How Do I Choose a Drilling Rig?

Nov. 29, 21

A drilling rig is a piece of construction equipment used to drill holes in the earth's surface. They can vary greatly in size: they can be huge structures or light enough to be moved manually by one person. Drills can take samples from deposits and test the physical properties of rock, soil, and groundwater. They can also be used for underground installations: tunnels, shafts, or pipelines.

 

When do I need to drill?

Many jobs require drilling, for example

 

Drilling: whether to access groundwater or oil.

Geothermal drilling: to obtain and extract heat from the earth.

Piling to support buildings on unstable ground: up to 2,000 mm in diameter and up to 70 m deep.

Truck Water Well Drilling Rig

Mini-pile drilling, especially for the reinforcement of existing structures: between 150 and 200 mm in diameter and up to 30 m deep.

Quarry blast drilling.

The continuous auger holds the borehole wall by means of auger-driven chips.

The drilling is usually carried out vertically, but can also be horizontal or directional, for example for placing anchors.

 

How do I choose a drilling rig?

You may need a drilling rig for a variety of applications, such as drilling wells to access natural resources (water, oil, geothermal energy, etc.), building foundations, drilling holes in mines, taking samples from the surface, etc. It is necessary to determine what the drilling rig will be used for and what kind of terrain it will mainly operate on. Depending on the terrain you can choose between different types of drilling rigs: rotary drilling rigs, percussion drilling rigs, submersible drilling rigs, top hammer drilling rigs (with high hammers), etc.

To make the best choice, it is important to determine whether the rig will be used for your core business or for occasional operations, and in particular whether you want to take advantage of the latest innovations or whether a machine that has proven its performance for decades might be worthwhile for you. Safety, reliability, and ease of use are also important factors to consider and are directly related to each other. Using a machine that is reliable and easy to operate according to the manufacturer's recommendations increases user safety.


It is also important to define the type of movement you need. There are automatic crawler rigs and truck-mounted or trailer-mounted rigs, which need to be powered by a generator or the truck carrying them. Once you have defined the type of machine you need, you can calculate the required dimensions based on the diameter and depth of the borehole.


What type of drilling rig should you choose?

There are two main types of drilling rig: self-crawling and truck or trailer mounted. If it needs to move at low speed over uneven areas or very loose ground, you will need to choose a tracked crawler water well drilling rig. The stability of a drilling rig depends on the surface area of the tracks. Therefore, the wider the track, the more stable the rig will be. However, wider tracks will wear out and damage the ground more quickly when moving, especially when turning. 

Crawler water well drilling rigs can travel at a speed of around 4 km/h. They are therefore better suited to jobs that require little travel.

Truck- or trailer-mounted water well drilling rigs are not autonomous in terms of movement or their energy source, which may come from a transport truck or a separate generator. However, they are much cheaper than tracked rigs.
