Abstract
A drill string stabilizer for use in a well bore includes a tubular body with a stabilizer axis, a first roller including a first roller axis spaced apart from the stabilizer axis of the tubular body, and at least a second roller spaced longitudinally apart from the first roller, the at least a second roller including a second roller axis spaced apart from the stabilizer axis of the tubular body. The first roller is angularly offset from the at least the second roller around a circumference of the tubular body.
Claims15
A drill string stabilizer for use in a well bore, the well bore having a well bore axis and a well bore wall, comprising:
- a tubular body with a stabilizer axis;
- a first roller including a first roller axis spaced a first fixed distance apart from the stabilizer axis of the tubular body;
- and,
- at least a second roller spaced longitudinally apart from the first roller, the at least the second roller including a second roller axis spaced a second fixed distance apart from the stabilizer axis of the tubular body;
- wherein the first roller is angularly offset from the at least the second roller around a circumference of the tubular body;
- and,
- a plenum that separates the first roller and the at least the second roller, wherein a pass-through diameter of the drill string stabilizer is smaller than a gauge diameter of the drill string stabilizer.
A drill string stabilizer for use in a well bore, the well bore having a well bore axis and a well bore wall, comprising:
- a tubular body with a stabilizer axis;
- a first stabilizing element including a first stabilizing element axis offset a first fixed distance from the stabilizer axis;
- and,
- at least the second stabilizing element spaced apart from the first stabilizing element, the at least a second stabilizing element including a second stabilizing element axis offset a second fixed distance from the stabilizer axis;
- wherein the first stabilizing element is angularly offset from the at least the second stabilizing element around a circumference of the tubular body;
- and,
- a plenum that separates the first stabilizing element and the at least the second stabilizing element, wherein a pass-through diameter of the drill string stabilizer is smaller than a gauge diameter of the drill string stabilizer.
