摘要： A hybrid telemetry system includes a plurality of telemetry networks configured to communicate a modulated signal representing digital data along adjoining sections of a pipe string. The plurality of telemetry networks may each be optimized or particularly suitable for the configuration of the pipe string, the well, and/or the environment of the well occurring in each of the adjoining sections. Some of the plurality of telemetry networks may overlap to provide redundancy of the communication of the digital data.

摘要： A combined telemetry system that can be used while drilling a wellbore consists of a multi-hop telemetry method and a single-hop telemetry method combined in parallel. The multi-hop and single-hop methods can be operated in parallel, for example, so that each telemetry method caries data concurrently from the Measuring-While-Drilling tool located in the Bottom-Hole-Assembly. The multi-hop and single-hop methods can also be operated in series, for example, so that data from the Measuring-While-Drilling tool located in the Bottom-Hole-Assembly are first carried with the single-hop telemetry method and then transferred to the multi-hop telemetry method at one or more node(s) close to the surface. Preferably, the multi-hop telemetry method can also carry data from along-string sensors. Another combined telemetry system that can be used while drilling a wellbore consists of two single-hop telemetry methods combined in parallel.

摘要： A downhole acoustic transmitter has a piezoelectric transducer, an enclosure in which the piezoelectric transducer is housed, a transducer preload means which applies a selected compressive force against the transducer such that a mechanical preload is applied to the 5 transducer, and an acoustic tuning element which has a first end coupled to the transducer preload means or the transducer, and an open second end. The acoustic tuning element is not coupled to anything but the transducer preload means or transducer, so the transducer preload means effectively has a second open end and thus can maintain the same preload compressive force on the transducer even when the transmitter is subjected to tension and 10 compressive forces during operation.
