Pump Deployment Via Cable |
| 摘要 |
A method can include providing a pump connected to a power cable with a smooth surface; providing a stuffing box with a valve configured to form a seal with the smooth surface of the power cable in a closed state and to form a passage for the pump as connected to the power cable in an open state; providing a lubricator; providing a blow-out protector with a valve configured to form a seal with the smooth surface of the power cable in a closed state and to form a passage for the pump as connected to the power cable in an open state; and controlling the states of the valves while lowering the pump via the power cable through the stuffing box, the lubricator, and the blow-out protector to position the pump into a bore of a well. Various other apparatuses, systems, methods, etc., are also disclosed. |
