting the well wall across a large area in a non-point and line manner so as to avoid digging into and damaging the well wall during tractoring.

    摘要： A downhole tractor assembly that is configured for open-hole applications and of a self-aligning nature. The self-aligning nature of the assembly is effectuated through a tractor portion which is rotable about an axis of an elongated body of the assembly independent of a separate centralizing portion of the assembly. That is, the tractor portion, configured for interfacing an open-hole well wall of potentially irregular morphology, is independently rotable so as to maintain a position of substantially optimized driving friction at the interface during tractoring. Maintenance of optimized driving friction in this manner may occur irrespective of the orientation of the centralizing portion of the assembly.
