Claims20
A system, comprising:
- an annular seal, comprising:
- an annular seal jacket, wherein the annular seal jacket comprises an annular base, first and second annular walls coupled to the annular base, and an annular chamber disposed between the first and second annular walls;
- a first spring disposed in the annular chamber;
- a second spring disposed in the annular chamber;
- a first spacer disposed between the first spring and the second spring;
- a second spacer disposed between the second spring and the annular base;
- a backup ring disposed against the annular base opposite the second spacer;
- and
- an insert configured to bias the first and second springs in the annular seal jacket, wherein the insert comprises one or more pressure balancing passages, and the one or more pressure balancing passages comprise a transverse passage in an axial portion of the insert.
6 more elements
A system, comprising:
- a first annular body comprising an outer annular recess;
- a second annular body sized to be run into the first annular body;
- and
- an annular seal positioned at least partially within the outer annular recess and comprising:
- an annular seal jacket, wherein the annular seal jacket comprises an annular base, first and second annular walls coupled to the annular base, and an annular chamber disposed between the first and second annular walls;
- a first spring disposed in the annular chamber;
- a second spring disposed in the annular chamber;
- a first spacer disposed between the first spring and the second spring;
- a second spacer disposed between the second spring and the annular base;
- a backup ring disposed against the annular base opposite the second spacer;
- and
- an insert configured to bias the first and second springs in the annular seal jacket, wherein the insert comprises one or more pressure balancing passages, and the one or more pressure balancing passages comprise a transverse passage in an axial portion of the insert, and
- wherein the first annular body further comprises an outer surface having a taper configured to drive the annular seal into a seal pocket formed between the first and second annular bodies when the second annular body is run into the first annular body.

A method, comprising:
- positioning an annular seal at least partially within an outer annular recess of a first annular body and comprising:
- an annular seal jacket, wherein the annular seal jacket comprises an annular base, first and second annular walls coupled to the annular base, and an annular chamber disposed between the first and second annular walls;
- a first spring disposed in the annular chamber;
- a second spring disposed in the annular chamber;
- a first spacer disposed between the first spring and the second spring;
- a second spacer disposed between the second spring and the annular base;
- a backup ring disposed against the annular base opposite the second spacer;
- and
- an insert configured to bias the first and second springs in the annular seal jacket, wherein the insert comprises one or more pressure balancing passages, and the one or more pressure balancing passages comprise a transverse passage in an axial portion of the insert;
- running a second annular body into the first annular body;
- and
- driving the annular seal along a taper formed in an outer surface of the first annular body and into a seal pocket formed between the first and second annular bodies.
