Actively controlled rotary steerable system and method for drilling wells

Abstract: An actively controlled rotary steerable drilling system for directional drilling of wells having a tool collar rotated by a drill string during well drilling. A bit shaft has an upper portion within the tool collar and a lower end extending from the collar and supporting a drill bit. The bit shaft is omni-directionally pivotally supported intermediate its upper and lower ends by a universal joint within the collar and is rotatably driven by the collar. To achieve controlled steering of the rotating drill bit, orientation of the bit shaft relative to the tool collar is sensed and the bit shaft is maintained geostationary and selectively axially inclined relative to the tool collar during drill string rotation by rotating it about the universal joint by an offsetting mandrel that is rotated counter to collar rotation and at the same frequency of rotation. An electric motor provides rotation to the offsetting mandrel with respect to the tool collar and is servo-controlled by signal input from position sensing elements such as magnetometers, gyroscopic sensors, and accelerometers which provide real time position signals to the motor control. In addition, when necessary, a brake is used to maintain the offsetting mandrel and the bit shaft axis geostationary. Alternatively, a turbine is connected to the offsetting mandrel to provide rotation to the offsetting mandrel with respect to the tool collar and a brake is used to servo-control the turbine by signal input from position sensors.

Rotary steerable well drilling system utilizing sliding sleeve

Abstract: An actively controlled rotary steerable drilling system for directional drilling of wells, the system having a rotary drive component rotatable within a tubular sliding tool collar that incorporates elastic anti-rotation members to maintain a coupled relation with the borehole wall during drilling. An offsetting mandrel is supported within the tool collar by a knuckle joint for pivotal movement and for rotation relative to the tool collar and has a lower end extending from the tool collar and supporting a drill bit. To achieve controlled steering of the rotating drill bit, orientation of the tool collar is sensed and the offsetting mandrel is maintained geostationary and selectively axially inclined relative to the tool collar by orienting it about the knuckle joint. An alternator and a hydraulic pump, located within the tool collar, are driven by relative rotation of the rotary drive component with the tool collar to produce electric power and hydraulic pressure for the electronics package of the tool and for actuation of hydraulic system components. Hydraulic cylinder and piston assemblies, actuated by tool position signal responsive solenoid valves, control the angular position of the offsetting mandrel with respect to the tool collar. The hydraulic pistons are servo-controlled responsive to signal input from tool position sensing systems such as magnetometers and accelerometers which provide real-time position signals to the hydraulic control system.

Endoluminal device delivery system using axially recovering shape memory material

Abstract: The endoluminal device delivery system and method for delivering an endoluminal device within a body lumen uses shape memory material in the form of a tubular collar to engage the endoluminal device during delivery to the desired location. The endoluminal device is engaged internally within the tubular collar either mechanically by crimping the tubular collar around a portion of the endoluminal device, or through an adhesive bond. The tubular collar can be crimped about a rounded portion of the stem of the endoluminal device. Once the endoluminal device is maneuvered through the body lumens to the desired location, it is decoupled from the delivery system by applying heat to the tubular collar of shape memory material. When the tubular collar has been heated to a sufficient temperature, it will transition to a rubbery state and shrink in length, thereby retracting completely back on to the optical fiber, causing the distal end of the optical fiber to engage the endoluminal device and dislodge it from the tubular collar. An interlocking assembly can also be utilized at the stem portion of the endoluminal therapeutic device to releaseably connect the endoluminal therapeutic device to the elongated pusher member. The body of shape memory material can also be bonded to both the pusher member and the endoluminal device, with the tubular collar being scored to break when the tubular collar changes from the stressed configuration to the recovered configuration. A collet can also be mounted to the pusher member and disposed within.

Anti-rattle device for receiver-style hitch

Abstract: A device for eliminating rattle in a receiver-type hitch due to movement between hitch components includes a collar, an adjustment bolt, a lock nut and a second nut. The collar has a center wall and two side walls forming a U-shaped bracket that can fit over a reinforcing lip of the hitch receiver tube. A front wall on the collar has an opening for receiving a mount shank as it enters the receiver tube. An adjustment bolt extends through the center wall to tighten the collar onto the hitch receiver tube. When the adjustment bolt is tightened, the center wall of the collar moves away upward away from the receiver tube, causing the opening in the front wall to lift the shank against the inner wall of the tube and prevent it from moving within the tube. The lock nut then holds the entire anti-rattle assembly into position. Thus, the anti-rattle device prevents hitch rattling with a minimum of components.
