Oilfield Drillable Cement Tool Rubber Material Cement Plug

The function of the rubber stopper is: when all the cement slurry is poured, press the rubber stopper, which goes down against the cement slurry to scrape the cement slurry adhered to the inner wall of the casing and prevent the displacement of drilling fluid and cement slurry. Mixing to avoid the contamination of the cement slurry at the tail and ensure the quality of cement cementation at the bottom. When it reaches the spoiler, the pressure is displayed, and the cementing operation ends.

The function of the lower rubber stopper is: before the cement slurry is injected, the lower rubber stopper is released to separate the cement slurry and the pre-fluid. Reduce the pollution of the cement slurry injected into 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 rubber stopper reaches the baffle, a small pressure can be applied to crush the rubber diaphragm on the rubber stopper, so that the cement slurry flows through the rubber stopper, and is displaced to the casing and the casing through accessories such as swirl shorting. in the annular space between the well walls.
