摘要： An apparatus and method for monitoring and reporting downhole bit (108) failure. Sensors (106) are located on a sub assembly (104) (which is separate from the drill bit (108) itself but located above it on the drill string (102)). Data from the sensors (106) are collected in blocks, then analyzed in the frequency domain. The frequency domain is divided into multiple bands, and the signal power in each band is compared to that of another band to produce a ratio of powers. When a bit (108) is operating at normal condition, most of the spectral energy of the bit vibration is found in the lowest frequency band. As a bearing starts to fail, it produces a greater level of vibration in the higher frequency bands. This change in ratios is used to determine probable bit (108) failure.
摘要翻译：一种用于监测和报告井下钻头（108）故障的装置和方法。传感器（106）位于子组件（104）上（与钻头（108）本身分离，但位于钻柱（102）上）。来自传感器（106）的数据以块为单位收集，然后在频域中进行分析。将频域划分为多个频带，并将每个频带的信号功率与另一个频带的信号功率进行比较以产生功率比。当位（108）在正常条件下工作时，位振动的大部分频谱能量被发现在最低频带。随着轴承开始失效，它在较高频段产生较大的振动水平。这种比率变化用于确定可能的位（108）故障。

摘要： A real-time line management system and associated methods. Aline management system for use in conjunction with an operation in a subterranean well includes a line installed in the well during the operation, and a computing device which indicates a used life of the line during the operation. A method of managing a line used in an operation in a subterranean well includes the steps of: installing the line in the well during the operation; and determining a used life of the line while the line is installed in the well. A method of managing a line used in multiple operations in one or more subterranean wells includes the steps of: estimating conditions which will be experienced by the line during a future operation; and predicting before the future operation what a used life of the line will be after the line is used in the future operation.

摘要： An apparatus and accompanying method for monitoring and reporting downhole bit failure. Individual sensors (106) are placed on a sub (104) which is separate from the drill bit (108) itself, and are powered by a vibration driven power system. The sensor readings are used to compute values which represent the ratios of sensor readings on one sensor (106) in relation to the readings on one or more other sensors (106). This creates a self-calibrating sensor system that accounts for changes in downhole conditions which might cause sensor readings to fluctuate, but which do not indicate failure.

摘要： A drill string is equipped with a downhole assembly having an instrumented sub and a drill bit. The instrumented sub has a power source that requires no electrical chemical batter. A mass-spring system is used, which during drilling causes a magnet to oscillate past a coil. This induces current which is used to power downhole instruments. .

摘要： An apparatus and method for monitoring and reporting downhole bit failure. Sensors (3302) are located on a sub assembly (104) (which is removable from the drill bit (108) and send data to neural net or other adaptive filter (3306). The neutral net (3306) uses past sensor readings to predict future sensor readings. The value predicted for the sensors (3302) is substracted from the actual value to produce a prediction error. Increases in prediction error are used to indicate bit failure. The results of this are transmitted to the operator by varying the pressure in the drilling mud flow.

摘要： A method and apparatus is described for signalling the surface operator about downhole conditions. Sensors (4716) located downhole collect data while drilling and the data is processed to determine bit failure, for example. When the sensor data indicates a failure, the pressure of drilling mud is varied using a valve (4710) on the downhole unit (4706), and this pressure variance is indicated by a pressure gauge visible to the operator. This pressure change tells the operator a failure has been indicated.
