摘要： A method and apparatus for estimating a time to failure of an electronic component used in a downhole environment is disclosed. A stress is applied to the electronic component to cause failure of a plurality of prognostic sensors associated with the electronic component, wherein the stress level at which a prognostic sensor fails is indicative of a stress level at which the electronic component fails. Failure times are obtained due to the applied stress for the plurality of prognostic sensors. A trend is determined from the obtained failure times of the prognostic sensors. The time of failure of the electronic component is estimated from the determined trend.

摘要： A method, apparatus and computer-readable medium for determining a lifespan of an electronic component in a downhole environment is disclosed. A first wear-out model is created that is related to a selected electronic component. A physical condition of the selected electronic component is examined at a selected examination time. The physical condition is generally due to the downhole environment in which the electronic component is disposed. A second wear-out model for the selected electronic component is created from the first wear-out model and the examined physical condition of the selected electronic component.

摘要： A method for two-way communication for controlling production from a formation having at least one producing well and a plurality of producing zones. In one embodiment, the method comprises installing a flow control device with a controller proximate each of the producing zones, where each controller has a predetermined communication address, and each controller is adapted to act as a repeater on command from a surface controller; connecting each controller to a transmission bus where the transmission bus is connected to the surface controller; transmitting a command message from the surface controller to a predetermined downhole controller, where the command message determines a predetermined path along the transmission bus according to a predetermined protocol; receiving the command message by the predetermined controller; and executing the command message to control the flow control device. Transmitting a response message back along the predetermined path.

摘要： An apparatus and method for detecting the location of subsurface markers in a formation proximate to a borehole. The apparatus includes marker detectors in a housing having at least two housing sections attached in an initial orientation. The distance between the detectors is measured under controlled conditions with a calibration bar. The initial attached orientation between the housing sections is identified with a calibrator, and deviations from the initial attached orientation are identified by the calibrator after the housing sections are detached and reattached. The calibrator permits well site corrections to be made to the housing sections without recalibration. Gauges permit corrections for temperature and pressure fluctuations, and the corrected distances between the housing detectors is computed. Detectors in the housing generate signals when each detector is proximate to a marker in the formation, and such signals can be processed to identify the elevation of a marker in the borehole, or the distance between markers in the borehole, to determine formation compaction or settlement. In an apparatus having two detectors separated by a spacer, flexible retainers can be positioned between each detector and the spacer to permit thermal expansion or contraction of the detectors relative to the spacer.
摘要翻译：一种用于检测靠近钻孔的地层中地下标记的位置的装置和方法。该装置包括在壳体中的标记检测器，其具有以初始取向附接的至少两个壳体部分。检测器之间的距离在受控条件下用校准条进行测量。在壳体部分之间的初始附接取向由校准器识别，并且在拆卸和重新连接壳体部分之后，通过校准器识别与初始附接取向的偏差。校准器允许在不重新校准的情况下对外壳部分进行良好的现场校正。仪表允许校正温度和压力波动，并且计算外壳检测器之间的校正距离。当每个检测器接近地层中的标记物时，壳体中的探测器产生信号，并且可以处理这些信号以识别井眼中的标记物的高度或井眼中的标记之间的距离，以确定地层压实或沉降。在具有由隔离物隔开的两个检测器的设备中，柔性保持器可以位于每个检测器和间隔件之间，以允许检测器相对于间隔件的热膨胀或收缩。
