Product Description
                                             API 9 5/8" Non -rotating cementing plug

The Quick Drill  casing cementing wiper plugs have two (2) unique (patented) internal designs which makes for Faster-Better-Cheaper cement wiper plugs.

The phenolic core of the wiper plugs has a breakage design for early breakage of the core with the bit without reducing the effectiveness of the core. The second unique design is the controlled expansion engaging the wall of the casing like a packer, compressing and locking the outer body and fins of the wiper plug firmly against the inner wall of the casing with only 1000 psi differential pump pressure on the plugs. 
1) Types Available: Conventional standard plugs and non-rotating plugs are available;
2) Standard: API
3) API and ISO certified
4) Specifications: 4 1/2''---20''. More special sizes or combination are available as requested.
5) Material: Rubbers and Phenolic Resins.

6) Application
Our cementing plugs are specially designed with a positive wiping action to ensure that the casing is clean.
The top cementing plugs 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. 
7) Structure:
The core is made of aluminum or phenolic resins, depending on the application and well conditions.
The plug is made of high performance materials such as rubbers or phenolic resins. 

8) Using Method:
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.

 Torque tests of the compressed 7" Quick Drill™ wiper plug at room temperature exceeded 2000 ft lbs of torque resistance. With time and wellbore heat the bonding to the inner wall of the casing becomes greater. Quick Drill™ wiper plugs saves rig time as actual recorded drilling time for a set of 7-5/8" plugs was less than 10 minutes.  easy drill high strength cement aggregate in their patented Float Equipment, assures a good combination of rig time savings plus an excellent opportunity at no secondary cement squeezing.
