摘要： A system is disclosed for optimizing mud-pulse communications in a wellbore. The system may include a mud pulser positionable in the wellbore and a surface detection system. The mud pulser can transmit a sequence of waveforms having various data rates to the surface detection system for synchronizing the mud pulser with the surface detection system. The surface detection system may receive the sequence of waveforms from the mud pulser and may determine one or more waveforms of the sequence of waveforms having amplitudes exceeding a predefined threshold. The surface detection system may then determine which of the one or more waveforms has a fastest data rate, and select the fastest data rate for use in subsequent communications with the mud pulser.

摘要： This disclosure presents systems to enable downhole bi-directional communications using a long length of electrical cable located within or partially within the internal diameter of a set of lower pipe segments and communicatively coupled to one or more upper pipe segments that utilize pipe cable attached to the outside diameter of each of the upper pipe segments. The long length of electrical cable and the one or more pipe cables from the upper pipe segments allow for communication coupling between downhole tools and surface equipment and surface computing systems. In some aspects, the pipe cable attached to the upper pipe segments can be protected from wear using clamps, collars, cages, and other protectors. In some aspects, an electrical signal generator and modulator can be located downhole proximate the downhole tools, uphole proximate one of the upper pipe segments, or proximate the surface equipment.

摘要： The resonant frequency of an example transducer can be adjusted by changing the effective mass of a backing mass using a tuning module. The tuning module includes a electrical source, a switch, and an electromagnetic coil connected in series as an electrical circuit. The electromagnetic coil is mechanically attached to the backing mass, and is disposed within a reservoir of a magneto-rheological fluid enclosed within a casing. When the switch is closed, the electrical source applies a voltage and current to the electromagnetic coil, and induces a localized magnetic field within the magneto-rheological fluid. In response to this localized magnetic field, the magneto-rheological fluid increases in viscosity, assumes properties comparable to a viscoelastic solid, and become affixed to the electromagnetic coil. As the electromagnetic coil is mechanically attached to the backing mass, the solidified magneto-rheological fluid increases the effective mass of the backing mass. As a result, the resonant frequency of the transducer is altered.
