A method for actuating a downhole tool including creating a magnetic pulse, coupling the magnetic pulse to a workpiece and moving the workpiece with the pulse, the workpiece achieving a minimum velocity of 200 meters per second.
摘要:
A method of managing data obtained in a borehole is provided. The method includes monitoring a characteristic with at least one sensor and obtaining raw data therefrom; indexing the raw data with the at least one sensor; recording the indexed data with the at least one sensor; forming a data packet with the at least one sensor, the data packet including at least a portion of the indexed data and index information; and transmitting the data packet in a predetermined segment of a communication protocol.
摘要:
The present disclosure relates to apparatuses and methods for terminating communication on a communication line between a carrier and at least one node located at a subsurface location. The apparatus may include a control member configured to initiate termination of communication in response to a controlled signal. The apparatus may also include a communication linkage configured to terminate the communication in a manner that cannot be remotely restored in response to the control member. The apparatus may also include a power source to maintain power to the communication linkage termination operation. The apparatus may be configured to use energy from the communication line to cause the communication linkage to terminate communication. The apparatus may be configured to use a communication linkage that is at least partially consumable. The method includes the use of the apparatus.

A method of determining the position of a valve includes, measuring pressure at a first location within a bore and measuring pressure at a second location within the bore wherein the first location and the second location are positioned on opposing longitudinal sides of the valve. The method further includes analyzing values from the measuring and attributing characteristics of the analyzing to specific valve positions.
摘要:
An compact instrumented downhole coupling that includes a carrier and a set of sensors and electronics that are installed within the carrier. The carrier is a tubular structure having couplings at each end and a bore extending through the carrier from the first end to the second end, forming a carrier wall between the bore and the exterior surface of the carrier. The bore and couplings are offset from a central axis of the carrier (the axis of the cylindrical outer surface of the carrier), resulting in a thicker portion of the carrier wall on one side of the carrier. Cavities are formed (e.g., by drilling holes) within the thicker portion of the carrier wall. One or more sensors and corresponding electronics are then positioned within the cavities, so that the carrier wall itself forms a housing for the sensors and electronics.
