Pump-in Sub

Pump-in Sub 

The Pump-in Sub is normally positioned below the wireline BOP and above the wellhead. Its main function is to

allow well control by pumping fluid below a closed wireline BOP. It's mainly used for the pump truck by the fracture

lines or the drilling hose to pumping fluid to wash well or inject water into lubricator and add pressure to do pressure

self-inspection, or bleed the residual liquid in the lubricator when the wellhead valve has closed and the lubricator

has released the pressure etc.

The plug valve is used for injecting water and adding pressure or close wellhead after pumping fluid into the well,

thereby dismantle the drilling hose, also can used for bleeding the pressure liquid in the well or in the lubricator by

the drilling hose. the manometer used for observing the pressure in lubricator at any time. The pump-in sub is mainly

composed of tee body, union lower adapter, manometer, cock valve etc.
