Abstract
Embodiments of the present disclosure are directed towards a friction reducing stabilizer. The friction reducing stabilizer includes an annular body and a plurality of blades, wherein each of the plurality of blades extends radially outward from the annular body and has a bearing mechanism configured to contact an annular down-hole component.
Claims
exact text as granted — not AI-modified1 . A friction reducing stabilizer configured to be disposed within an annular down-hole component, comprising:
an annular body; and a plurality of blades, wherein each of the plurality of blades extends radially outward from the annular body and includes a bearing mechanism configured to contact the annular down-hole component.
2 . The friction reducing stabilizer of claim 1 , comprising engagement features configured to couple between a first drill pipe segment and a second drill pipe segment.
3 . The friction reducing stabilizer of claim 1 , wherein the friction reducing stabilizer is configured to be disposed about a drill pipe.
4 . The friction reducing stabilizer of claim 1 , wherein the bearing mechanism comprises a plurality of bearing balls retained within a respective pocket of each of the plurality of blades, wherein each of the plurality of bearing balls is at least partially exposed to an exterior of the respective blade, and each of the plurality of bearing balls is configured to contact the annular down-hole component.
5 . The friction reducing stabilizer of claim 1 , wherein the bearing mechanism comprises a plurality of pockets and each of the plurality of pockets retains a bearing ball at least partially exposed to an exterior of the respective blade.
6 . The friction reducing stabilizer of claim 1 , wherein the bearing mechanism is lubricated by drilling mud or production oil.
7 . The friction reducing stabilizer of claim 1 , wherein the annular down-hole component is a casing or a liner.
8 . The friction reducing stabilizer of claim 1 , wherein each of the plurality of blades has at least one chamfered surface.
9 . The friction reducing stabilizer of claim 1 , wherein each of the plurality of blades is positioned equidistant from other blades about the annular body.
10 . The friction reducing stabilizer of claim 1 , wherein the annular body comprises at least one band configured to couple the plurality of blades to a drill pipe.
11 . A system, comprising:
a drill pipe; an annular body of a friction reducing stabilizer coupled to the drill pipe; and a plurality of blades of the friction reducing stabilizer extending radially outward from the annular body, wherein each of the plurality of blades includes a bearing mechanism configured to contact an annular down-hole component.
12 . The system of claim 11 , wherein an outer diameter of the friction reducing stabilizer is greater than a diameter of the drill pipe.
13 . The system of claim 11 , wherein the friction reducing stabilizer is configured to be coupled between a first segment of the drill pipe and second segment of the drill pipe.
14 . The system of claim 11 , wherein the annular body of the friction reducing stabilizer is configured to be disposed about the drill pipe.
15 . The system of claim 11 , wherein the annular down-hole component is a casing or a liner.
16 . The system of claim 11 , wherein the bearing mechanism of each of the plurality of blades comprises a plurality of bearing balls.
17 . The system of claim 16 , wherein the bearing balls are lubricated by drilling mud or production oil.
18 . A method for limiting friction between a down-hole component and a casing or liner, comprising:
coupling a friction reducing stabilizer to the down-hole component; positioning the down-hole component coupled with the friction reducing stabilizer within a wellbore having the casing or the liner; and translating the down-hole component coupled with the friction reducing stabilizer such that at least one bearing mechanism of the friction reducing stabilizer engages with the casing or the liner during translation of the down-hole component and limits contact between the down-hole component and the casing or the liner.
19 . The method of claim 18 , comprising rotating bearing balls of the at least one bearing mechanism along a surface of the casing or the liner while translating the down-hole component coupled with the friction reducing stabilizer.
20 . The method of claim 18 , wherein positioning the down-hole component coupled with the friction reducing stabilizer within the wellbore having the casing or the liner comprises centering the down-hole component within the casing or the liner with equidistantly spaced blades of the friction reducing stabilizer, wherein the blades extend radially outward from the down-hole component.Join the waitlist — get patent alerts
