Abstract

Official abstract text for this publication.

An annular restrictor for use in a well can include a body which extends circumferentially about a tubular mandrel, and a section which, in cooperation with the body, restricts fluid flow through an annulus, a line being secured between the body and the section. A method of completing a well can include installing a line in an annular restrictor, and restricting fluid flow through an annulus, with the restricting being performed by the annular restrictor interconnected between steam injection valves. A method of attaching a line to a tubular string for use in a well can include covering the line with a section of an annular restrictor, and securing the section to a body of the annular restrictor, each of the section and the body having a flow restricting surface formed thereon, and the covering and securing steps being performed without splicing or making a connection in the line.

First claim

Opening claim text (preview).

What is claimed is: 1. An annular restrictor for use in a subterranean well, the annular restrictor comprising: a body which extends circumferentially about a tubular mandrel, the body comprising a slot extending longitudinally along an outer surface of the body; and a section which fits into the slot, wherein the body and the section together form a cup-shaped end of the annular restrictor, and wherein at least one line is secured between the body and the section such that the at least one line can be longitudinally displaced with respect to the body and the section of the restrictor as situated in the subterranean well. 2. The annular restrictor of claim 1 , wherein at least one line-receiving recess is formed on at least one of the body and the section. 3. The annular restrictor of claim 2 , wherein the line-receiving recess is formed on both of the body and the section. 4. The annular restrictor of claim 1 , further comprising a clamp which secures the section to the body. 5. The annular restrictor of claim 1 , wherein each of the body and the section includes a flow restricting surface. 6. A method of completing a subterranean well, the method comprising: laterally installing at least one line in an annular restrictor; then covering the line with a section of a cup end of the annular restrictor; then securing the section to the annular restrictor to allow for longitudinal displacement of the same; and restricting fluid flow through an annulus formed radially between a tubular string and a well bore via the annular restrictor, wherein the section is secured to a body of the annular restrictor via a clamp, and wherein the section cooperates with the body in restricting fluid flow through the annulus. 7. The method of claim 6 , wherein at least one of the body and the section has a line-receiving recess formed thereon. 8. The method of claim 6 , wherein each of the body and the section includes a flow restricting surface. 9. A method of attaching at least one line to a tubular string for use in a subterranean well, the method comprising: laterally installing the line in an annular restrictor; then covering the line with a section of the annular restrictor; and then securing the section to a body of the annular restrictor, wherein the section and the body together form a circumferential cup-shaped flow restricting surface, and wherein the covering and the securing are performed without splicing or making a connection in the line, wherein the securing further comprises clamping the section to the body. 10. An annular restrictor for use in a subterranean well, the annular restrictor comprising: a body which extends circumferentially about a tubular mandrel, the body comprising a slot extending longitudinally along an outer surface of the body; and a section which fits into the slot and which, in cooperation with the body, forms a cup-shaped restriction to fluid flow through an annulus in the well, at least one line being secured between the body and the section, wherein at least one line-receiving recess is formed on both of the body and the section and permits longitudinal displacement of the at least one line with respect to the body and the section of the restrictor as situated in the subterranean well. 11. The annular restrictor of claim 10 , wherein the body and section form a cup shape circumscribing the at least one line-receiving recess. 12. The annular restrictor of claim 10 , further comprising a clamp which secures the section to the body. 13. The annular restrictor of claim 10 , wherein each of the body and the section includes a flow restricting surface. 14. A method of attaching at least one line to a tubular string for use in a subterranean well, the method comprising: laterally installing the line in an annular restrictor; covering the line with a section of the annular restrictor to permit longitudinal displacement of the line; and securing the section to a body of the annular restrictor, each of the section and the body forming a corresponding portion of a circumferential cup-shaped flow restricting surface, wherein the covering and the securing are performed without splicing or making a connection in the line, and wherein the annular restrictor is interconnected between steam injection valves, wherein the securing further comprises clamping the section to the body.
