ADVANTAGE & BENEFIT
Sonic drill and Sonic drilling have a lot of Advantages compared with Conventional drills and drillings, which create a lot of Benefits for Sonic users.
SONIC TECHNOLOGY AND AIR DAMPER
The head contains the mechanism necessary for rotary motion, as well as an oscillator, which causes a high frequency force to be superimposed on the drill string. The drill bit is physically vibrating up and down in addition to being pushed down and rotated. These three
combined forces allow drilling to proceed rapidly through most geological formations including most types of rock. Additionally the air damper is also incorporated in order to confine the alternating forces to the drill string.
Comments from sonic users:
Sonic rig allows us to drill much faster and cheaper, which keeps the per foot costs of drilling down. Not only for geothermal, good for environmental investigations and water well drilling.
With a tight working space, a tight budget and silty, sandy ground beneath them, a sonic drill rig completed four bore holes, each to a depth 61m, all in a day.
What impresses most people is the ability of sonic rig to drill dry. Because it is so much less intrusive, particularly when talking about Dam remediation.
“163m x 6-5/8” water well was drilled with sonic ring bit in 2 days. The ground was too soft by conventional rotary drilling. Before the completion, 10-3/4” x 12m and 8-5/8” x 88m were drilled and cased by sonic drilling.
76m x 136 holes were drilled in 3 months. Its versatility is what makes the sonic drill a leader.
26” tri-cone bit was used with sonic vibration up to 40m on medium hard rock formation just in 4 hours.
A competitor’s rig drilled only 15m in 2 weeks. Sonic finished 23 geothermal holes in 2 weeks.
68mm O.D. core of hard rock up to 180m was taken by TS118 sonic wireline system.
Note: TS118 sonic wireline system was designed for soft ground formation.
20” hole was drilled up to 100m by tri-cone bit with sonic vibration. The penetration speed was much faster than the one only by rotary motion.
New sonic ring bit has longer life and performs faster drilling speed. Although the price of the new ring bit is higher than the original bit, it is worth it.
Note: It was developed for soil to medium-hard rock formation.
2-3 holes (55m deep hole) were drilled per day and 120 holes were completed. It was about 6 times faster than conventional drilling.
Silica sand is too porous for mud rotary drill. The sonic is the only rig that can do this, and I’ve used almost all of them including other sonic drills from other manufacturers.
In geothermal drilling, sonic drill allows you to case the hole, insert the loop and grout, and then vibrate the casing back out in one operation.
92m was drilled in 2 hours and 3 minutes.
More hole, better to use sonic drill.
In overburden, the vibratory action causes the surrounding soil particles to fluidize, thereby allowing effortless penetration. In rock, the drill bit causes fractures at the rock face, creating rock dust and small rock particles, which facilitates advancement of the drill bit.
In many instances the drilling and coring of rock and earth can be accomplished without the use of any drilling fluid whatsoever. This is an important requirement for environmental drilling projects. Compressed air, drill mud, or plain water can be utilized to remove the cuttings and speed up the operation further, depending on the application that the machine is used for.
Due to the mechanisms to create the vibration force and to transmit it to the drill bit, the noise is quieter than the one of Hydraulic Rock Drill, DTH or so. The patented Air Damper also contributes to the noise reduction. Furthermore a sonic drill head of SONIC-NEO equips Silent Proof Cover around.
Basically the heavy weight on bit is not important to sonic drilling while the rotary drill requires it. Too much weight on bit effects unnecessary borehole deviations. For sonic drilling, since the combined forces allow drilling to proceed rapidly, there are less chances to occur the borehole deviation
Sonic drill and sonic drilling can be used for a lot of drilling applications. The capability of SD-100 (33K) drill head to drill horizontally and the compact size expands the usage. Here are some examples.
Geothermal installation hole drilling, Environmental investigation, Anchor and Grout hole drilling, Piling, Water well drilling, Blast hole drilling and so on.
Optionally rotary drill head for diamond coring can be installed beside sonic drill head. Then the drill unit will be more
BENEFITSfor sonic users
Due to the advantages such as Faster Drilling Speed and Capa bility to Drill and Case the Hole Simultaneously, you can complete the project in shorter period compared with the one by conventional drilling method.
Our sonic drill equip Drill Head Tilting System, Hydraulic Rod Breaker and optionally Hands-Free Rod Handling System. These devices translate to Labor Saving and Safer Operation.
Some of the most valuable things are Time and Manpower. As a result of the use of our sonic drill, it is able to shorten the work period and save the labor. The advantages of sonic drill and sonic drilling will be more profitable in the near future.
In some projects, only our sonic drills can pass the regulations, be allowed to enter some job sites and complete the projects. The required equipment and tools are minimized thanks to the advantages and the drilling capability of our sonic drills.
Also the versatility gives the sonic users more opportunities to get more jobs.
Environmental interests have been always discussed in this drilling industry and should be focused on furthermore in the future. The capability to drill dry or with smaller amount of circulation fluid and mud contributes to the one of solutions. Low Noise may be the one as well.
The patented sonic drill is outstanding in its ability to provide continuous, highly representative, relatively undisturbed core samples through most geological formation including boulders and bedrock through a combined forces of Rotation and Vibration.
Due to the capability to core dry or with a small amount of circulation fluid, the waste can be reduced by up to 80%.
In accordance with our policy of constant improvement, we reserve the right to amend design, materials, specifications and prices at any time without prior notice.
Drilling capability varies according to many factors. The introduced drilling capability and customers feedbacks on the website are only examples and these are not guaranteed.
