    • Autonomous control of a wellbore tool is provided by programming a memory module of a processor with a database having data relating to a selected parameter of interest; conveying a sensor and the processor along the wellbore; and activating the wellbore tool if the processor determines that a measurement provided by the sensor correlates with the database data. The processor may correlate the sensor measurements with a predetermined pattern associated with the data, a preset value, and/or a preset range of values. Well tool activation may occur when the processor finds: a substantial match between a predetermined pattern and at least one measured value; a present value and at least one measured value, and/or a preset range of values and at least one measured range of values. Also, activating the well tool may occur only if a measurement from a second sensor meets a preset criteria.

    • A method for determining depth in a wellbore uses inertial navigation in conjunction with a database having one or more measured parameters correlated with depth. The measured parameter may be the lengths of stands forming a drill string, prior survey data relating to a naturally occurring feature such as formation lithology, or data relating to a human made feature such as collars in a casing string. The downhole processor may use accelerometer measurements to calculate a measured depth of a BHA and access the database to retrieve a predicted depth that corresponds with one or more sensor measurements (e.g., motion indicating the addition of a stand to a drill string). Thereafter, if the downhole processor determines that the predicted depth is in agreement with the calculated depth, the processor stores the predicted depth and/or associates the predicted depth with directional surveys taken along the wellbore.
    • 用于确定井眼深度的方法使用惯性导航与具有与深度相关的一个或多个测量参数的数据库结合使用。 测量参数可以是形成钻柱的立场的长度,与诸如地层岩性的天然存在特征相关的先前测量数据,或与人造特征(例如套管柱中的套环)有关的数据。 井下处理器可以使用加速度计测量来计算BHA的测量深度并访问数据库以检索与一个或多个传感器测量值相对应的预测深度(例如,指示向钻柱添加支架的运动)。 此后,如果井下处理器确定预测深度与计算出的深度一致,则处理器存储预测深度和/或将预测深度与沿着井眼进行的定向勘测相关联。
