Soft-wire conductor wellbore telemetry system and method |
摘要 |
A resilient conductor having an outer flexible insulating coating and an inner flexible conducting core is employed in a drill string to maintain an electric circuit between a subsurface and surface location. The conductor is inserted in the drill string in a generally free-hanging, random fashion to store excess length of conductor which is utilized as the drill string is lengthened. The stored conductor can be maintained in the drill string in a generally untangled state due to its kink-resistant mechanical and physical properties. Moreover, the frictional drag of the flowing drilling fluid tends to straighten and disentangle the conductor.
