What is Aluminum Alloy Cement Collar Float?
The body of the Aluminum Alloy Cement Collar Float is typically made of high-grade steel, but the internal components, such as the valve and any anti-rotation inserts, are crafted from a drillable aluminum alloy. It serves the same basic functions as any other float collar—guiding casing, preventing cement backflow, and providing a seat for cementing plugs—but its unique material offers some distinct advantages.
Features of this Aluminum Alloy Cement Collar Float
- The valve is made of drillable materials. The valve body is 6061 aluminum alloy, and the spring is made of tin bronze. Its overall performance meets the requirements of API RP 10F IIIC standards.
- Equipped with high-temperature-resistant rubber components, it has excellent corrosion and erosion resistance.
- Threading and inspection comply with API 5B standards.
- The valve is not only suitable for conventioal technical casing and production casing but can also be used in deep wells, ultra-deep wells, and special process wells. The maximum pressure rating of the valve is up to 70 MPa.
How It's Different from Other Float Collars
The use of aluminum alloy for the internal components provides several benefits:
- Fast and Efficient Drill-Out: Aluminum is a softer metal than steel, making it much easier to drill through. This significantly reduces the time required to drill out the float collar, saving valuable rig time and lowering costs.
- PDC Bit Protection: Unlike some other materials, aluminum alloy does not damage or prematurely wear down expensive PDC bits, which are commonly used for this operation.
- Lightweight: While the float collar is a small part of the overall casing string, using a lighter material can slightly reduce the overall weight of the string, easing handling and installation.
- Meets High-Pressure Requirements: Despite being a softer material, the aluminum alloy components are designed to withstand high-pressure cementing operations, with some models rated to handle pressures up to 10,000 psi or more.
In summary, the use of aluminum alloy in a cement collar float is a material choice driven by the need for optimal drillability without compromising the structural integrity required for a successful cementing job. This makes it a popular choice for modern drilling operations that prioritize efficiency and the protection of downhole tools.
