Cementing plug

1. Casing rubber plug
Casing plugs are mainly used for casing cementing on jack-up platforms and jackets. Bottom plugs (red) are used to isolate cement slurry and preflush to prevent the forward cement slurry from being polluted before exiting the casing hoop. ;The top plug (yellow) is used to separate the displacement fluid from the cement slurry to prevent the subsequent cement slurry from being polluted by the displacement fluid. At the same time, the top plug is also used to bump pressure to indicate the end of the cementing slurry replacement.
2. Tail pipe rubber plug group
The liner plug is connected to the collar at the lower end of the center pipe of the liner feeding tool, and the drill pipe plug is put in through the cement head of the liner pipe, and the cement slurry in the drill pipe is scraped off and compounded with the liner plug, then sheared Release the tailpipe rubber plug. The tailpipe rubber plug descends to displace the cement slurry to the ball seat and then bumps against it.
