摘要： In conjunction with a communication network, for example, a downhole wireless network for transmission of data along a tubular body, disclosed herein are: (1) a variety of hardware interfacing methods with sensors and downhole tools; (2) sensing concepts that are enabled by the unique interfaces; (3) physical implementation of the integrated sensor/communication node structures; (4) related software communication protocols. The interfaces may support both data communication and power transfer.

摘要： A method of communication using a wireless network is disclosed. A wireless transmission of a signal is received at a first node. The signal has a frequency signature. The frequency signature of the received signal is compared with a frequency signature of a previously received signal from a second node. If it is determined that the frequency signature of the received signal and the frequency signature of the previously received signal are within a predetermined range of similarity, the received signal and the previously received signal are accepted as having been transmitted by the second node.

摘要： A hybrid electro-acoustic system for extending battery life of a downhole wireless telemetry system. The system includes a plurality of battery-powered intermediate communications nodes spaced along a downhole tubular body and attached to a wall of the tubular body, each of the battery-powered intermediate communications nodes configured to alternate between a sleep mode and an active mode and comprising: a power source comprising one or more batteries positioned within a housing; an electro-acoustic transducer and a transceiver, or a separate transmitter and receiver, positioned within the housing; and a topside communications node comprising: a transmitter and a power supply, the topside communications node structured and arranged to send an acoustic signal to one or more of the battery-powered intermediate communications nodes to place same in the active mode; wherein the power supply of the topside communications node is sufficient to enable communications directly with the intermediate communications node most remote from the surface and greater than the battery power provided to each of the intermediate communications nodes.

摘要： Methods of acoustically communicating and wells that utilize the methods are disclosed herein. The methods generally utilize an acoustic wireless network including a plurality of nodes spaced-apart along a length of a tone transmission medium. In some embodiments, the methods include methods of communicating when the acoustic wireless network is spectrum-constrained.
