计量柜和精计量柜描述引用:
A stripping tank is a small trip tank.
It purpose is to count the displaced fluid from the well when stripping in the hole - It is the size of 5 or 10 bbl max due to the fact that it has to be able to count volume very accurately- (trip tank is usually 40 bbl)
Procedure while stripping in hole
BOP Annular closed, driller lowers 1 or 2 stands of pipe into the hole through the closed annular, the pipe attempts to displace the equal volume of fluid , due to annular closed it cannot so well bore pressure increases. After a pre-calculated amount of pipe and pressure increase it is required to bleed off through the choke line an exact amount of fluid. So you line up the choke manifold to the strip tank where you can count bleed off very accurately |
