Casing head, type ОКО1-21-146 (168)х245

Purpose

The casing head, type OKO 21-146 (168) x245 is designed for suspending the production casing, tying the upper ends of the casing pipes, sealing the casing annulus and monitoring the pressure in it.

Possibilities

• Casing head installation on the well allows:
• drilling for production casing through the piping body installed on the surface casing;
• installing well control equipment on the piping body through the adapter flange;
• unloading production casing directly into the piping body;
• ensuring solution circulation when cementing through channels in the suspended coupling;
• monitoring pressure in the casing annulus;
• installing X-mass tree on the wellhead coupling.

Advantages

• Wide range of standard sizes for casing options.
• Small size and low cost.
• Reduces expenses when drilling due to the simplicity of the piping and well control equipment installation.
