CEMENTING HEAD, 142 series , single plug, OILFIELD TOOLS, WELL TOOLS, WELLBORE ACCESSORIES
Cementing head
Cementing head is a manifold system that is installed on the top of the casing which allows the cement slurry to be pumped from the cement unit down any of the type of casing string. The cement head is also used for releasing the top and bottom cement plugs.
A “cement head” is screwed into the top casing collar or landing joint, depending on the type of casing cementing job. The discharge side of the downhole pump and the cement head are connected by a series of articulated or straight sections of high-pressure steel pipe, also known as “treating iron”
Single plug cementing head
Just before pumping the cement, the bottom plug is inserted through the container, followed by the top plug, which rests on the releasing pin. When cement activity mixing has been completed, the top plug is released before displacement starts. The downward movement of the plug into the casing is indicated by the lever mechanism below the releasing pin.
