Subsurface Flow Control Systems
ХХХ lock mandrel system is a drive-down, jar-up-to-set, no-go-type system designed specifically for surface-controlled
subsurface safety valve (SCSSV) applications. This system consists of a ХХХ lock mandrel, running tool, and unlocking tool.
The design features a locking sleeve that moves upward in the direction of flow to establish a locked safety valve. This locking allows unlimited drivedown action without the possibility of presetting the lock while it travels downhole.
Заранее спасибо.

Note from asker:
| Если Вы даете перевод из Мультитрана, объясните, пожалуйста, как Вы представляете себе смысл приведенных фраз, в частности, "unlimited drivedown action". Мне вот кажется, что речь идет о каком-то усилии, направленном вниз по скважине, а не о уменьшении частоты. |
