DOWNHOLE SWITCH ASSEMBLIES AND METHODS |
| 摘要 |
A switch assembly includes one or more solid state semiconductor switches configured to be disposed within a downhole pipe assembly. The one or more switches are configured to operate in a closed state to conduct electric current supplied by a power source disposed above a surface to pumps disposed beneath the surface to cause the pumps to extract a resource from beneath the surface via the pipe assembly. The one or more switches also are configured to operate in an open state to stop conducting the electric current from the power source to the pumps. |
