Product Description

Mechanical Two Stage Cementing Collar Coupling

Product Description

 

1. Scope
Stage collar is a kind of mechanical tool used to complete cementing operation into two times, mainly used in the following circumstances:
1.1. Excessive injection of cement at one shot.
1.2. The formation cannot bear gigantic fluid pressure.
1.3. Packoff special strata.
1.4. Avoid occurrence of annual air channeling after cementing work.
1.5. The considerable temperature difference between the upper and lower section makes it rather difficult to adjust slurry performance.

2. Structure

Our stage tool mainly consists of two-stage coupling (body), first-stage plug, shut-off baffle, free-fall opening plug and closing plug.

3. Main characteristics

3.1. It adopts inner-closing structure and locking device on closing sleeve. Lock is reliable after closing.
3.2. The liquid would not occur in the loculum when opening or closing.
3.3. The ID. of upper/lower sub should be the same as that of casing, it can protect the body of stage collar from damaging when the bits going down and doing drill-out operation.
3.4. All the accessories are made in the drillable rubber or aluminum material. They have the function of anti-rotation , it can make drillout easy.
3.5. You can use pumping-down plug to carry out continuous process.
3.6. Apply to the well deflection should be ≤25°
