Horizontal directional drilling HDD drilling machine hole opener High quality oil and gas well drilling

Describe:

The changeable gear rock drill is suitable for large-diameter non-excavation construction of large-diameter non-excavation pipeline laying by large-scale drilling rigs. It is suitable for a variety of rock formations. The reaming diameter can reach Φ300-2200mm.

The wheel body is reliable in connection with the wheel body, and it is convenient to disassemble, without large-scale special hydraulic equipment, and the wheel body can be easily replaced by a manual wrench.

The same body can be reused, and wheels of different specifications can also be installed. Under normal circumstances, four wheels of different sizes can be replaced, and one body can be used for four-size hole construction, which greatly saves construction costs.

Applications

1. The driller always drills a small hole first, and then enlarges it with a hole opener, which is a routine

Drilling technology when the power of the drilling machine is low or the end hole is overdrilled

2. Hole openers and solutions can be made according to rock hardness, drilling depth, and drilling size

Guide hole, end hole size

3. If the tri-cone bit is fixed as a pilot bit, the hole opener will be a rock drill bit, and the hole opener and tri-cone bit are always suitable for drilling of special sizes.

4. The reamer is mainly composed of four or more cones

5. The cutting structure adopts high-quality tungsten carbide hard surface or high-quality tungsten carbide blades

Use formula and network technology to improve the wear resistance of the reamer

6. The pilot is a triangle drill

7. Sealing and lubrication: high-performance HNBR O-rings are used for bearing seals, and high-grade grease is used for lubrication

8. Product application: suitable for large wells, mining and infrastructure applications

9. Please pay attention to the size and number of cones for the recommended drilling parameters

Features:

1. Suitable for medium to medium hard formations with high fragmentation resistance (hard shale, sandstone, etc.)

2. The drill bearing is a non-sealed roller bearing.

3. The tip of the palm is welded with hard surface, and the carbide blade protection gauge is pressed into the head OD.

4. The surface of the cone gauge is reinforced with cemented carbide press blocks.

FAQ:

1. What is the quality of the drill bit?

A: We have many series of rock drill bits with different quality grades and different prices.

We believe that a suitable tool with a higher cost-effectiveness is the most important. For example, our high-quality rock drill bits are not cost-effective for water well drilling, because water well drilling rigs cannot drive super rock drill bits to their best performance. But for very deep wells, what about high-quality grades? Rock drill bits are cost-effective, even if their prices are much higher. So it’s best to tell us as much as possible about the details of the project, and then we provide suitable solutions and quotations, usually 2 or 3 solutions to choose from.

2. How to send an inquiry?

A: It is best to send us the detailed specifications of the product; it is best to attach some photos for better understanding. If you have no experience in the drilling field, for example, many customers don’t know the IADC code, please feel free to tell us about the applications such as oil/gas/geothermal/HDD/waer/mining, well depth, average rock hardness, and then we will make suggestions and solutions Program.
