摘要： A method and apparatus for transmitting information to the surface from down hole in a well in which a pulser is incorporated into the bottom hole assembly of a drill string that generates pressure pulses encoded to contain information concerning the drilling operation. The pressure pulses travel to the surface where they are decoded so as to decipher the information. The pulser includes a stator forming passages through which drilling fluid flows on its way to the drill bit. The rotor has blades that obstruct the flow of drilling fluid through the passages when the rotor is rotated into a first orientation and that relieve the obstruction when rotated into a second orientation, so that oscillation of the rotor generates the encoded pressure pulses. An electric motor, under the operation of a controller, drives a drive train that oscillates the rotor between the first and second orientations. The electric motor is located in an air-filled chamber whereas the major portion of the drive train is located in a liquid-filled chamber. The controller controls one or more characteristics of the pressure pulses by varying the oscillation of the rotor. The controller may receive information concerning the characteristics of the pressure pulses from a pressure sensor mounted proximate the bottom hole assembly, as well as information concerning the angular orientation of the rotor by means of an encoder. The controller may also receive instructions for controlling the pressure pulse characteristic from the surface by means of encoded pressure pulses transmitted to the pulser from the surface that are sensed by the pressure sensor and decoded by the controller.

摘要： A system for cooling electronic components in the downhole assembly of a drill string through which a drilling fluid flows. The cooling system includes a thermoelectric cooler that conducts heat from the electronic component to a first heat transfer surface of a thermal conductor. The heat received by the first heat transfer surface is transferred within the thermal conductor to a second heat transfer surface that then transfers the heat to a housing. The housing transfers the heat to the drilling fluid flowing over the housing. To ensure good conductive heat transfer between the electronic component, the thermoelectric cooler, the thermal conductor and the housing, and to absorb shock, vibration and differential thermal expansion, these components are supported on a spring mechanism that generates a force that biases the electronic component against the thermoelectric cooler, the thermoelectric cooler against the thermal conductor and the thermal conductor against the housing.

摘要： An apparatus and method for damping vibration, especially torsional vibration due to stick-slip, in a drill string, Sensors measure the instantaneous angular velocity of the drill string at one or more locations along the length of the drill string. One or more vibration damping modules are also spaced along the length of the drill string. When torsional vibration above a threshold is detected, the damping module imposes a reverse torque on the drill that dampens the torsional vibration. The reverse torque can be created by imparting a frictional resistance to the rotation of the drill string. The frictional resistance can be created externally, by extending friction pads from the damping module so that they contact the bore hole wall and drag along the bore hole as the drill string rotates, or internally by anchoring a housing mounted on the drill string to the wall of the bore hole and then imposing frictional resistance on a fluid, such as a magnetorheological fluid, flowing within the drill string.
