Cementing Plug
Production description of OIl drilling rig equipment tools Cementing plugs
Generally, Top plug and bottom plug are matched to use. Before cementing, put into bottom plug firstly, scrape and clean the wall of hole by pump. After pump plug, increase the pressure to 2~4 MPa,hold and broken the rubber film, circulation is established.
And then,start to inject the cement, put into top plug, pumping, increase the pressure, finished cementing. The Top Rubber plug has a core of epoxy coated sand compressed into a solid mass, which allows the plug to withstand shock when pumped to touchdown, while also retaining its ability to be drilled out. The core is completely encased in rubber and has a solid base to prevent separation.
The Bottom Rubber Plug has a core of cast aluminum that is PDC drillable. After the plug has completed its wiping of the casing ahead of the cement slurry and seated at touchdown, additional pump pressure will rupture the rubber diaphragm at the top of the core, allowing slurry to continue to its destination.
