Description

mechanical stage cementing tool /hydraulic stage cementing tool

>>Hydraulic stage tool meets the challenges of cementing holes at any angle with a hydraulically opened port system.

>>Stage tool designed specifically for horizontal completion.

>> It is specifically used for Primary cementing in deep vertical or high deviated horizontal-well conditions.

>>It reduces total hydrostatic pressureon weak formations to prevent lost circulation during cementing.

>>Clear surface indications of opening and closing pressures provide safer and more efficient operations.

>>The opening pressure of the stage tool can be adjusted at rig site to meet well requirements, providing operational flexibility.

The machanical stage cementing collar features inner-closing configuration,in which the circulating port is opened with free-fall or pumping-down plug.The closing plug drives the closing sleeve to shut the circulate port.

The Machanical Stage Collar Features:

1.The machinery double stage cementer can be permanently self-locking in the closing position,with inner-closing structure.

2.The pressure-relief design prevents fluid trapping and compression between the opening device and the closing plug during the closing phase.

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

4.The inner seats which are made of the nitrile rubber/aluminum material and the anti-rotation structure are easily drillable.

5.With pumping-down plug,it is used in the operation of continuous cementing.
