Application:
IADC 737 with spherical inserts work for hard with high abrasiveness such as hard limestone,dolomite,firm sands,etc.commonly used in Blasthole Drilling and the water/oil and gas well drilling industry.
Advantages:
1. Versatility: Tricone bits are versatile and can be used in a wide range of formations, including soft, medium, and hard formations. This versatility reduces the need for changing bits frequently during drilling operations.
2. Efficiency: Tricone bits are known for their efficient drilling performance. They typically drill faster than other types of bits, which can reduce drilling time and associated costs.
3. Longevity: The construction of these drill bits is specifically engineered to endure the tough conditions faced during drilling, such as extreme temperatures, intense pressures, and abrasive materials. Their sturdy design guarantees longevity, resulting in extended bit lifespan and decreased maintenance downtime.
4. Automatic Cleaning: Tricone bits are equipped with a unique design that allows for self-cleaning while in rotation, preventing the buildup of debris and cuttings around the cutting edges. This automatic cleaning feature helps to uphold drilling efficiency and minimize the chances of bit blockages or clogging.
5. Drilling in challenging formations: Tricone bits are particularly effective in drilling through challenging formations such as hard rock, shale, limestone, and sandstone. Their multi-cone design and various cutting structures enable them to adapt to different formations, providing consistent drilling performance.
6. Reduced vibration: Tricone bits are designed to minimize vibration during drilling, which enhances drilling stability and reduces wear and tear on drilling equipment. Reduced vibration also improves drilling accuracy and reduces the risk of tool failure.
7. Customization: Tricone bits can be customized based on specific drilling requirements, such as the formation type, drilling depth, and desired performance characteristics. This customization allows operators to optimize drilling operations for improved productivity and cost-effectiveness.
