How does a sonic drill carry out its function so well? It works by directing high-frequency vibrations from its drill head towards the drill string, or sometimes called the pipe, to the drill bit. The machine operator for a sonic drill has the liberty to make needed adjustments to the resonance frequency to make it suitable to the type of soil or rock being drilled into. Normally, the frequency would be anything between 50Htz and 15Htz.
Such arrange of resonance will bring about the fluidization of the soil or rock found at the drill area or surface. This is comparable to a hot knife that you use to cut through a block of cold butter. What sonic drilling does is reduce friction drastically allowing for the drilling to catch on its speed, 3 to 5 times faster when compared to conventional drilling methods.
The reason why there is a need to reduce the amount of friction produced here is to negate the use of lubricants or mud for lubrication purposes during drilling. This necessitates only the use of compressed water or air to help out in flushing out the cutting debris. With sonic drilling rigs, you’d be able to make drilling work to a depth of about 100 to 300 ft.
Why Sonic Drill?
Here are the top reasons why this drilling method is a top choice among project managers today.
- It will not put the environment in harm’s way.
Unlike other methods of drilling, sonic type of drilling will only make use of compressed air or compressed water in order to flush out its cutting debris up to the surface of the project site. It actually eliminates the need to introduce lubricant or mud into the hole. By this measure, you are reducing the chances of environmental contamination with less amount of produced waste overall.
- High level of efficiency.
Reduced amount of friction in sonic drilling will easily translate to faster rates of drilling job. With this method of drilling the amount of disturbance to the surrounding environment is reduced. Thus, it also signifies faster clean-up work soon after the project has been completed and need to wrap-up.
- Lower costs
Generally speaking, sonic drill rigs are smaller in size, and for that reason, they use less horsepower. This will pave the way for a lower fuel cost required to run a rig facility. Furthermore, less waste and faster rate of drilling process will also translate into lower overall costs and attractively much lower labor costs on the drill site.
Machine operators of a sonic drill rig, they have the liberty to make needed adjustments on the frequency of vibration. This is paramount in drilling so that the machine and its vibration will match the soil type. By this virtue, the sonic drill is able to proceed with its operation even through a mix of “difficult” soils where traditional drills are likely to get jammed causing delays on the project’s timeline or bring the whole project to an unexpected standstill.
- Reduces waste by up to 80%
Sonic drilling technology is employing the use of an innovative casing advancement system. But it sifts through the slough, by which process the sample integrity is improved even through dolomite, limestone, sand and a host of other unconsolidated material.
Practical applications for sonic drilling technology can be found in both shallow and deep drilling applications where you need to have no less than an undisturbed core sampling through different kinds of geological pattern is required. This powerful technology that comes with this drilling type presents many benefits and advantages over other drilling methods or techniques.
