Abstract
Official abstract text for this publication.
An example downhole tool may include a first component and a second component. A first seal may be positioned between the first component and the second component, and a first energizer may be positioned between the first seal and the first component. The first seal may comprise a polyaryletherketone (PAEK) material. The first energizer may be a compressible material. The PAEK material may be at least one of polyetherketone (PEK), polyether ether ketone (PEEK), polyetherketoneketone (PEKK), polyehtheretherketoneketone (PEEKK), and polyetherketoneether-ketoneketone (PEKEKK).
First claim
Opening claim text (preview).
What is claimed is: 1. A downhole tool comprising a first component of the downhole tool comprising a tool body that includes a recessed portion and a hydraulic fluid chamber within the recessed portion; a second component of the downhole tool comprising a hatch or cover positioned over the recessed portion; a first seal positioned between the first component and the second component and comprised of a polyaryletherketone (PAEK) material; and a first energizer positioned between the first seal and the first component, wherein the first seal and first energizer provide a hermetic and fluid-resistant seal between the first component and the second component. 2. The downhole tool of claim 1 , further comprising a second seal positioned between the first seal and the second component; and a second energizer positioned between the second seal and the second component, wherein the first seal and first energized and second seal and second energizer provide a hermetic and fluid resistant seal between the first component and the second component. 3. The downhole tool of claim 2 , wherein the second seal comprises at least one of PAEK material and/or metal. 4. The downhole tool of claim 1 , wherein the first seal comprises at least one planar or flat surface in contact with the second component. 5. The downhole tool of claim 1 , wherein the first seal comprises at least one first planar or flat surface; the second seal comprises at least one second planar or flat surface; and at least one first planar or flat surface is in contact with the at least one second planar or flat surface.
