The cementing head is designed to hold a cementing plug before it is pumped down the casing during the cementing operation. In most operations, a bottom plug is launched before the spacer or cement slurry, followed by the top plug after the spacer fluid. A manifold incorporated into the cement head assembly allows connection of a fluid circulation line.
The double plugs cementing head is a special tool for pumping slurry and releasing plugs. It can couple with two plugs simultaneously, allowing drilling fluid to fill into the casing in turn quickly. This simplifies the cementing operation and prevents cement pollution.
