摘要： A power control device includes a communication device configured to be disposed in a borehole and configured to couple electrical power from a power source to a downhole component from a conductor disposed along a borehole string, a circuit breaker system including a first circuit breaker disposed at a connection between the conductor and the downhole component and configured to be closed to connect the downhole component to the conductor, and a controller configured to monitor at least one of a current level and a voltage level at the connection and at the conductor. The controller is configured to control the circuit breaker system and autonomously perform opening the first circuit breaker in response to detecting a deviation in the at least one of the current levels and voltage levels at the connection, to isolate the downhole component from the conductor and the power source.

摘要： Examples of high-temperature memory modules used in a well operation are disclosed. In one example implementation according to aspects of the present disclosure, a memory module may include: a control unit configured to receive data from a controller in the well operation and further configured to receive an operating temperature downhole in the well operation and to cause the control unit to initiate a shutdown of the memory module if the operating temperature is greater than a first threshold; and a memory controller configured to receive the data from the control unit and to commit the data to storage medium.
