摘要： A downhole crystal-based clock that is substantially insensitive to the factors that may cause frequency deviation as a result of downhole temperature. The clock may include a plurality of crystals, where a first crystal may be more stable, with respect to temperature, than a second crystal. The crystals may be thermally coupled together so that they may have substantially the same temperature. An error detector may monitor the differences between the frequencies associated with each crystal and provide this information to a storage device. This information may be determined prior to deploying the clock downhole. When deployed downhole, the signal from the error detector may be interpreted in light of the information in the storage device to provide a temperature measurement of the two crystals. The downhole temperature measurement then may be used to reduce frequency deviations in the downhole clock that may result from downhole temperatures.
摘要翻译：基于井下晶体的时钟，对由于井下温度可能引起频率偏差的因素基本上不敏感。时钟可以包括多个晶体，其中第一晶体相对于温度可以比第二晶体更稳定。晶体可以热耦合在一起，使得它们可以具有基本上相同的温度。误差检测器可以监视与每个晶体相关联的频率之间的差异，并将该信息提供给存储设备。该信息可以在井下部署时钟之前确定。当部署在井下时，来自误差检测器的信号可以根据存储装置中的信息来解释，以提供两个晶体的温度测量。然后可以使用井下温度测量来减少可能由井下温度引起的井下时钟的频率偏差。

摘要： Various electromagnetic LWD telemetry systems are disclosed having a wireless repeater positioned on or near the seabed. The wireless repeater receives and demodulates electromagnetic uplink signals and retransmits the uplink signals from the seabed as electromagnetic or acoustic signals. A receiver on the drilling platform or suspended from the water's surface receives the uplink signal and forwards it to a facility for processing and storage. In some embodiments, the wireless repeater takes the form of a sub threaded inline with the drill string with an electromagnetic signal sensor positioned inside the drill string. In other embodiments, the wireless repeater takes the form of a unit that rests on the seabed with electromagnetic signal sensors inserted into the sea bottom.

摘要： A drill pipe forms an acoustic transmission channel for data to be transmitted from a downhole transceiver to a surface transceiver. By positioning a first low frequency acoustic attenuator between a drill bit and the downhole transceiver, acoustic noise generated by the drill bit is attenuated. Similarly, by positioning the surface transceiver between the top of the drill pipe and a second low frequency acoustic attenuator, acoustic noise generated by surface equipment is attenuated. In this manner, the first and second low frequency acoustic attenuators serve as terminators for the acoustic transmission channel. Finally, by combining a third low frequency acoustic attenuator positioned between first and second sections of the drill pipe with first and second acoustic transceivers acoustically isolated from one another by the third low frequency acoustic attenuator and non-acoustically coupled to one another for bi-directional exchanges of signals, an acoustic repeater is provided for the transmission channel.

摘要： An acoustic attenuator includes a housing having an inner side surface which defines an interior chamber and at least one dampening member both physically and acoustically coupled to the housing and projecting into the interior chamber. Acoustic energy propagating within the housing is deflected into the dampening members for acoustically dispersal within the interior chamber. In various aspects thereof, the dampening members may include one or a group of two or more generally cylindrical sleeves having one end both physically and acoustically coupled to the housing and a second end projecting into the interior chamber. Preferably, when a group of two or more cylindrical sleeves are employed, the sleeves are nested within one another. The dampening members may further include a second, oppositely disposed, group of two or more acoustic attenuators nested within one another and interdigitated with the first group of cylindrical sleeves.
