    摘要: A modular donwhole tool system with a single electric hydraulic drive assembly. The assembly includes an electric hydraulic interface for coupling to any of a variety of different modular donwhole tools. Such tools may include a plug setting actuator, sleeve shifting actuator, valve effecting actuator and a variety of other radially or axially driven hydraulically powered actuators. Indeed, a variety of different actuators may be combined within the same system, tailored based on given downhole application needs. Thus, a viable off-the-shelf modular based on-site assemblage may be available to an operator for running off of a single electric hydraulic drive assembly.

    摘要: A bias unit having a support body in use to be integrated with a drilling assembly and rotatable therewith for drilling a borehole penetrating a geological formation. A pad is pivotally connected to the support body proximate to the leading edge of the pad. A spring-driven push rod is positioned and preloaded to engage the pad, proximate to the trailing edge of the pad, and to urge the pad outward from the support body to contact the borehole wall during drilling.

    摘要: A rotatable downhole cutting tool configured for enhanced drive consistency in low power circumstances. The tool is equipped with a hydraulic axial drive actuator suitable for use in wireline deployment. The actuator itself includes a reciprocating piston with a ball screw that threadably interfaces a ball nut for dampening the axial drive imparted by the piston. As such, even though hydraulically driven at generally well under about 10 horsepower, bounce in the axial drive is substantially eliminated. This is particularly advantageous where cutting is to be applied to downhole metal based obstructions.
