There are many kinds of cementing tools, such as: sealing ring, rubber ring, valve body, valve seat, Y-type high-pressure tee, pipeline clamp, copper sleeve, copper pad, copper ring, copper ring, anti-return joint, High pressure pup joints, unions. The anti-rotation cementing plug company mainly explains the cementing tool - rubber plug today.

1. Casing rubber stopper

The casing rubber plug is mainly used for casing cementing on the jack-up platform and the jacket. The bottom plug (red) is used to isolate the cement slurry and the pre-fluid to prevent the forward cement slurry from being polluted before the casing floating 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 touch the pressure to indicate the end of cementing and replacing the slurry.

2. Tail pipe rubber plug group

The tail pipe rubber plug is connected to the coupling at the lower end of the center pipe of the tail pipe feeding tool. The drill pipe rubber plug is put through the tail pipe cement head, scraped off the cement slurry in the drill pipe and compounded with the tail pipe rubber plug, and then sheared. Release the tailpipe rubber stopper. The rubber plug of the tail pipe goes down to replace the cement slurry until it touches the ball seat.
