What are the five key points in selecting a water well drilling rig

1. Drilling depth and geological conditions

Drilling depth: Select the Drilling Rig according to the demand and ensure that the maximum drilling depth is slightly higher than the actual demand (20%-30% margin).

Geological conditions:

Soft formation: choose auger drilling rig or impact drilling rig.

Hard rock formation: choose pneumatic or hydraulic drilling rig with high torque and strong impact force.

Complex formation: prioritize multifunctional drilling rigs with better adaptability.

2. Performance parameters of the drilling rig

Drilling diameter: make sure it meets the wellhead design requirements, the common diameter range is 75-400mm.

Power type: choose diesel-powered or electric-powered drilling rigs according to the operating environment.

Lifting capacity: Ensure that the weight of the drill pipe and drilling tools meets the requirements to avoid jamming during operation.

Torque and speed: hard rock requires high torque and low speed, loose ground requires high speed and low torque.

3. Applicability and mobility of equipment

Field operation: choose tracked or vehicle-mounted drilling rigs, which are easy to move.

Narrow area: choose small and flexible portable drilling rig.

Extended function: such as equipped with Mud Pump, air compressor or coring function, can enhance the scope of application of the drilling rig.

4. Brand and after-sales service

Brand quality: choose a famous brand, product quality and stability are more guaranteed.

After-sales service: Prioritize manufacturers with perfect after-sales service, including parts supply and technical support.

5. Cost and price-performance ratio

Budget range: according to the actual needs of the choice of performance and price balance of the equipment, to avoid over-allocation or under-allocation.

Operation cost: pay attention to fuel consumption, maintenance cost and ease of use of spare parts to reduce the long-term cost of use.

Summarize: according to the drilling demand, geological conditions, equipment parameters, after-sales service and budget comprehensive consideration, choose the water well drilling rig with matching performance and high cost performance.
