API 9 5/8" Oil Well Cementing Plug

Cementing plug for oil well

Description:

Top cementing plug and bottom cementing plug are respectively set at the top and the bottom of double plug cement head before using. When top cementing plug moves down and gets to the top of float collar or impact ring, top cementing plug and bottom cementing plug impact against each other, then the pressure of wellhead release. Float collar and float shoe ward off the backflow of slurry. Cementing is finished.
Characteristics:
1. Special non-rotational device design allowing the plug to drill out quickly;
2. The material of plug body -butadiene rubber. The material of plug core is aluminum alloy. So they can be drilled through by PDC drill bitand roller bit.
3. Precisely mold design
4. The top cementing plug has a solid core; The bottom cementing plug has an air core, and is separatedby a layer of rubber diaphragm.
