How to Select Water Well Drill Bits for Different Geological Layers When Drilling with a Water Well Rig?

On the journey of exploring groundwater resources and promoting socio-economic development, water well drilling rigs and their complementary water well drill bits are undoubtedly indispensable pioneering forces. As a leader in the steel and diamond material processing field with over a decade of experience, GREAT has been leading the development trend of the water well drilling rig and drill bit industry since its inception with its excellent technical strength and innovation capability. Today, we will delve into how to scientifically and reasonably choose water well drill bits under different geological conditions to ensure the smoothness of drilling operations.

Water Well Drill Bits: The Soul of Drilling Operations

In drilling engineering, water well drill bits are not only the sharp tools that penetrate deep underground and through rock layers but also the key to the efficient operation of the entire drilling system. Without suitable drill bits, even the most advanced drilling rigs can only sigh in lamentation at the rock. Therefore, choosing a water well drill bit that suits the current geological characteristics is crucial for improving drilling efficiency, reducing costs, and ensuring safety.

GREAT: Excellent Provider of Water Well Drill Bits

Since its establishment, GREAT has focused on in-depth research and application of steel and diamond materials, especially in the field of water well drill bits, where we have accumulated rich experience and technical reserves. Our product line covers a variety of drill bit specifications ranging from 3" to 36", and rock reamers from 8'' to 72'', including but not limited to PDC bits, tricone bits, roller cone bits, diamond core bits, bi-center bits, PDC reamers, and hole openers, meeting diverse needs under different geological conditions. Notably, our water well drill bits not only come in a complete range but also achieve breakthroughs in composite sealing and metal sealing technology, ensuring stable performance under different working conditions.

Precise Matching, Stratified Approach

Facing complex and variable geological conditions,  GREAT understands the principle of "one key opens one lock." Therefore, when selecting water well drill bits, we always follow the following principles to ensure precise matching of the drill bits with geological characteristics:

Soft Rock Formations: Dual Pursuit of Speed and Efficiency

In soft rock formations with good drillability, drilling speed is often fast, but the problem of cuttings discharge cannot be ignored. At this point, GREAT recommends using four-winged water well drill bits, whose wide blade design can effectively increase the cuttings volume and improve cuttings quality, ensuring the continuity and efficiency of drilling operations. Meanwhile, our drill bits are optimized in design, with carefully calculated tooth rows, tooth numbers, tooth heights, and carbide tooth shapes, ensuring fast cutting capabilities while extending the drill bit's service life.

Hard Rock: Dual Test of Strength and Durability

When facing the challenge of hard rock, the strength of the drill bits and inserts becomes the primary consideration. The TCI bits provided by GREAT, made from high-strength, high-toughness carbide materials combined with optimized carbide tooth design, can withstand significant load impacts, ensuring stable operation even in hard rock. Additionally, we offer customized services, adjusting drill bit parameters according to customer needs to meet specific geological drilling demands.

Clay Layers: Dual Strategy of Cuttings Discharge and Clogging Prevention

The loose characteristics of clay layers can easily cause clogging of cuttings discharge holes, affecting drilling efficiency. To address this issue, GREAT launched side-cuttings discharge drill bits, whose unique side-cuttings discharge design can effectively prevent the clogging of discharge holes, ensuring smooth drilling operations. Additionally, our water well drill bits have undergone special treatment for sealing performance, further reducing the chances of clay intrusion into the drill bits, extending the drill bit's service life.

Tough Rocks: Dual Guarantee of Safety and Efficiency

When drilling in tough rocks, safety is the foremost consideration. The wedge teeth drill bits of GREAT, with their unique tooth design, can maintain high cutting efficiency while effectively reducing friction and vibration between the drill bits and rocks, lowering the risk of tooth breakage and drop, ensuring the safe operation of drilling tasks. Additionally, we offer a variety of IADC codes for customers to choose from, such as 437, 517, 537, 617, 637, etc., to meet the drilling needs of different tough rocks.

In the journey of water well drilling through different geological layers, choosing the appropriate drill bit is a key step towards success. With its rich product line, excellent technical strength, and customized service solutions, GREAT provides customers with comprehensive solutions.
