    摘要: Apparatus and method for transmitting data in a borehole (10) between a downhole installation including one or more tools (20) (for example downhole testing tools) and a surface installation (62), wherein the downhole installation is connected to the surface installation by means of a tubular conduit (such as a drill string or production tubing 14)). The apparatus comprises: an acoustic modem (26) associated with each tool, the modem acting to convert tool signals such as electrical tool signals into acoustic signals; and a hub (90) forming part of the downhole installation to which the tools and tubular conduit are connected and comprising an acoustic receiver (74) and an electromagnetic transmitter (80). The acoustic modems operate to generate acoustic signals in the downhole installation representative of the tool signals, the acoustic signals passing along the downhole installation to be received at the acoustic receiver of the hub, the received acoustic signals being used to operate the electromagnetic transmitter to transmit electromagnetic signals to the surface for reception at the surface installation.

    摘要: A downhole communication system and method is presented for communicating between a downhole location within a wellbore and a surface location. The system preferably comprises a first and second telemetry module, a downhole tool, and an interface electrically connecting the downhole tool to the first and second telemetry modules. The first telemetry module is connected to a string and positioned downhole within the wellbore, and configured to receive communication signals via acoustic propagation or low frequency electromagnetic transmission. The second telemetry module is connected to the string and positioned downhole within the wellbore, and configured to receive communication signals via fluid pressure pulse commands. The downhole tool is operatively connected to the string. And the interface is adapted to selectively relay digital communication signals between the downhole tool and at least one of the first and second telemetry modules.

The data retrieval device is provided with a housing adapted to be positioned inside the string; a communication device supported by the housing; a connection port positioned on the housing and adapted to be connected to a line; and an electronic module supported by the housing. The electronic module is in communication with the communication device and is adapted to store and use at least an identification parameter of the first telemetry module to intercept a signal transmission addressed to the first telemetry module from the second telemetry module (18) via the communication device.
