Patent CA-2387616-A1 (CA)
Inventor: KRUEGER VOLKER
IPC: E21B47/12
Filed: 2000-10-13
Abstract: In general, the present invention provides a contactless apparatus for power and data transfer over a gap between rotating and non-rotating members of downhole oilfield tools. The gap usually contains a fluid, such as drilling fluid, or oil for operating hydraulic devices in the downhole tool. The downhole tool in one embodiment is a drilling assembly wherein a drive shaft (112) is rotated by a downhole motor to rotate the drill bit attached to the bottom end of the drive shaft. A substantially non-rotating sleeve (120) around the drive shaft includes at least one electrically-operated device. An electric power and data transfer device (135) transfers electric power and data between the rotating and non-rotating members. An electronic control circuit associated with the rotating member controls the transfer of power and data from the rotating member to the non-rotating member. An electrical control circuit carried by the non-rotating member controls the transfer of data from sensors and devices carried by the non-rotating member to the rotating member.

Abstract: A communication line is installed in a network by automating a design phase and a configuration phase for the service and by automating the failure recovery in either of the phases. In the design phase, an optimal route for the communication line is found, and the network components are provisioned and assigned. If the assigned network components are not available or can not be validated, the components causing the failure are marked, and the design phase is retried without the marked components. After the design phase, the configuration phase begins. The circuit design is tested against actual network components. If the test is passed, the actual network is configured according to the circuit design and the circuit is activated. If there is a network component failure during the configuration phase, the good route elements in the design are released while the failed network components are marked.  The design phase is retried.
