摘要：
Pump-off detection, and actions to avert a pump-off event from occurring, are described that may be implemented in a wireline control system while performing a pump-down operation to position a downhole tool within a wellbore. As part of the pump-down operation, the downhole tool is attached to a wireline coupling the tool to a wireline control device located at the surface above the wellbore.
