Method and devices for terminating communication between a node and a carrier

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.

1. A method of controlling a communication along a carrier, comprising:
using the carrier to communicate electrical energy; positioning a communication linkage and at least one node at a subsurface location, the at least one node in the communication with the carrier via the communication linkage, the at least one node comprising: a control member to initiate an energy flow to the communication linkage, and a second control member to form a circuit that allows the energy flow to have a sufficient electrical energy flow to destroy at least a part of the communication linkage, wherein the at least the part of the communication linkage includes a consumable element, and wherein applying the sufficient electrical energy flow from the carrier transforms the consumable element into a disintegrated state to cause to non-reversibly terminating the communication between the carrier and the at least one node; activating the control member and the second control member using a controlled signal: destroying the at least the part of the communication linkage upon receiving the controlled signal; and using the controlled signal to said non-reversibly terminating the communication between the carrier and the at least one node.
