USING SOLENOID CHARACTERISTICS FOR PERFORMANCE DIAGNOSTICS ON ROTARY STEERABLE SYSTEMS

摘要

An extendable member diagnostic assembly determines performance of one or more components of a rotary steerable system. Based on the determined performance, an operation can be altered, such as a drilling operation. Performance may be based on measurements received from one or more sensors associated with components of the extendable member diagnostic assembly. For example, performance may be based on the time to transition a valve between states where the valve controls actuation of an extendable member, downhole temperature, downhole pressure or any other factors that affect performance of components that are used to perform the drilling operation. A controller receives the measurements from the one or more sensors and updates baseline parameters to determine an accurate performance. Using real time data to determine performance increases efficiency of an operation by eliminating unnecessary replacement of components and indicating that a downhole tool should be retrieved prior to failure.
