MSC-A mechanical stage cementer designed with inner-closing structure, in which the circulation ports are opened with free-fall or pumping-down opening plug. The closing plug drivers the closing sleeve to shut the circulation ports.
1. With inner-closing structure, the stage cementer can bring permanent self-locking after closing.
2. 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 smallerthan that ofclosing sleeve, which can minimize chances of damages to the closing sleeve.
4. The inner parts are made of easily drillable rubber/aluminum material. Both the opening and closing seats have anti-rotation mechanism for easy drillout.
5. With pumping-down opening plug, it is used in the operation of continuous cementing.
