Product Description

PDC **9.8mm Petroleum Drill Bit: The Pioneer of Efficient Rock - breaking

Product Overview

The PDC **9.8mm petroleum drill bit, with a diameter of **9.8mm, is meticulously designed for petroleum drilling operations. It adopts advanced Pol ycrystalline Diamond Compact (PDC) technology, which perfectly combines the high hardness and wear - resistance of diamond with the high strength and toughness of cemented carbide, demonstrating excellent performance in various petroleum drilling conditions.

Structural Design

• Cutting Teeth: High - quality polycrystalline diamond compacts are carefully selected and inlaid on the blade wings in an optimized layout. The unique shape and arrangement of the cutting teeth enable efficient cutting during drilling, reduce the wear of the cutting teeth by the rock, and extend the service life of the drill bit.

• Blade Wings: They are designed according to the characteristics of different formations. The streamlined structure ensures that the drill bit is evenly stressed during the drilling process, reduces torque fluctuations, and effectively improves drilling stability.

• Gauge Protection Structure: It is equipped with strengthened gauge protection strips, which are made of cemented carbide or treated by surface hardening. They have excellent wear - resistance, can effectively maintain the regular diameter of the wellbore, and prevent the drill bit from reducing the diameter during the drilling process, ensuring the smooth progress of the drilling operation.

Working Principle

Under the combined action of the drilling pressure and torque, the PDC cutting teeth penetrate into the formation. With their high hardness and sharp edges, they strongly shear and break the rock. As the drill bit rotates and moves forward continuously, the cutting teeth keep scraping the rock, breaking the rock into small pieces of cuttings, which are then carried to the surface by the drilling fluid.

Performance Advantages

• Efficient Drilling: In soft - to - medium - hard formations (such as mudstone, shale, sandstone, etc.), the drilling speed is significantly increased compared with traditional drill bits, which can significantly shorten the drilling cycle and reduce the comprehensive cost.

• Long Service Life: Its excellent wear - resistance enables the drill bit to withstand long - term drilling wear, reducing the number of trips in and out of the well, and improving the continuity and reliability of operations.

• Good Stability: The optimized blade wing design and gauge protection structure ensure that the drill bit maintains good stability during the drilling process, reducing the vibration and swing of the drill bit and improving the quality of the wellbore.

Application Scope

It is widely used in various drilling operations of vertical wells, directional wells, and horizontal wells during the petroleum exploration and development process, especially suitable for petroleum drilling in soft - to - medium - hard formations. Whether in on - shore oil fields or offshore oil platform drilling operations, the PDC **9.8mm petroleum drill bit can provide reliable guarantees for your drilling projects with its outstanding performance.
