Patent number: 11578546Abstract: 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.Type: GrantFiled: August 20, 2020Date of Patent: February 14, 2023Assignee: BAKER HUGHES OILFIELD OPERATIONS LLCInventors: Eugene Stolboushkin, Alexander Kendall, Corinne Graffagnino

Patent number: 11091967Abstract: A downhole flow control configuration including a housing, a converging-diverging flow path in the housing. The flow path includes a first portion including an inlet, a converging section, and a throat section. The first portion preferentially passes a portion of a fluid having a greater subcool. The converging-diverging flow path further includes a second portion comprising a diverging section that recovers fluid pressure lost in the converging section and the throat section, and an outlet and an elongated helical flow path connected to the outlet of the converging-diverging flow path, the helical flow path producing a pressure drop in a fluid flowing therein during use.Type: GrantFiled: May 23, 2019Date of Patent: August 17, 2021Assignee: BAKER HUGHES OILFIELD OPERATIONS LLCInventors: Kousha Gohari, Oscar Becerra Moreno, Alexander Kendall

Publication number: 20210010343Abstract: A unique backup ring against ends of a sealing element features axial slots extending part way along a cylindrical segment of the backup ring. The slots end in rounded openings to relieve stress and a part of the cylindrical shape of the backup ring is solid. The slotted end of the cylindrical portion is tapered in section toward the end overlapping the sealing element. The face of the backup ring away from the sealing element is tapered and rides on an adjacent tapered surface away from the mandrel during the setting. The tapered seal end of the backup ring bends to reach the surrounding tubular before the balance of the cylindrical portion reaches the surrounding tubular. Extrusion along the mandrel is stopped by a mandrel seal on an adjacent wedge ring. The mandrel end of the backup ring has a peripheral stiffener to lend rigidity.Type: ApplicationFiled: September 25, 2020Publication date: January 14, 2021Applicant: Baker Hughes, a GE company, LLCInventors: Guijun Deng, John K.
