Filed:

Feb 21, 2000

Appl. No.:

09/507610

Inventors:

Wallace R. Gardner - Houston TX
Vimal V. Shah - Houston TX
Donald Kyle - Plano TX

Assignee:

Halliburton Energy Services, Inc. - Dallas TX

International Classification:

G01V 300

US Classification:

3408554, 3408544, 367 82

Abstract:

A reliable downhole acoustic telemetry system with increased data rate is disclosed. In one embodiment, the telemetry system includes a receiver having an envelope-detection demodulator and a multipulse-block distance detector that compares a baseband envelope signal to stored waveforms and indicates for each symbol interval the multipulse block having the waveform closest to the baseband envelope signal. The receiver may also include a timing recovery module that models the baseband envelope signal for the detected multipulse blocks and determines a distance for early-sampling and late-sampling of the baseband envelope signal. The timing recovery module then provides a sampling clock that minimizes the average difference between the early- and late-sampling distances. The telemetry system may further include a transmitter having an encoder and a modulator. The encoder converts a data signal into a sequence of multipulse blocks having a settling interval between the blocks.

Abstract:

System, apparatus, and method of telemetering downhole sensor information to the surface while operations are performed in an oil or gas well using coiled tubing. Data are transmitted on coiled tubing as digital signals encoded in acoustic signals. In one implementation, a stripper packer through which coiled tubing is moved into a well is operated between at least a first state and a second state; and an acoustic communication device responds to operation of the stripper packer such that when the stripper packer is in the first state, the acoustic communication device is decoupled from acoustic communication with the coiled tubing, but when the stripper packer is in the second state, the acoustic communication device is coupled for acoustic communication with the coiled tubing.

International Classification:

H04H009/00
G01V003/00

US Classification:

367/082000, 340/853700, 340/853200

Abstract:

An acoustic telemetry system for use in a borehole achieves both bi-directional and multi-hop communications without need for a wireline. Each step in the communications link comprises a processor and transceiver, which communicate with adjacent transceivers to achieve self-optimization. During operation, if communications deteriorate, each pair of transceivers can re-initiate optimization and attempt to reset parameters to achieve improved communications. Similarly, the system can also re-calibrate periodically to assure that optimal conditions are maintained.

Abstract:

A communication system usable in a borehole in which a downhole modem wirelessly communicates with a surface modem using discrete multi-tone (“DMT”) modulation. The communication may be one-way (i.e., from downhole modem to surface modem, or vice versa) or two-way between the two modems.
