Tubing head spool:
1. Tubing head structure
Tubing head is usually a spool with both flanged ends，which is set on the top flange of casing head to hang tubing hanger and seal the annular space between the tubing string and oil-layer casing and which consists of tubing head spool and tubing hanger.

2. Functions:
1) hang the tubing string inside well;
2) seal the annular space between tubing and casing ;
3) give a crossover to connect casing head downwards and to connect x’mas tree upwards;
4) provide both side outlets in tubing head spool body through which to execute injection and well-wash operation.

3. Tubing hanger
Tubing hanger is an assembly to support tubing string and seal the annular space between tubing and casing,which is connected with tubing and seated into tubing hanger spool by tubing gravity. It is convenient to operate and replace wellhead so that it is widely used for intermediate depth well and common well.
