The series of cementing rubber plugs are divided into ordinary cementing rubber plugs and anti-rotation cementing rubber plugs, upper and lower rubber plugs for double-plug cementing and upper, middle and lower rubber plugs for double-stage cementing. Standard cement plugs are suitable for all kinds of floating hoops and shoes; anti-rotation cement plugs are suitable for anti-transformation floating hoops and shoes. The top and bottom plugs are designed with dual-stage sealing and scraping wings. The scraping wings of polyurethane have good cleaning sleeve function and abrasion resistance. The anti-rotation rubber plug is designed with an anti-rotation mechanism, which can greatly improve the drilling and removal speed.
Single-stage double-plug casing cementing is the most common cementing method for offshore drilling. It uses double-casing rubber plugs (top and bottom plugs) for cementing. The process flow is shown in the figure. Generally, common casing plugs are used for cementing on jack-up platforms or jackets, while SSR plugs are used for cementing on floating platforms. When using single-stage double rubber plug cementing, the casing string accessories are mainly composed of floating shoes, floating hoop, centralizers and rubber plugs.
