The function of the rubber plug is: when all the cement slurry is injected, the rubber plug is pressed, and it goes down against the cement slurry to scrape off the cement slurry adhering to the inner wall of the casing and prevent the drilling fluid and cement slurry from being displaced. Mixing to avoid contamination of the tail cement slurry and ensure the quality of cement bonding at the bottom. When it reaches the baffle, it will show bumping, and the cementing operation will be finished.
The function of the lower rubber plug is: before the grout is injected, the lower rubber plug is released to separate the grout from the front fluid. Reduce the pollution of the grout injected in the casing. At the same time, wipe off the drilling fluid adhering to the inner wall of the casing and push it to the front of the rubber plug. When the lower rubber plug reaches the spoiler, a small pressure can be applied to break the rubber diaphragm on the upper part of the rubber plug, so that the cement slurry flows through the rubber plug, and is driven to the casing and the in the annular space between the well walls.
