Conventional Cementing Plug,Non-rotating Cementing Plug,Self-locking Cementing Plug
Cementing is the work of inserting a certain size of casing string into the well and injecting cement slurry around it to fasten the casing to the wellbore.The characteristics of the cementing plug: After all the cement slurry is injected, the plug is pressed on. It follows the cement slurry downward and is used to scrape the cement slurry adhering to the inner wall of the casing, prevent displacement of drilling fluid and mixing with the cement slurry, avoid contamination of the tail cement slurry, and ensure the quality of the bottom cement bond. When it reaches the choke plate, it shows collision pressure, and the cementing operation is completed. Cement plugs can ensure the separation of cement layers, scrape the inner wall of the casing, and isolate the cement slurry. When the rubber plug is located on the float collar, it can accurately display the mud displacement position and the sealing performance of the casing. Features: Standard cement rubber plugs are suitable for various floating hoops and shoes; Anti rotation cement plugs are suitable for anti transformation floating hoops and floating shoes. Double stage sealing and scraping wings are designed on the top and bottom plugs. Scraped wings made of wear-resistant materials. The anti rotation rubber plug is designed with an anti rotation mechanism, which can greatly improve the drilling speed. PDC bit or roller bit can be drilled and injected: 1. Core material: engineering plastic. Scraping wing material: polyurethane 2. Standard cement rubber plug top plug, X=5, standard cement rubber plug bottom plug, X=6; Anti rotation cement rubber plug top plug, X=3, anti rotation cement rubber plug bottom plug
