How does A Sonic Drill Works?

Categories :Wastewater pumps

We all have to admit that with the help of machines, doing our works have become easier. Achieving the desired results with the best quality is now made possible. When it comes to drilling, a sonic drill becomes very instrumental. Sonic is an advanced kind of drilling that employs the use of high-frequency resonant energy that is generated inside the sonic head in order to advance a core barrel into sub-surface formations. When the drilling happens, this resonant energy is being transferred down the drill string to its bit face at different sonic frequencies. The string simultaneously rotates to evenly distribute the impact and energy.

Such resonant energy is then generated inside the sonic head with the help of two counter-rotating weights. Then a pneumatic isolation system helps prevent the resonant energy from being transmitted to the drill rig and directs the energy down.

The driller is the one that controls the resonant energy that has been generated by the head’s oscillator. This is done in order to match the formation encountered to acquire optimum drilling productivity. Since the energy coincides with the natural frequency of the drill string, it is when resonance happens. As a result, energy at its maximum amount is delivered to the face. Also. The soil friction that is adjacent to the string is minimized, thus resulting in faster penetration.

 

Benefits

Less power, fewer problems

As a result of reduced friction, sonic drilling requires lesser power to get the same kind of effect like that with conventional drilling. Such a unique characteristic helps prevent torsional forces in the drilling string. One more benefit of high sonic frequency application is the ease of retrieving the string, even in boulders and rapidly expanding clays and other difficult decisions. All casings, drilling rods, and tooling are then pulled easier and faster.

 

Sonic drilling is equal to clean drilling

There are times when you would like to avoid using a drilling mud, water or air while drilling. The use of a sonic drill does not really require drilling mud or air while drilling. Such makes it a more favored method for geo-construction, geotechnical, as well as environmental applications. In addition, there are projects where drilling could get dry in during overburden situations.

Environmental projects could benefit from having significant savings with the use of best-drilling methods. Such kinds of projects would require enough amount of money and time to properly get rid of investigation derived waste.

In the case of mining projects, particularly a leach pad, putting additional air or water is a kind of disturbance and could actually affect the soil’s mechanical properties. In times of extreme cases, it could even cause erosion that can lead to failures like a partial landslide. This is why it always a must to use the best machine and method to use for such a project.
