摘要： An autonomous flow control device includes a valve assembly having a fluid inlet and a fluid outlet. A valve element is disposed between the fluid inlet and the fluid outlet. The valve element has a viscosity dominant flow path configured to provide a first flow resistance and an inertia dominant flow path configured to provide a second flow resistance that is greater than the first flow resistance such that when the viscosity of the fluid flowing therethrough is greater than a first predetermined level, the fluid follows the viscosity dominant flow path with the first flow resistance and when the viscosity of the fluid flowing therethrough is less than a second predetermined level, the fluid follows the inertia dominant flow path with the second flow resistance, thereby regulating the production rate of the fluid responsive to changes in the viscosity of the fluid.

摘要： An autonomous flow control device includes a valve plate having a surface and a valve element at least partially formed on the surface. The valve element has an inlet and an outlet with a fluid flow path extending therebetween. The fluid flow path included a viscosity dominant flow path configured to provide a first flow resistance and an inertia dominant flow path configured to provide a second flow resistance that is greater than the first flow resistance such that when the viscosity of the fluid flowing therethrough is greater than a first predetermined level, the fluid follows the viscosity dominant flow path with the first flow resistance and when the viscosity of the fluid flowing therethrough is less than a second predetermined level, the fluid follows the inertia dominant flow path with the second flow resistance, thereby regulating the production rate of the fluid responsive to changes in fluid viscosity.

摘要： An adaptive fluid switch for regulating the production rate of a fluid. The adaptive fluid switch includes a fluid control valve having a self-impinging valve element with at least one dissolvable plug configured to initially block fluid flow therethrough. After dissolution of the dissolvable plug and when the fluid produced through the adaptive fluid switch has a viscosity greater than a first predetermined level, the fluid follows a low resistance flow path in the self-impinging valve element but when the fluid has a viscosity less than a second predetermined level, the fluid follows a high resistance flow path in the self-impinging valve element, thereby regulating the production rate of the fluid responsive to changes in the viscosity of the fluid.
