The cement head is very important wellhead equipment during the cementing job, which is used for mud circulation, plug dropping and mud injection. Its union is connected to mud line, with the bottom end connected with casing or drill pipe. The cement head usually consists of single-plug cement head, double-plug cement head and drill-pipe cement head.
Drill-pipe cement head also has simple type Model 620 and Model 621 with manifold, mainly used for liner cementing, which is determined by the actual requirement. The simple type usually has a retainer pin, with a union at the bottom which is used for mud circulation, the top with a union port used for mud injection. This is the simplest type of drill-pipe cement head; some is also mounted with a plug indicator near the retainer pin, or a lift sub at the top, which are for the facilitation of the job. The drill-pipe cement head with manifold plug valve has the same function with the simple one, just only for improving work efficiency and user-friendly. |
