6) Photos
7) Application
Our cementing displacement plug is specially designed with a positive wiping action to ensure that the casing is clean.
The top cementing displacement plug is designed to exert continous pressure on the casing wall.
The fins and tail section of bottom plugs provide positive wiping action. Fins also serve as a seal while cementing.
8) Structure of Cementing Displacement Plug:
The core is made of nylon or aluminium or phenolic resins, depending on the application and well conditions.
The plug is made of high performance materials-- nitrile rubber.
9) Using Method of Cementing Displacement Plug:
Place bottom plug before injecting cement, and pump the scrape to clean the well-wall. After all is set, build the pressure of 2-4MPa till the rubber diaphragm is broken, and thus circulation is formed. Then inject the cement, place the top plug, pump, set the pressure, and well cementation comes to an end.
