Cementing Rubber Plug

‌Sunrise Petro: A Pioneer in Cementing Rubber Plug Manufacturing in China

The cementing plug has the functions of isolating cement slurry, cleaning the casing wall, and preventing cement slurry pollution. After the plug collides with the float collar, it can accurately indicate the position of cement slurry replacement and the sealing performance of the casing.

The upper and lower rubber stoppers are generally used as a complete set. The upper rubber plug separates the upper cement slurry from the mud to prevent contamination of the cement slurry, while replacing the cement slurry into the annulus.

Description

At present, cementing rubber plugs are widely used in normal production operations. In drilling operations, after the technical casing is run, cementing operations are carried out. At this time, rubber plugs are used to replace the cement pumped into the casing with mud into the annulus of the casing.

In deep wells and special wells, it can be combined with casing float shoes to improve the safety of cementing operations. During the process of running casing, achieving unidirectional flow of drilling fluid in the annulus can prevent cement slurry backflow during the cementing process and achieve pressure relief and waiting for setting after cementing collision, which helps to improve the bonding quality between the cement sheath and casing; At the same time, by injecting drilling fluid into the casing string to adjust its buoyancy, the suspended weight of the casing meets the design requirements for casing operation.

Application

Before injecting cement, first insert the lower rubber plug, pump and scrape to clean the wellbore wall, which is used to separate the lower cement slurry from the mud and prevent contamination of the cement slurry. After collision, due to the hollow nature of the lower rubber plug, the pressure is suppressed by 2-4 MPa, which breaks the rubber film and provides a channel for the cement slurry to establish circulation. Then, inject cement, insert the upper rubber plug, pump and press, and the cementing is completed.

Advantage

Sunrise has extensive experience in manufacturing rubber plug, and our products have the following advantages.

The upper and lower rubber plugs are designed and manufactured according to the SY5394-91 standard. The core material is made of aluminum alloy or polymer material, which has good drillability. The rubber stopper is made of imported nitrile rubber, which is oil resistant, acid and alkali resistant, and has good scraping effect.

1. The cementing plug series is divided into ordinary cementing plugs and anti-rotation cementing plugs, upper and lower plugs for double plug cementing and upper, middle and lower plugs for double stage cementing.

2. The top and bottom plugs are designed with dual stage sealing and scraping wings. The scraping wings of polyurethane have good cleaning function and wear resistance of the casing.

3. Can work with PDC drill bit or roller drill bit.

4. Standard cement plugs are suitable for various floating hoops and shoes; Anti-rotation cement plugs are suitable for anti-transformation floating hoops and floating shoes.

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