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： A screen connection area assembly configured to mount between adjacent sand screens of a gravel pack string including a body attachable to a screen connection area between two adjacent sand screens of the gravel pack string, the body configured to displace fluid and present a radial dimension between about 75% and 100% of a radial dimension of the adjacent sand screens. A method for packing a gravel pack string including disposing an assembly as in any prior embodiment on a screen connection area between adjacent sand screens of the string, running the string into a borehole, supplying a slurry to the borehole proximate the sand screens, packing the sand screens and the screen connection area between adjacent sand screens without altering a flow regime of the slurry.

摘要： Disclosed is a sealing device for use in a flow control apparatus, the sealing device comprising a static seal and a protective seal or fluid restriction. The protective seal is formed between two members formed from resilient materials being substantially resistant to wear or failure when exposed to large pressure differentials and associated jetting action. The static seal is formed using a sealing element that comprises a material that is at least partially deformable, such as an elastomer or the like. The protective seal is engaged prior to engaging or disengaging the static seal in order to prevent damage to the deformable material of the static seal.

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.
