Frequently Asked Questions
How about the common packing?
If there is no special packing demand, we use our standard packaging method. Products are first placed in small cartons, then consolidated into larger cartons to ensure complete protection during shipping.
Do you have different types for different rock formations?
Yes, we offer different bit types specifically designed for various rock hardness levels and geological characteristics.
Can you manufacture products according to our drawings or samples?
Yes, we have professional molding departments and experienced R&D teams capable of custom manufacturing based on your specifications.
What is an overburden well?
Overburden wells are typically constructed in geological materials above bedrock, composed of sands and gravels. Most water wells include well screens that allow groundwater entry while filtering out sand and other materials.
What is the purpose of surface casing?
Surface casing provides blowout protection, isolates water sands, prevents lost circulation, and often provides adequate shoe strength for drilling into high-pressure transition zones.
How far can you directional bore?
Maximum lengths and hole diameters depend on specific geotechnical conditions. The effective outside range for heavy rig horizontal directional drilling is up to 3,000 meters.
