PDC oil drilling bit

Product Description

The following is an introduction to the PDC bit with a diameter of **5.9mm, 5 blades and double - row teeth:

Structural Design

• Blade Layout: The five - blade design makes the bit more evenly stressed during drilling, with good stability. It can effectively resist the lateral force and ensure the accuracy of the drilling direction. At the same time, the chip - removal grooves between the blades are relatively wide, which is conducive to the discharge of cuttings, reducing the accumulation of cuttings at the bottom of the well and improving the drilling efficiency.

• Double - row Tooth Arrangement: The double - row tooth design increases the number and density of cutting teeth. The front - row teeth cut first, and the rear - row teeth follow up to further crush and compact the rock. It realizes a composite rock - breaking mode of cutting and crushing, which improves the rock - breaking efficiency and prolongs the service life of the bit.

Working Principle

Rely on the weight on bit to make the cutting teeth penetrate into the formation, and the torque drives the bit to rotate. The cutting teeth shear the rock like plowing the land, scraping the rock into pieces. It mainly shears the rock, relying on continuous rotation and stable weight on bit. At the same time, a large - displacement hydraulic system is required to clean the cuttings at the bottom of the well to avoid mud - balling affecting the efficiency.

Product Advantages

• High Rock - breaking Efficiency: The composite rock - breaking mode of double - row teeth and the reasonable blade design enable the bit to quickly and effectively break the formation rock, improve the rate of penetration, and shorten the drilling time.

• Good Wear Resistance: PDC cutting teeth have extremely high hardness and wear resistance, which can resist the abrasion of rocks. They can remain sharp during drilling, reduce the wear of the bit, and prolong the service life.

• Strong Directional Ability: The structure design of five blades makes the bit have good directional performance in directional drilling, which can accurately drill according to the designed trajectory and meet the requirements of complex formations and special drilling technologies.

• Stable Working Performance: The reasonable layout of blades and double - row teeth makes the bit evenly stressed during drilling, reducing vibration and impact. It can maintain a stable working state under different formation conditions, improving the safety and reliability of drilling.

Application Scope

• Soft to Medium - hard Formations: Such as mudstone, shale, sandstone, etc. PDC bits can give full play to their shear - rock - breaking advantages and drill quickly.

• Deep and Ultra - deep Wells: In deep and ultra - deep well drilling, the high wear resistance and long life of PDC bits can reduce the number of tripping operations, improve the drilling efficiency, and reduce the drilling cost.

• Directional Drilling and Horizontal Drilling: Its good directional ability and stable working performance make it suitable for well sections of special processes such as directional drilling and horizontal drilling.
