Explanation of cementing plug

Cementing tools are classified into several categories,such as:seal ring,rubber ring,valer body,valer seat,Y-type high pressure three-way,pipeline clip,copper sleeve,copper gasket,copper ring,copperring,anti-return joint,high pressure sub,yuen.Today we are going to focus on cementing plugs.
1,the casing rubber plug

The casing plug is used for casing cementing on jack-up platforms and jacket jackets.The bottom plug(red)is used to isolate the cement slurry from the front fluid,preventing the forward cement slurry from being contaminated before the floating collar is released.The top plug(yellow)is used to separate the displacement fluid from the cement slurry to prevent the cement slurry from being contaminated by the displacement fluid.The top plug is also used to bump the cement slurry to indicate the completion of the cementing.

2.Liner rubber plug group

The liner rubber plug is connected to the collar at the lower end of the center pipe of the liner feeding tool.The drill pipe rubber plug is placed through the cement head of the liner pipe.After scraping the cement slurry in the drill pipe and compounding with the liner rubber plug,the liner pipe rubber plug is cut and released.The liner plug runs down to displace the cement slurry to the ball seat.

However,these cementing tools are not quite complete,there should be many specific models in the above classification,and there are a lot of different accessories for various wellheads.Customers can directly call our website for detailed consultation.
