  • China
  • Wooden Case

 

Free-fall Opening Plug

1. The shut-off baffle is installed in the casing collar, one joint above the float collar.

 

1.     

First-Stage Plug

The first-stage plug is used to isolate the first-stage cement and drilling fluid. On the end of displacement,the first-stage plug lands and effects a seal against the shut-off baffle.

 

3. Featuring streamline shape and filled with lead, the free-fall opening plug can quickly free-fall to the lower sliding sleeve. When pressure is applied to the casing, it can open the circulation ports.

 

Shut-Off Baffle

4. The closing plug is used to isolate the second-stage cement and drilling fluid. When running to the upper sliding sleeve, it effect a seal in the stage cementer. Pressure is applied to the casing and the circulation ports are closed.

 

5. The pump-down opening plug is used for continuous cementing operation and in deviated wells. It can open the circulation ports directly and quickly, whereas the free-fall opening plug needs longer time waiting for falling.

 

Pumping-Down Opening Plug
