Abstract
A stabilizer assembly comprising a tubular member, a stabilizer sleeve slidably disposed about the tubular member, and a plurality of round members each disposed between the stabilizer sleeve and the tubular member. The stabilizer sleeve may comprise a plurality of round cavities each located in an inner surface of the stabilizer sleeve. Each of the plurality of round members may be disposed within a corresponding one of the plurality of round cavities. The stabilizer assembly may be coupled between opposing first and second portions of a downhole drill string.
Claims7
An apparatus, comprising:
- a stabilizer assembly coupled between opposing first and second portions of a downhole drill string, wherein the stabilizer assembly comprises:
- a tubular member;
- a stabilizer sleeve slidably disposed about the tubular member and comprising at least one first round cavity located in an inner surface of the stabilizer sleeve;
- and
- at least one round member disposed between the stabilizer sleeve and the tubular member, within the at least one round cavity, so as to contact both of the stabilizer sleeve and the tubular member, wherein the tubular member comprises at least one second round cavity located on an outer surface of the tubular member;
- and
- the at least one round member is at least partially disposed with the at least one first round cavity and the at least one second round cavity, wherein the at least one second round cavity has a second radius of curvature that closely fits a radius of curvature of the round member and wherein the at least one first round cavity has a first radius of curvature that is greater than the second radius of curvature and does not closely fit the radius of curvature of the round member.
