摘要： Signal communications at a drilling system generally includes communicating upwards or downwards from the rig floor. For example, signal communications upwards may comprise the control of a cementing head operation (e.g., actuating cementing head). Signal communications downwards may comprise the activation of tools and their confirmation (e.g., hole opening tools, liner hangers, and packers). Actuation may be performed via umbilicals, for example, via pressure spikes or the dropping of balls, darts, or radio-frequency identification (RFID) tags. However, issues may arise wherein, for example, a ball may not properly land to close a circulation valve. As another example, a cementing head could be over 100 feet above the rig floor, which may make it difficult for signal communications via an umbilical. Accordingly, what is needed are techniques and apparatus for activation of tools and their confirmation by a remote communication system.
摘要翻译：在钻井系统中的信号通信通常包括从钻井平台向上或向下传播。例如，向上的信号通信可以包括对固井头操作的控制（例如，致动固井头）。向下的信号通信可以包括启动工具及其确认（例如，开孔工具，衬管悬挂器和封隔器）。致动可以通过脐带，例如通过压力尖峰或掉落球，飞镖或射频识别（RFID）标签来执行。然而，可能会出现这样的问题，例如，球可能没有适当地着陆以关闭循环阀。作为另一个例子，固井头可以在钻台上方超过100英尺，这可能使得通过脐带的信号通信变得困难。因此，需要的是用于激活工具的技术和装置及其由远程通信系统的确认。

摘要： A drill bit made according to one embodiment includes a bit body and at least one preloaded sensor in the bit body. In one aspect, the sensor may include a sensor element on a sensor body having a first end and a second end and wherein the sensor is preloaded after placing the sensor body in the bit body. In another aspect, the sensor may be preloaded outside the bit body and then placed in the bit body in a manner that enables the sensor to retain the preloading.

摘要： A drill bit for drilling subterranean formations includes a bit body bearing at least one gage pad and a shank extending from the bit body. An annular chamber is formed within the shank. A data evaluation module is disposed in the annular chamber and includes a processor, a memory, and a communication port. The data evaluation module estimates a gage pad wear by periodically sampling a tangential accelerometer and a radial accelerometer disposed in the drill bit. A history of the tangential acceleration and the radial acceleration is analyzed to determine a revolution rate, gage-slipping periods, and gage-cutting periods. A change in a gage-pad- wear state is estimated responsive to an analysis of the revolution rate, the at least one gage-cutting period and the at least one gage-slipping period. The determination of the gage-pad-wear state may also include analyzing a formation hardness.
