According to the insiders from the industry and sonic drill rig manufacturers, sonic drilling is way more advantageous than other alternative methods of drilling techniques. For a better understanding of this, we must get a good glimpse of how sonic works. This will help give us a mental picture of how it is being carried out.
How Sonic Drilling Works?
Sonic drilling will send an extremely high-frequency vibration and this will be coming from the drill head, passing this through the drill string, then to the drill bit. The machine operator or the staff manning the sonic drill rig will make necessary adjustments to the resonance frequency so that it can accommodate the soil or type of rock being drilled into. The frequency here is usually between 50 hertz to 150 hertz.
The level of resonance created here will help induce fluidization of the soil or rock at the drilling surface. In more ways than one, this is comparable to how a hot knife can pass through a nugget of cold butter. By reduced friction through sonic drilling, it allows for sonic drilling speeds to reach at least 3 – 5 times faster as opposed to traditional methods of drilling.
The amount of reduced friction here will negate for the use of lubricants or mud while drilling process is still ongoing, where the only thing that would be required would be water to flush away the cuttings or sometimes compressed air can be utilized also. Sonic drill rigs are powerful enough for it to be able to dig through depths up to 300 feet or 100 meters.
Capabilities of Sonic Drilling
- Continuous core sampling with 6 to 8 in core barrels
- PQ3 and HQ3 diamond coring
- Downhole packer for aquifer testing or injection
- Pitcher barrel sampling
- Zone sampling or otherwise known as isolated groundwater sampling
- Other alternative sampling strategies that can be looked into upon request
- Drilling depths that can go deep up to 700 ft. The borehole diameters of which could be anywhere between 6 to 12 inches
- Angle drilling capabilities that are from vertical to 45 degrees
- Rubber track-mounted rigs are capable of climbing a 30-degree angle from horizontal
- Rubber track skid support steer unit, this is usually supplied with every sonic rig
Design Features for Success
Each component of the sonic drilling rig is geared towards maximizing efficiency, accuracy, and safety so you can seamlessly get the job done right the first time. The arms control panel highlights an intuitive layout which lets the staff operator carry out several tasks effortlessly.
Pumps, speeds, and feeds are precisely dialed in with the aid of electronic controlling system. As for the rod handling system, it will help in enhancing productivity and safety, while at the same time it lowers the likelihood of the occurrence for operator fatigue.
According to sonic drill rig manufacturers, while the working principle behind the sonic drill is giving us a complicated, difficult to- deal with the impression, the truth here is the machine itself is pretty easy and simple to operate. The driller is only required to add in vibratory energy to the standard rotary motion. He has the full liberty to choose for himself the frequency to which in his best judgment will give the drilling rate he is looking for.
