The cementing plug is used to isolate the cement slurry, clean the casing wall, and prevent the cement slurry from being polluted. After the rubber plug is pressed on the floating hoop, it can accurately indicate the replacement position of the cement slurry and the sealing performance of the casing.

Buy Anti-rotation cementing plug

The upper rubber stopper and the lower rubber stopper are generally used as a set. The upper rubber plug is separated from the upper grout and mud to prevent contamination of the grout while displacing the grout into the annulus.

Before cementing, place the lower rubber plug, and use the pump to scrape the well wall to separate the lower cement slurry from the mud to prevent the cement slurry from being polluted. After pressing, since the lower rubber stopper is hollow, keep the pressure of 2-4MPa to rupture the rubber film, provide a channel for the cement slurry, and establish a circulation. Then, pour the cement, insert the rubber plug, pump, touch the pressure, and the cementing is over.
