초록 ▼

A flow control device, including a first member defining a first portion of a flow path and a second member defining a second portion of the flow path. The flow path has a cross sectional flow area defined at least partially by the first member and the second member. A length of the flow path is greater than a largest dimension of the cross sectional flow area, and the cross sectional flow area is adjustable by movement of at least a portion of the first member relative to the second member. A crush zone arranged with at least one of the first member and the second member that can change in length due to loading thereof. A method of adjusting restriction of a flow path is also included.

대표청구항 ▼

1. A flow control device, comprising: a first member defining a first portion of a cross section of a flow path;a second member defining a second portion of the cross section of the flow path, the second member being distinct from and operably coupled with the first member, the flow path having a cross sectional flow area defined at least partially by the first portion and the second portion, a length of the flow path being greater than a largest dimension of the cross sectional flow area, and the cross sectional flow area being adjustable by axial movement of at least a portion of the first member relative to the second member; anda crush zone arranged with at least one of the first member and the second member that can change in length due to loading thereof, at least a portion of the crush zone being configured to undergo plastic deformation due to the loading thereof and resulting in the movement of at least a portion of the first member relative to the second member. 2. The flow control device of claim 1, wherein the cross sectional flow area is altered at every point along the flow path in response to the movement. 3. The flow control device of claim 1, wherein the first member is tubular with a radially inwardly protruding thread and the second member is tubular with a radially outwardly protruding thread and the radially outwardly protruding thread extends radially outwardly a dimension greater than a minimum dimension of the radially inwardly protruding thread. 4. The flow control device of claim 3, wherein clearance between the radially inwardly protruding thread and the radially outwardly protruding thread defines the flow path. 5. The flow control device of claim 1, wherein a plurality of the flow control devices are incorporated in a well to equalize at least one of injection of steam and production of hydrocarbons along the well. 6. The flow control device of claim 1, wherein the at least one crush zone changes in axial length in response to axial loading thereof. 7. The flow control device of claim 1, wherein the at least one crush zone includes at least one shear joint. 8. The flow control device of claim 1, wherein the crush zone includes at least one convolute. 9. The flow control device of claim 1, wherein the device is arranged downhole. 10. A flow control device, comprising: a first member defining a first portion of a cross section of a flow path;a second member defining a second portion of the cross section of the flow path, the second member being distinct from and operably coupled with the first member, the flow path having a cross sectional flow area defined at least partially by the first portion and the second portion, a length of the flow path being greater than a largest dimension of the cross sectional flow area and the cross sectional flow area being adjustable by movement of at least a portion of the first member relative to the second member; anda crush zone arranged with at least one of the first member and the second member that can change in length due to loading thereof, at least a portion of the crush zone being configured to undergo plastic deformation due to the loading thereof and resulting in the movement of at least a portion of the first member relative to the second member,wherein the flow path has a helical shape. 11. A method of adjusting restriction of a flow path, comprising: porting fluid through the flow path, the flow path having a length greater than a largest dimension of a cross sectional area of the flow path; andaltering the cross sectional area of the flow path by loading a crush zone to plastically deform at least a portion of the crush zone thereby changing an alterable length of the crush zone, the crush zone arranged with at least one of a first member defining a first portion of a cross section of the flow path and a second member, distinct from and operably coupled with the first member, defining a second portion of the cross section of the flow path, the loading of the crush zone resulting in axial movement of the first member relative to the second member such that the cross sectional area is altered. 12. The method of adjusting restriction of a flow path of claim 11, further comprising shortening the crush zone arranged with the at least one of the first member and the second member. 13. The method of adjusting restriction of a flow path of claim 12, wherein shortening the crush zone includes compressing at least one convolution of the crush zone. 14. The method of adjusting restriction of a flow path of claim 12, wherein shortening the crush zone includes shearing at least one shear joint of the crush zone. 15. The method of adjusting restriction of a flow path of claim 11, wherein loading the crush zone includes axially loading the crush zone. 16. The method of adjusting restriction of a flow path of claim 11, further comprising arranging a tubular string containing the first member and the second member downhole.
