摘要： Methods of manufacturing monolithic components with complex design features and functionally graded properties in any spatial direction may include forming of outer shell with an additive manufacturing process, loading the shell with bulk material and exposing the loaded shell to a hot isostatic pressing (HIP) process. The combination of the additive manufacturing process and the HIP process forms a diffusion bond between the outer shell and the bulk material resulting in a monolithic component with functionally graded properties. The outer shell may include an exterior surface and an inner passage formed with relatively hard surfaces to accommodate fluids in a wellbore.

摘要： Steering mechanisms for use in RSS systems may be devoid of an elastomeric piston seal. Pistons of the steering mechanisms have a convex cross-section that permit the piston to pivot along with a steering pad while moving laterally or radially along a piston axis defined by a piston bore. Hydraulic pressure may be maintained as the pad is extended since a limited gap size between the piston and the bore may be maintained throughout the motion of the pistons. The pistons may be retained to the steering pad in a T-slot and may be elongated in a direction orthogonal to the axis of the piston bore. A groove may be provided around the piston for a receiving a back-up seal therein. The back-up seal may include wear resistant balls embedded in a matrix, and balls may be preloaded to serve as flow restrictors even when worn.

摘要： An actuation system to control flow of a fluid includes a body including an axial cavity and a valve in fluid communication with the axial cavity, the valve including a closing member moveable into and out of a closed position against the valve seat, and a resistance member. Fluid from the axial cavity can flow through and out of the valve when the closing member is out of the closed position and the closing member is biased into or out of the closed position by a force applied by the resistance member. The closing member is movable out of or into the closed position upon a rotational speed and fluid pressure within the axial cavity being sufficient to overcome the force applied by the resistance member.

摘要： Rotary steerable drilling systems are subjected to harsh environments including high temperature and pressure. A metallic seal ring prevents or limits erosive wear by limiting the velocity of the fluid that traversers from the high pressure side of the metallic seal ring to the low pressure side of the metallic seal ring to a value that can be sustained by the material of the metallic seal ring. A metallic seal ring is capable of withstand the wear and tear of drilling mud or other fluids used for downhole drilling operations. A metallic seal ring includes a mating configuration that creates a seal as the metallic seal ring is contracted when or a tension is applied when disposed or positioned in the piston bore. The metallic seal ring maintains an adequate seal to protect the components of a pad assembly over the life or specified duration of a downhole drilling operation.
