Figures don’t lie when it comes to the drilling rigs for sale in Australia.
What it is showing us is a sustainable surge in the number of drilling rigs being purchased in years past. It is one of the more tangible proofs that the mineral and oil drilling industry in the country is dynamically growing and more. The second in lead here is the rotary air mud drilling method.
Looming question we have regarding these 2 methods of drilling is which among these two should you consider having? Which among the two will best fulfill your business’ requirements?
The choice of drilling method to use for your upcoming project is not just going to have a big impact on the outcome, but would actually determine the level of success you are bound to have from its use. For this, you need to take into account a number of things such as your project goals. Have you clearly outlined what your project goals are? Other important things you need to consider are geologic conditions and groundwater presence. And then last on the list would be the time table or work schedule that you need to make your team adhere to.
If you happen to have an upcoming drilling project and you reckon that it is going to involve deeper borehole drilling, you must condition yourself as early as now that the work ahead of you will be most challenging due to difficult geologic conditions.
How Do They Work?
With the help of the impact energy created by the hammer combined with the rotation motion, the rotary type of drilling can be advanced. This should naturally crush the encountered ground formation, right at the drill. The formation drill cuttings will be moved and taken away from the borehole with the help of circulating compressed. Another good alternative for this is water.
If drilling proper becomes unstable due to difficult ground formations, bentonite additives can be added to water, which is simply mud. With the help of pressurized air, cuttings can be blown away and push them to the catchment. The water mud can be used to funnel them to the cutting settling pit.
The cuttings will be recycled. To do this, they need to get back to the borehole. Advancing the borehole in sonic drilling can be done with the use of resonant high-frequency vibrations, which will significantly help in fluidizing the ground formation that the drill bit is encountering. The sonic head, which you can find at the topmost part of the drill string will create the vibrations, so it will be able to move in an up and down on the drill string where vibration is at its most intense compared to many other parts of it.
Resonant frequencies become audible and are thus qualified as “sonic” if they reach 50 for up to 200 Hertz. Implementing a certain level of control to manage these frequencies is a must when it comes to making them suitable for use on the type of ground formation encountered and worked on. Rotation motion can be added if you need to get past difficult and hard geologic formations.
Sonic type of drilling can easily find its practical application in the many different types of geologic foundations. You might find it very surprising that it can help you surmount even the seemingly extremely difficult drilling situation. So when trying to look for drilling rigs for sale in Australia
