Two Stage Cementing Tool

 

The XYZ series two stage cementing tool comes with inner-close type design. As soon as the closing sleeve goes down, the circulation port is shut.

 

Features

1.      The opening pressure for the two stage cementing tool is adjustable, and the operation is not subject to the hole angle.

2.      Circulation port can be opened, closed and operated, without causing fluid compression in the cavity.

3.      The inner diameter of upper/lower sub is the same as that of casing, but smaller than that of the closing sleeve.  The chances of damages to the closing sleeve can thus be minimized.

4.      All the components are made of drillable rubber or aluminum materials. The two stage cementing tool comes with rotation locking system for easy drilling.

 Accessories of Two Stage Cementing Tool

The accessories of DSG and SJG series two stage cementing tool include first stage plug, free-fall opening plug, closing plug, shut-off baffle and pump-down opening plug. These components, made of rubber and aluminum, are readily drillable.

 

1. The shut-off baffle is fixed in the casing collar above the float collar.

2. The first-stage plug is used to isolate grout and drilling fluid. At the end of displacementthe plug lands and effects a seal against the shut-off baffle.

3. The streamlined free-fall opening plug, filled with lead, can quickly free-fall to the upper sliding sleeve. After applying certain pressure to the casing, the plug can open the circulation ports.

4. The closing plug serves to separate the second-stage cement and drilling fluid. Then it comes to the upper sliding sleeve to form a seal in the stage cementer. As you continue to pressurize, the closing sleeve goes down and the circulation ports are closed.

5. The pump-down opening plug suits use for continuous cementing operation and in deviated wells. It can open the circulation ports directly and quickly.
