Closed-loop drilling system using a high-speed communications network

摘要: A closed-loop downhole drilling system is disclosed that includes a high-speed communications network, comprising multiple nodes, integrated into string. The network supports data transmission rates far exceeding of mud pulse telemetry systems. Sensors, located at selected points along the string, are operably connected to nodes and transmit through corresponding conditions sensed downhole. control module receives sensor automatically adjusts uphole or downhole-drilling parameters in response thereto.
