Abstract
A wear bushing includes: a wear bushing body having one or more cavities formed therein; and one or more lug cartridges each disposed within a corresponding one of the cavities in the wear bushing body. Each lug cartridge includes: a biased lug configured to be transitioned between a first position in which the lug protrudes in a radially inward direction from an inner diameter of the wear bushing body and a second position in which the lug is retracted into the corresponding cavity of the wear bushing body; and a retainer configured to retain the biased lug in the second position.
Claims27
A wear bushing, comprising:
- a wear bushing body having one or more cavities formed therein;
- and
- one or more lug cartridges each disposed within a corresponding one of the cavities in the wear bushing body, each lug cartridge comprising:
- a biased lug configured to be transitioned between a first position in which the lug protrudes in a radially inward direction from an inner diameter of the wear bushing body and a second position in which the lug is retracted into the corresponding cavity of the wear bushing body;
- and
- a retainer configured to retain the biased lug in the second position.
A lug cartridge, comprising:
- a housing with an opening formed therein;
- a biased lug disposed in the housing and configured to be transitioned between a first position in which the lug extends outward from the opening in the housing and a second position in which the lug is retained substantially within the housing, the biased lug being biased toward the first position;
- and
- a biased retainer disposed in the housing and configured to retain the lug in the second position, wherein the retainer is biased in a direction toward the biased lug.
A system, comprising:
- a running tool;
- and
- a wear bushing configured to be positioned and set in a well component via the running tool, wherein the wear bushing comprises:
- a wear bushing body having one or more cavities formed therein;
- and
- one or more lug cartridges each disposed within a corresponding one of the cavities in the wear bushing body, each lug cartridge comprising:
- a biased lug configured to be transitioned between a first position in which the lug protrudes in a radially inward direction from an inner diameter of the wear bushing body and a second position in which the lug is retracted into the corresponding cavity of the wear bushing body;
- and
- a retainer configured to retain the biased lug in the second position.
A method, comprising:
- lowering, via a running tool, a wear bushing and landing the wear bushing in a well component, the wear bushing comprising:
- a cylindrical body having a cavity formed therein;
- and
- a lug cartridge disposed within the cavity, the lug cartridge having a biased lug and a retainer;
- disengaging the running tool from the body of the wear bushing;
- collapsing the biased lug into a retracted position within the lug cartridge via movement of a ramped outer surface of the running tool against the lug;
- and
- maintaining the biased lug in the retracted position via the retainer.
