Casing Stage Collar
The stage collar is a mechanical device utilized for two-stage
cementing operations. It primarily comprises a two-stage coupling
body, a first-stage plug, a baffle plate, and either a free fall
opening plug (for non-continuous processes) or a pump-down opening
plug (for continuous processes), along with a closing plug. Its
purpose is to facilitate efficient and controlled cementing
processes.
1. The closing sleeve of the stage collar is equipped with an
out-closing structure and a locking device to ensure secure
engagement once closed.
2. The stage collar is designed to prevent the accumulation of liquid in the loculum, a small compartment or chamber, during opening or closing. This prevents any liquid from obstructing or interfering with the proper functioning of the stage collar during operation.
3. It is essential for the inner diameter (i.d.) of the upper and lower sub of the stage collar to match that of the casing in order to protect its body during drill-out operations when the drill bit goes down. This matching i.d. creates a protective barrier, mitigating the risk of potential damage.
4. All accessories of the stage collar, such as drillable rubber or aluminum materials, are designed to be anti-rotational and facilitate easy drill-out processes.
5. The stage collar can be equipped with a pumping-down plug, enabling efficient execution of continuous processes.
