摘要： Systems and methods for preventing slippage and rotation of components installed along a rotatable tubular shaft and/or in a tubular housing member during drilling operations are disclosed herein. The housing and/or rotatable shaft include a shoulder disposed proximate to one end. An adjustable member is secured proximate to the opposite end. One or more components are installed, covering a first portion of the surface between the adjustable member and shoulder. One or more spacing members are installed to cover substantially all of the remaining surface. The adjustable member is tightened such that the adjustable member and the shoulder apply a compressive axial load to the components and spacing members, causing frictional forces between adjacent objects greater than the torque acting on the housing and/or tubular shaft, causing each component to remain stationary with respect to the surface to which it is secured.

摘要： Systems and methods for controlling deviations during drilling operations include securing a plurality of stabilizers to a lower portion of a drill string. The stabilizers can have a substantially triangular cross-sectional area oriented perpendicular to the longitudinal axis of the drill string, and a plurality of blades secured to the stabilizer at points associated with corners of the triangular cross-sectional area. The resulting system can exhibit improved stability and stiffness, an improved flow area, a reduced annular velocity, an increased penetration rate, and a longer usable life.

摘要： Systems for controlling deviations during drilling operations, including a transmission housing and a bearing assembly secured between a stator housing and a drill bit. Two stabilizers are secured to the transmission housing, and one stabilizer is secured to the bearing assembly to provide enhanced stability to the lower portion of the drill string. The stabilizers can have a triangular shaped body for increasing flow area, reducing annular velocity, and increasing stiffness of the system. The stabilizers can be rotationally offset from one another to facilitate maintaining the gauge of the borehole. The transmission housing can be a one-piece construction to minimize connections within the system and improve reliability. The stabilizers can include laser clad metal surfaces and diamond dome inserts to prevent wear and erosion. A triangular reamer can be included beneath the stabilizers to further prevent wear to the stabilizers and to add stability to the drill bit.
