Description

The working principle of a three cone drill bit is mainly based on its unique cutting structure and mechanical principles. During the drilling process, the three cone drill bit transmits rotational force and drilling pressure through the drill pipe, achieving efficient fracturing of the formation.
Firstly, the three cones of the drill bit rotate around the bottom of the hole, while each cone rotates around its own axis. This composite motion allows the cutting teeth on the teeth to fully contact the rock formations, generating strong cutting forces.
Secondly, when the tooth wheel rolls at the bottom of the well, the cutting teeth on it sequentially impact and press into the formation. During this process, the cutting teeth crush and shear the formation rocks into small pieces. This crushing effect mainly depends on factors such as the shape, arrangement, and material hardness of the cutting teeth.
In addition, drilling fluid plays a crucial role in the drilling process. Drilling fluid is injected through the drill pipe to lubricate and cool the drill bit, while carrying debris out of the bottom of the hole. This not only helps to maintain the good working condition of the drill bit, but also improves drilling efficiency.

Company Profile

Crossing Bit, a leading manufacturer of PDC bits and tricone bits in northern China, has exported its high-quality drill bits to more than 30 countries, demonstrating its strong market influence and exceptional product strength.

Crossing Drilling Tools has not only established a sterling reputation in the drilling, construction, HDD (horizontal directional drilling), exploration, water well, geothermal, mining, and oil & gas industries, but has also gained widespread recognition from customers for its exceptional product reliability and quality. We are committed to developing and producing a range of high-quality tools, including tricone bits, PDC bits, tricone cutters (single rollers), PDC reamers, drag bits, and HDD hole openers, to meet the diverse needs of our customers.

Our meticulously designed PDC bits are specifically optimized for directional drilling. With exceptional stability, durability, and "directional" friendliness, they are able to precisely maintain the bit's position in narrow and complex pay zones, ensuring smooth drilling operations.

This unique steerable bit technology, combined with high ROP (rate of penetration), sets Crossing Bit apart from the competition and establishes it as a leader in the industry.
