摘要： An embodiment of a fluid control device includes a housing, a fluid channel defined within the housing, the fluid channel having a first surface and a second surface opposing the first surface and having an inlet, and a flow control body disposed in the fluid channel, the flow control body tapering toward the inlet. The body, in use, causing fluid flowing through the channel to diverge into at least a first path between the first surface and a first side of the body, and a second path defined by at least by the second side of the body. A geometry of the first path and the second path selected is based on a subcool of the fluid at a pressure of the fluid entering the fluid channel, and the geometry is selected to induce cavitation of the fluid to choke fluid flow through the fluid channel.

摘要： A fluid control device includes a housing, a fluid channel defined within the housing, the fluid channel having an inlet, and a flow control body disposed in the fluid channel, the flow control body tapering towards the inlet. The flow control body, in use, causes a fluid flowing through the fluid channel to flow into an annular fluid flow path within the fluid channel. The annular fluid flow path has a geometry selected based on a subcool of the fluid at a pressure of the fluid entering the fluid channel, and the geometry is selected to induce cavitation of the fluid to choke fluid flow through the fluid channel.

摘要： An object including a housing, a cone movably received in the housing, a piston body attached to the cone, a valve disposed as a part of the object and separating hydrostatic pressure from pressure at an interface between the housing and the piston body, and a trigger configured to open the valve at a selected circumstance. A method for moving a selected downhole tool including running an object into a borehole, counting features in the borehole using a sensor in the object, opening the valve at a selected count, flooding the interface with hydrostatic pressure, driving the piston body away from the housing, and moving a radially expandable shoulder member toward a larger diameter end of the cone. A borehole system including a borehole in a subsurface formation, a string disposed in the borehole, and an object disposed within or as a part of the string.

摘要： A frac dart including an electric counter in the frac dart, an inductor in the frac dart, in electrical communication with the counter, the inductor generating a voltage responsive to the dart moving through a magnetic field. A method for selectively landing a dart on a landing feature in a well including sensing a landing feature by generating an inductor signal with an inductor pursuant to the inductor passing through a magnetic field associated with the landing feature in the well. generating a count in an electrical counter of the dart responsive to the inductor signal, applying a count signal to a switch of the dart based upon the count, selectively passing the count signal to an activator or an actuator of the dart based upon switch position.

摘要： An object includes a housing, a cone received in the housing, a piston body attached to the cone, a gas evolution compound disposed in the object, an interface between the housing and the piston body, an interface feed fluidly connecting the gas evolution compound with the interface, and a trigger to evolve gas from the compound at a selected circumstance. A method for moving a tool including running an object into a borehole, counting features in the borehole using a sensor in the object, evolving gas from the gas evolution compound at a selected count, pressurizing the interface with the evolved gas, driving the piston body, and moving a shoulder member toward a larger diameter end of the cone. A borehole system including a borehole in a subsurface formation, a string disposed in the borehole, and an object disposed within or as a part of the string.
