摘要： A method for reducing noise in downhole fluid communications includes processing first and second received signals in combination with a strobe signal from an active pump to obtain pump signatures at first and second spaced measurement locations. The pump signatures are used to compute a transfer function of the fluid channel between the two measurement locations. The transfer function may then be used to estimate the telemetry signal traveling in the uphole direction.

摘要： An orientation measurement system is deployed in a wellbore drilling system having one or more reservoir imaging and characterization tools, directional tools, and/or other known BHA tools in a rotating section. The orientation measurement system includes a processor receiving signals from a rotary position sensor measuring an angular position of the rotating section relative to the non-rotating section and receiving signals from an orientation sensor determining the orientation of the non-rotating section relative to a reference frame such as highside. The processor uses the first and second signals to determine a tool face of the rotating member relative to the highside and periodically and/or continuously transmits the determined tool face along the BHA via a suitable communication link. The determined tool face is used by the BHA tools to synchronize measurements with highside and/or to determine azimuth.

摘要： A system for transmitting information in a well comprises a tubular string disposed in the well and having a drilling fluid flowing therethrough. A pulser is disposed in the tubular string and transmits a pulse synchronization marker comprising a chirp signal. A surface controller, acting under programmed instructions, detects the chirp signal adjusts a signal decoding technique based on the detected chirp signal.
