Downhole tool system

摘要

Configuring a downhole tool string where a control signal leaves only the first of the tools 100 in communication with a control unit 12involves the control unit 12 sending an identification query to the first tool 100; where the first tool 100 responds to the query and the control unit 12 associates the signal with a first address which is then transmitted to the first too1 100; the control unit 12 then sends a close signal to the first tool 100 and repeats said step with each of the tools 200, 300.
