| 211 | METHOD AND APPARATUS FOR CONTROLLING FLUID FLOW IN AN AUTONOMOUS VALVE USING A STICKY SWITCH | EP12767416.6 | 2012-04-04 | EP2694776B1 | 2018-06-13 | FRIPP, Michael, L.; DYKSTRA, Jason, D. |
| Apparatus and methods are described for autonomously controlling fluid flow in a tubular in a wellbore. A fluid is flowed through an inlet passageway into a biasing mechanism. A fluid flow distribution is established across the biasing mechanism. The fluid flow distribution is altered in response to a change in the fluid characteristic over time. In response, fluid flow through a downstream sticky switch assembly is altered, thereby altering fluid flow patterns in a downstream vortex assembly. The method “selects” based on a fluid characteristic, such as viscosity, density, velocity, flow rate, etc. The biasing mechanism can take various forms such as a widening passageway, contour elements along the biasing mechanism, or a curved section of the biasing mechanism passageway. The biasing mechanism can include hollows formed in the passageway wall, obstructions extending from the passageway wall, fluid diodes, Tesla fluid diodes, a chicane, or abrupt changes in passageway cross-section. | ||||||

| An apparatus is presented for autonomously controlling fluid flow in a subterranean well, the fluid having a density which changes over time. An embodiment of the apparatus has a vortex chamber, a vortex outlet, and first and second inlets into the vortex chamber. Flow into the inlets is directed by a fluid control system which has a control passageway for directing fluid flow as it exits a primary passageway. A movable fluid diverter positioned in the control passageway moves in response to change in fluid density to restrict fluid flow through the control passageway. When fluid flow through the control passageway is unrestricted, fluid from the control passageway directs fluid exiting the primary passageway toward a selected vortex inlet. When flow through the control passageway is unrestricted, flow from the primary passageway is directed into the other vortex inlet. | ||||||
