The methods to reduce wear and tear of petroleum drill pipes during use mainly include the following aspects:
1. Standardized operation: Operators must receive professional training to obtain correct operating methods and skills. When performing drill pipe operations, strict adherence to various operating procedures should be followed to avoid any negligence or errors. At the same time, the selection and inspection of drill pipes are also very important links. Suitable drill pipes should be selected for the working conditions, and their quality should be good without any wear or damage.
2. Regular maintenance: Regular inspection and maintenance of drill pipes can promptly identify and address potential problems, avoid problem escalation, and also extend the service life of drill pipes, reducing drilling costs. The maintenance interval should be reasonably set according to the usage environment and working conditions of the drill pipe, especially in high temperature, high pressure, and highly corrosive environments. The maintenance interval should be appropriately shortened.
3. Improving drill pipe materials and processes: Developing high-quality materials and using high-strength materials such as lightweight aluminum alloys as drill pipe materials. At the same time, improve the processing technology, do a good job in heat treatment, and make the internal structure of the drill pipe more refined and perfect.
4. Control the verticality of the drilling hole: If the verticality of the drilling hole is high, the contact surface between the drill string and the hole wall will correspondingly decrease, and the situation of rotating around the axis will increase, thereby reducing the degree of friction between the drill string and the hole wall.
5. Improving drilling fluid performance: Using solid-free drilling fluid to reduce the viscosity and density of the drilling fluid, in order to reduce erosion and wear on the drill string. At the same time, increasing the pH value of drilling fluid, inhibiting the corrosion of acidic gases on drill pipe columns, and using deoxidizers to reduce oxidative corrosion on drill pipe columns.
The comprehensive application of these methods can effectively reduce the wear and tear of petroleum drill pipes during use, and improve the efficiency and quality of drilling operations.
