Application

 

1. Hole Opener

1. Initially, drillers embark on creating a smaller hole, subsequently expanding it with a hole opener. This conventional drilling technique is pivotal when the drilling machine exhibits lower power or when the end-hole dimensions are substantial.

This is especially common in scenarios where drilling machines possess limited power or when the final hole size is notably large.

2. Our expertise allows us to craft the hole opener and tailor solutions based on the rock's hardness, desired drilling depth,

the size of the pilot hole, and the dimensions of the end-hole.

3. In instances where tricone bits are utilized as pilot bits, the hole opener is transformed into a robust rock bit. This configuration of hole opener with tricone pilot bits is frequently utilized in specialized well drilling projects with unique size requirements.

This approach is particularly effective in drilling wells with special size specifications.

4. The reamer is expertly crafted, primarily featuring four or more intricately designed cones.

5. Its cutting structure is enhanced with premium tungsten carbide hard facing or cutting-edge tungsten carbide inserts,

featuring advanced formulas and innovative techniques that significantly boost the wear-resistant properties of the reamer, ensuring durability and efficiency.

6. The pilot component is a high-performance tricone bit,

7. Seal and lubrication: Engineered with a high-performance HNBR O-ring for superior bearing seal and complemented with advanced grease for optimal lubrication.

8. Product Applications: Perfectly suited for large-scale well drilling, mining operations, and infrastructure projects where precision and reliability are paramount.

9: Recommended Drilling Parameters: Please be advised that the size and number of cones are meticulously determined according to the customer's specific requirements, ensuring a custom-tailored solution for every project.

Customer requirements are always at the forefront of our design considerations.

 

2. Advantages of Hole Opener Bits

In directional crossing operations, typically employed in unexcavated projects, the process unfolds in three critical steps:

1. Oriented hole operation, 2. Hole opening, and 3. Pipe pulling.

The hole opening is notably the most demanding task in this sequence. However, the pivotal element in this operation lies in the careful selection of the hole opener,

which must be aligned with the operational equipment and the geological formation at hand to ensure optimal performance and success.
