Oil, natural gas, etc. are now indispensable resources, but the acquisition of such resources requires drilling and exploitation. In drilling operations, the cement head is a very important cementing tool, which is installed at the top of the casing and is connected with the casing and ground manifold. connected. Through the cement head, the staff can complete operations such as circulation, injection of isolation fluid, injection of cement slurry, release of rubber plug, and replacement of slurry. So in the process of drilling and cementing, what are the commonly used cementing heads?
 
Cementing heads are divided into drill pipe cement heads and casing cement heads according to their connection objects.
 
Drill pipe cement heads can be divided into ordinary drill pipe cement heads and rotary drill pipe cement heads according to their functional forms. The drill pipe cement head is connected with the drill tool.
 
Casing cement head is divided into single plug casing cement head and double plug casing cement head. According to the pressure balance method, it can be divided into outer balanced casing cement head and inner balanced casing cement head. The double-plug casing cement head is divided into a long-volume double-plug casing cement head and a short-volume double-plug casing cement head according to the length of the rubber plug cavity. The casing cement head is directly connected with the casing.
