Oil Well Cementing Tool Oilfield Cementing Tools Single Plug Casing Cement Heads With Manifold Oilfield Tool
Description
Cementing head is a device fitted to the top joint of a casing string to hold a cement plug before it is pumped down the casing during the cementing operation.
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”
Double plug cementing head
Heads capable of storing multiple plugs are preferred over those just carrying single plugs for operational convenience, as the use of more than one plug requires the opening of the head to insert a second (or even a third) plug after circulating the drilling fluid and launching the bottom plug. This allows not only the build-up of gels in the annulus, having an adverse effect on fluid displacement efficiency, but also cement-free fall. The risk of sticking the casing (pipe sticking) is also increased if reciprocation is stopped to allow the insertion of the additional plug (or two).
