摘要： A method for performing diagnostics on a wired drill pipe telemetry system of a downhole drilling system is provided. The method includes passing a signal through a plurality of drill pipe in the wired drill pipe (WDP) telemetry system, receiving the signal from the WDP telemetry system, measuring parameters of the received signal and comparing characteristics of the received signal parameters against a known reference to identify variations therein whereby a fault in the wired drill pipe telemetry system is identified. The signal, in the form of a waveform or a pulse, is passed through the WDP telemetry system. The impedance and/or time delay of the received signal is measured. By analyzing variations, such as resonance and/or reflections in the signal, the existence and/or location of a fault in the WDP telemetry system may be determined.

摘要： A cabled communication link for a drill string includes spaced apart adapter subs within the drill string and a cable connecting the adapter subs for communication of a signal therebetween. The cabled communication link may be drill pipe joints are interconnected within the drill string between adapter subs to form a piped communication link, whereby the cabled communication link establishes a pathway to the piped communication link for transmitting a signal through the drill string. The cabled communication link may also be in a non-wired section of the drill string is disposed between adapter subs, whereby the cabled communication link establishes a pathway for transmitting a signal through the non-wired section of the drill string. Inductive couplings are preferably used for communication across the adapter subs and wired drill pipe joints. Another aspect of the cabled communication employs wireless transceivers at or near the surface of the wellbore.

摘要： An expandable tubular sleeve having utility for lining a downhole tubular member includes a tubular body having a portion that is predisposed to initiate expansion thereof under the application of internal fluid pressure. The predisposed portion of the body may be a plastically-deformed portion formed, e.g., by application of mechanical force to a wall of the body. The predisposed portion of the body may be defined by a portion of the body having reduced wall thickness. The reduced wall thickness may be achieved, e.g., by reinforcing the wall thickness everywhere except the predisposed portion. The predisposed portion of the body may be formed by modifying the material properties of the body, e.g., by localized heat treatment. The sleeve and related apparatuses and methods are useful for securing and protecting a cable having one or more insulated conductive wires for transmission of signals between locations downhole and at the surface.
