3 Blades Concave PDC Bits PDC Drag Bit for Water Well Drilling
Product Description:
PDC drill bit is a commonly used drilling tool for oil drilling. PDC drill bits are composed of multiple Polycrystalline Diamond Compact cutting elements and are widely used in geological drilling, rock cutting, and oil extraction. This article will introduce the structure, principle, and application fields of PDC drill bits.
Blade wings are an important component of PDC drill bits, typically made from diamond cutting elements. The number, shape, and layout of blade wings play an important role in the drilling performance and quality of the drill bit. Blade wings are generally evenly distributed to ensure uniform wear of the drill bit during the drilling process.
Features:
1.Efficient rock breaking: In soft-to-medium hard formations (such as mudstone, sandstone, and shale), the mechanical drilling rate (ROP) is 2-5 times higher than that of a three-cone bit, making it particularly suitable for long sections of horizontal shale gas wells.
2. Long service life: The composite segments have excellent wear resistance, and a single drill bit can advance up to several thousand meters (for example, in shale gas wells, the advance distance can exceed 5,000 meters), reducing the number of drilling operations.
3. Low vibration and low noise: Rotational cutting is more stable than toothed-wheel impact, which can reduce the risk of drill bit fatigue damage and is suitable for precise trajectory control in directional wells and horizontal wells.
4. Cost Advantage: Although the single unit price is higher than that of a three-cone drill bit, due to the greater drilling depth and higher efficiency, the overall drilling cost can be reduced by 30% to 50%.

Applications:
1.Shale gas horizontal wells: In the development of shale gas in North America, PDC drill bits combined with screw drilling tools achieve efficient drilling of long horizontal sections (over 3,000 meters) with single drill bit penetration records exceeding 7,000 meters.
2.Shallow oil reservoirs and coalbed methane: In loose sandstone, coal seams and other soft formations, serrated PDC drill bits can quickly penetrate and maintain a smooth wellbore.
Packing and Shipping:
PDC Reamers are packaged with the utmost care and shipped safely and securely to ensure they reach their destination in optimal condition. The reamers are placed in sturdy cardboard boxes with foam padding inside for extra protection. They are then placed in an outer carton, which is sealed and labeled with the product name and a shipping address. The carton is also labeled with the weight and size of the reamers. The Reamers are then shipped via a trusted courier service to ensure that they arrive on time and in good condition.
