There are many kinds of cementing tools, such as: sealing ring, rubber ring, valve body, valve seat, Y-type high-pressure tee, pipeline clamp, copper sleeve, copper pad, copper ring, copper ring, anti-return joint, High pressure pup joints, unions. Today's main explanation is the cementing tool - anti-rotation cementing plug.

Anti-rotation cementing plug has its unique use and structural characteristics, see the following brief introduction:
     Uses: When cementing, isolate the cement slurry and mud to prevent the mud from infiltrating into the cement slurry and affect the cementing quality.

     Structural features: The cementing rubber plug series is divided into ordinary cementing rubber plugs, upper and lower rubber plugs for double-plug cementing, and upper, middle and lower rubber plugs for double-stage cementing.
     1. Standard cement plugs are suitable for various floating hoops and shoes; anti-rotation cement plugs are suitable for anti-transformation floating hoops and shoes.

     2. Double-stage sealing and scraping wings are designed on the top and bottom plugs.

     3. Scraping wings made of wear-resistant materials.

     4. The anti-rotation rubber plug is designed with an anti-rotation mechanism, which can greatly improve the drilling and removal speed.

     5. PDC bit or roller bit can be drilled.
