摘要： An injection valve including a housing, a fluid channel in the housing, and a check valve disposed in the housing and responsive to fluid pressure in the channel to move the check valve in a direction opposite the direction of fluid flow through the channel. A method for injecting fluid into a volume including pressurizing a fluid to be injected, conveying the pressurized fluid to a space about a check valve between a check valve nose and a stem seal; and moving the check valve in a direction opposite a direction of injection fluid flow. A borehole system including a borehole in a subsurface formation, a string disposed within the borehole, and an injection valve disposed within or as a part of the string.

摘要： An embodiment of a downhole device includes an elongated body configured to be deployed in a borehole in an earth formation, the borehole including a borehole fluid. The device also includes a propulsion system attached to the body and configured to move the device through the borehole. The propulsion system includes one or more rotor blades configured to generate thrust using the borehole fluid. At least part of the one or more rotor blades is disposed external to the elongated body.
