Factors To Consider When Buying A Water Well Drilling Rig

Choosing a water well drilling rig requires careful consideration before you sign on the dotted line. This is not an impulsive decision. While price is the most common consideration for many people, there are many other aspects to consider - some of which may outweigh the impact of price. Consider service and support, training and quality; and don't forget the ever-important slurry pump.

Whether you are buying new or used, a little research and education will help determine the right drill for your needs.

Training.

Proper training is vital to the success of your operation, so work with a manufacturer that provides an overview of safety and operation.

Operating a new piece of equipment presents a number of potential challenges. If operators have not worked on water well rigs before, or if they have but lack experience with the make or model, training is essential.

Quality.

If you want a drill that performs well and lasts, don't cut corners on materials and components.

A higher-quality product may cost more, but when it performs better, causes fewer problems, and lasts longer, the few dollars are worth it. In addition, lower quality bits usually have little resale value compared to higher quality models.

Welded steel frames

Look for a manufacturer that is open about the quality of materials they use and the assembly process. Look for heavy-duty welded steel frames and thick drill pipes to ensure the rig can withstand challenging conditions. Some manufacturers cut corners by using thinner steel. This can cause the frame to bend or twist while driving, or wear prematurely due to corrosion in hot, humid climates.

Having strong water well drill rods and other sturdy components can also make a huge difference. Some manufacturers cut costs by offering inferior water pipes instead of heavy-duty ASTM A500 specification drill pipes. While drill pipe can cost 10 times as much as water pipe, a broken pipe can mean a major setback if your rig goes 100 feet underground in a remote area and you hit hard soil or rock. The situation can take hours to resolve or mean moving to a new site and abandoning the pipe to correct it. Look for manufacturers that use at least 1 ¾ inch diameter drill pipe and connections made from heat-treated alloy steel. Lower quality drill bits often use ¾ or 1-inch water pipes for lower strength applications.

With quality components, the drilling operator can also limit access to the repair shop for replacement parts for water well rigs.

 Mud Pump

The secret is in the mud pump

The power of your system and the depth of your hole are directly related to the quality and power of your centrifugal pump.

The mud pump is an essential component of the water well drilling process.  A powerful centrifugal pump is needed to flush the well of drill cuttings to obtain the proper drilling depth and high-quality borehole. Once your pump can no longer flush out the rock chips, you have reached your maximum depth capacity. The power and efficiency of the mud pump add to this depth and you can drill deeper compared to other methods.

Some people may choose to cut corners and buy a cheaper mud pump from another manufacturer, which may result in poor performance by buying a pump with specifications that don't fit their particular rig. Choosing an OEM mud pump means that it will provide the best performance when paired with a drilling rig.

Choosing well water drilling equipment

A knowledgeable drill bit manufacturer will work with you to identify the ideal bit to meet your needs. Soil type, geographic location, and intended use will help determine which drill rig is best. Work with a company that will support your drilling mission at every step of the process. A true partnership will deliver the best results.

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

1. Price

• Machine price is the key factor for people to select suitable drilling rig, it is one time investment. The machine&#;s price increased along with increasing of hole diameter and depth.
• From Drilling method point of viewDTH drilling rigcoring drilling rig
• From mobility point of view, truck mounted drillscrawler mounted drills

2. Operational Cost

• Operational cost significantly affects the profit people can gain during drilling business. The net profit is the money driller get from well user from water well drilling minus operational cost.
• The operational cost contain people salary,cost of casing, mud and fuel as well as maintenance cost of drilling rig.
• From type of drilling machine point of view, Down The Hole(DTH) drilling rig has higher operational cost than rotary drilling rig working with mud pump. Because, the air compressor is needed for DTH drilling rig and its oil consumption is very much higher. The vertical drilling rig

3. Drilling efficiency

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

4.Drilling Method

• From working principle of drilling machine point of view,there are mainly 3 drilling method:
  • Down The Hole drilling method which needs to work with air compressor. It is great method for rock condition.
  • Rotary drilling with mud pump
  • Auger drilling, it do not need air compressor and mud pump during drilling. But it only can drill the soil, clay and sand.
• From drilling process point of view, we have 2 drilling method:
  • Direct circulation drilling
  • Reverse circulation drilling, it needs dual wall drilling pipe. The drilling fluid go through the space between inner wall of outer tube and outer wall of inner tube. For cobble stone and sand, soil geological structure, it is most efficient drilling method.

5. Service after Market

• The service of after market is another key point for drilling rig selection. During the drilling operation, there will be issues happens on rig like components broken, mis-operation of rig. All this needs timely and professional guide from rig manufacturer. Otherwise it will affect rig user&#;s business

6. Availability of Spare Part

• People needs to consider the availability of spare parts when they buying drilling machine. It is part of operational cost. If the spare parts is not easy to get, it means you have to pay more to get it and cost longer time. All of this will definitely influence drilling business profit.

7. Safety

• The safety is first thing when selecting rig, including safety for operator, service people as well as people around the rig both during drilling and travelling.
• Therefore, the safety guard, emergency stop, dust collector is needed to protect people from death or injured.

8. Environmental Protection

• Nowadays, all countries take environmental protection to a higher level, so the engine emission level and noise level needs to be considered when selection rig.
• Buyer needs to refer to the country or area standard code where the rig will be used

Above is just some basic knowledge during drilling rig selection. It can be guide for business starter when they plan to buy rig.
