Casing Head
Casing headis a kind of new product which is designed according to customers' requirements and applied in all deep wells and completion operation. lt is mainly used to fix wellhead connect casing string and seal, and control the pressure of casing annular space. The casing head assemblyconsists of the casing head, valve spool, casing hanger and bypass valve.
wellhead casing headis made of low-alloy steel with good loading capacity and H2S penonnance. The connection type is divided into welded types: threaded type and slip type. The casing hanger is equipped with cons-shape sealing mechanism and BT sealing mechanism. Its sealing mechanism is superior under the force of gravity, which can be used more conveniently 2nd quickly in the field. Its structures can be divided into mandrel and slip types.
Features of Casing Head:
Application of Casing Head：
The casing head is installed at the upper end of the surface casing string, and is used for suspending the casing of the casing other than the surface casing and the wellhead device component of the annular space of the sealing casing. The main functions are as follows:
- Special operation: a. The cementing quality is not good. The side hole can be filled with cement. b. When acidizing and fracturing, the pressure balance liquid can be injected from the side hole.
