Cementing tools are used in the oil and gas industry during the cementing process to ensure proper placement and sealing of cement between the casing and the wellbore. Some common cementing tools include:

1. Centralizers: These tools are used to centralize the casing within the wellbore, ensuring even distribution of cement around the casing. They come in various designs, such as bow spring centralizers and rigid centralizers.

2. Float collars and float shoes: These tools are installed at the bottom of the casing string and contain a check valve that allows cement to flow down but prevents it from flowing back up. They help in maintaining the integrity of the cement column and prevent contamination of the cement during the cementing process.

3. Cementing plugs: These are used to separate different fluids during the cementing process. They are typically made of rubber or composite materials and are inserted at specific intervals in the casing string. They help in displacing drilling mud or spacer fluids with cement and ensure a proper cement bond.

4. Cement baskets: These tools are used to prevent the cement slurry from channeling or bypassing in the annular space between the casing and the wellbore. They are typically placed above and below the zone to be cemented and act as a barrier, forcing the cement to flow through the perforations or the desired zones.

5. Squeeze tools: These tools are used in squeeze cementing operations to repair or seal off zones that are leaking or not properly cemented. They allow for the injection of cement into specific areas of the wellbore to improve well integrity.

These are just a few examples of cementing tools used in the oil and gas industry. The selection of tools depends on the specific well requirements and the objectives of the cementing operation.
