Water Well Drilling Rig Manufacturer
For a water well drilling rig, the general requirement: simple configuration, less energy consumption, easy operation, more moveable, muti-functional, small size. In a real application, the drilling rig selection has to be based on the stratum, hole diameter, and hole depth as well as the drilling method.

1. Price
Machine price is the key factor for people to select a suitable drilling rig, it is a one-time investment. The machine’s price increased along with increasing of hole diameter and depth.
From the drilling method point of view, a DTH drilling rig is more expensive than a coring drilling rig, and the price of a hydraulic drilling rig is higher than a vertical shaft drilling rig, which is a more mechanical drilling machine. From a mobility point of view, truck-mounted drills cost more than crawler-mounted drills.

2. Operational Cost
Operational cost significantly affects the profit people can gain during drilling business. The net profit is the money driller gets from well users from water well drilling minus operational cost.
The operational cost contains people's salary, cost of casing, mud, and fuel as well as maintenance cost of the drilling rig.
From the type of drilling machine point of view, the Down The Hole(DTH) drilling rig has a higher operational cost than a rotary drilling rig working with a mud pump. Because the air compressor is needed for DTH drilling rig and its oil consumption is very much higher. The vertical drilling rig(mechanical driven) is more economical compared to a hydraulic drilling machine.

3. Drilling Efficiency
Drilling efficiency depends on the stratum, skills/experience of the operator, the type of drilling machine, and the drilling method.
For rock conditions, the most efficient way is to use a down-the-hole drilling rig working together with the air compressor.
For soil, clay, and sand condition, the best way is to use a drilling rig with a mud pump.
For cobblestones, the reverse circulation system is the most suitable drilling method. It just needs to add a set of reverse circulation drilling tools to the existing drilling machine.

4. Drilling Method
From the working principle of the drilling machine point of view, there are mainly 3 drilling methods:
Down The Hole drilling method needs to work with an air compressor. It is a great method for rock conditions.
Rotary drilling with a mud pump is a more economical drilling way and fits very well for soil, sand, and clay stratum, for rock its drilling speed will be lower compared to DTH drilling.
Auger drilling, does not need an air compressor and mud pump during drilling. But it only can drill the soil, clay, and sand.
From the drilling process point of view, we have 2 drilling methods:
Direct circulation drilling in which the drilling fluid(air or mud) goes through the drill rod and takes the cuttings via the space between the outside of the drill rod and the wall of the hole.
Reverse circulation drilling needs a dual-wall drilling pipe. The drilling fluid goes through the space between the inner wall of the outer tube and the outer wall of the inner tube. For cobblestone and sand, soil geological structure is the most efficient drilling method.

5. Service after Market
The service of the aftermarket is another key point for drilling rig selection. During the drilling operation, there will be issues that happen on the rig like components broken, misoperation of rig. All this needs timely and professional guidance from the rig manufacturer. Otherwise, it will affect the rig user’s business.
6. Availability of Spare Part
People need to consider the availability of spare parts when they buy drilling machines. It is part of operational cost. If the spare parts are not easy to get, it means you have to pay more to get it and cost a long time. All of this will definitely influence drilling business profit.

7. Safety
Safety is the first thing when selecting a rig, including safety for operators, service people as well as people around the rig both during drilling and traveling.
Therefore, the safety guard, emergency stop, dust collector is needed to protect people from death or injury.
8. Environmental Protection
Nowadays, all countries take environmental protection to a higher level, so the engine emission level and noise level need to be considered when selecting rig.
Above is just some basic knowledge during drilling rig selection. It can be a guide for business starters when they plan to buy a rig.【Whatsapp/Wechat/Phone/Skype】+8613613856800
