HSC-A Hydraulic Stage Cementing Collar

HSC-A Hydraulic Stage Cementing Collar

HSC-A hydraulic stage cementer is designed with inner-closing structure, in which circulation ports are opened by fluid pressure difference. The closing plug drivers the closing sleeve to shut the circulation ports.


Features of HSC-A Hydraulic Stage Cementing Collar

1. Opening pressure can be adjusted and it is not affected by well deviation.

2. Circulation ports are opened by pumping. No fluid trapping and compression while opening and closing circulation ports.

3. The I.D.of upper/lower sub is the same as that of casing, but smaller than that of closing sleeve, which can minimize chances of damages to the closing sleeve.

4. The inner parts are made of an easily drillable rubber/aluminum material. Both the ope ning and closing seats have anti-rotation mechanism for easy drillout.
