摘要： A method for triggering an action of at least one downhole device on a downhole network integrated into a downhole tool string synchronized to an event comprises determining latency, sending a latency adjusted signal, and performing the action. The latency is determined between a control device and the at least one downhole device. The latency adjusted signal for triggering an action is sent to the downhole device. The action is performed downhole synchronized to the event. A preferred method for determining latency comprises the steps: a control device sends a first signal to the downhole device; after receiving the signal, the downhole device sends a response signal to the control device; and the control device analyzes the time from sending the signal to receiving the response signal.

摘要： A method and system for use in synchronizing at least two clocks in a downhole network are disclosed. The method comprises determining a total signal latency between a controlling processing element and at least one downhole processing element in a downhole network and sending a synchronizing time over the downhole network to the at least one downhole processing element adjusted for the signal latency. Electronic time stamps may be used to measure latency between processing elements. A system for electrically synchronizing at least two clocks connected to a downhole network comprises a controlling processing element connected to a synchronizing clock in communication over a downhole network with at least one downhole processing element comprising at least one downhole clock. Preferably, the downhole network is integrated into a downhole tool string.

摘要： A method for remotely managing downhole power consumption in a downhole network system is disclosed. The method comprises the steps of monitoring an activation state for each of a plurality of individually activatable electrically-powered modules in a downhole device and determining an optimal activation state for each module according to system demands. The activation state of each module may be selected from the group consisting of activated or deactivated. The method further comprises the step of transmitting a power state switching instruction from a top-hole processing element to a downhole power-consumption state controller over the downhole network. The method also includes the step of switching the selected electrically-powered modules according to the determined optimal activation states.
