摘要： A method and apparatus for providing a local response to a local condition in an oil well are disclosed. A sensor is provided to detect a local condition in a drill string. A controllable element is provided to modulate energy in the drill string. A controller is coupled to the sensor and to the controllable element. The controller receives a signal from the sensor, the signal indicating the presence of said local condition, processes the signal to determine a local energy modulation in the drill string to modify said local condition, and sends a signal to the controllable element to cause the determined local energy modulation.

摘要： A telemetry system, method and computer-readable recording medium are provided, the method including inducing a first pressure pulse in drilling fluid, which first pressure pulse has a leading pressure transition and a trailing pressure transition. Pressure variations are read at three or more locations, and the resulting pressure signals are used to determine a time between the leading and trailing pressure transitions.

摘要： Methods and apparatuses for drilling a borehole are disclosed. An electric motor electrically and mechanically coupled to a wired drill pipe is provided. The electric motor couples to a shaft that rotates when power is supplied to the electric motor. The shaft is couplable to a drill bit. The wired drill pipe transfers electricity to the electric motor from the surface. Operation of the electric motor rotates the shaft. The drill bit wears away earth to form the borehole in the earth.
