发明名称 ROTARY STICK, SLIP AND VIBRATION REDUCTION DRILLING STABILIZERS WITH HYDRODYNAMIC FLUID BEARINGS AND HOMOGENIZERS
摘要 Apparatus and method comprising a hydrodynamic bearing disposed about a shaft and within a bore's wall with at least one periphery arced wall radially extending from and arranged about the circumference of an outer wall of a conduit shaft housing about at least one inner wall adjacent to at least one associated hydrodynamic profiled wall rotatable by or about said shaft to displace fluid axially along said at least one inner wall anchored by combined frictional engagements within the bore to force fluid between at least two of said walls and the rotating shaft to form a pressurized cushion to, in use, lubricate and dampen rotational shocks and vibrations with the shearing of said frictional engagements when bearing said rotating shaft within said subterranean bore.
