    摘要: An apparatus includes a downhole tool for conveyance in a wellbore extending into a subterranean formation. The downhole tool includes a modular cartridge assembly that includes a chassis assembly within a housing and that includes a flow line and an electrical pathway. The modular cartridge assembly includes a first connector at a first end and a second connector at a second end. The first connector and the second connector are in fluid communication with the flow line and are further in electrical communication with the electrical pathway.

    摘要: A downhole tool includes first and second collars, each including a chassis portion. A first axial load device is disposed in the first collar to exert axial force on the respective chassis portion disposed in the first collar. A second axial load device is disposed in the second collar to exert axial force on the respective chassis portion disposed in the second collar. A collar connector is coupled to the first and second collars and compresses the first axial load device.

    摘要: Three-position fluid valves for use in downhole environments are disclosed. An example valve includes first, second and third ports, a chamber coupled to the second port, a first sleeve to selectively couple the first port to the chamber and the second port, a second sleeve to selectively couple the third port to the chamber and the second port, and a piston that forms at least part of the chamber and is coupled to the sleeves. The piston moves between a first position in which the piston displaces the first sleeve to couple the first port to the chamber and the second port, a second position in which neither of the first or third ports is coupled to the second port, and a third position in which the piston displaces the second sleeve to couple the third port to the chamber and the second port.
