Classification of API 11B Sucker Rod
The classification of the API 11B sucker rod is mainly based on factors such as its material, steel grade, diameter, length and thread specifications:
1. Classification by material:
Alloy steel rod: mainly made of alloy steel material, with high strength and good comprehensive performance.
Other materials: According to special needs, other materials can also be used, such as stainless steel.
2. Classification by steel grade:
- Class K Rod: Suitable for Wells with moderate intensity requirements.
- Class C Rod: High mechanical strength, suitable for deeper Wells or applications requiring higher load capacity.
- Class D Rod: Higher strength and better corrosion resistance for use in extreme conditions.
- Class H Rod: Designed for high-load applications with excellent fatigue strength and durability.
3. Classification by diameter and length:
Different diameter rod: such as 15.88mm (5/8 inch), 19.05mm (3/4 inch), 22.23mm (7/8 inch), etc., to adapt to the size requirements of different Wells.
Different lengths of rod: 9140mm (30 ft), 8000mm (26 ft), etc., to meet different drilling depths and process requirements.
4. Flexible sucker rod: carbon fiber composite sucker rod, wire rope sucker rod.
5. Other types of sucker rods: electric sucker rods.
The Role and Application of API 11B Sucker Rod
The API 11B sucker rod is mainly used in the rod production system of the oil field, and is an important part of connecting the surface pumping unit and the underground pumping pump. It is widely used in various oilfield environments, including onshore and offshore oil fields, and is one of the indispensable equipment in the process of oil exploitation.
The API 11B rod has a wide range of applications and important operational requirements in rod production systems in oil fields.
Through proper installation, reasonable maintenance, correct operation and the observance of precautions, it can ensure its safe and efficient operation.
1. Improved pumping efficiency: The API 11B rod is a key part of the oil recovery process by connecting the pumping unit to the pump and lifting the oil from the well to the surface.
2. Adapt to complex environment: It has good corrosion resistance and wear resistance, can adapt to a variety of complex oilfield environment, such as high temperature, high pressure, high salinity and so on.
3. Ensure safe production: It has high reliability and safety, and can ensure safe production in the process of oil exploitation.
