6 FAQs about [Down-the-hole drill operating platform]
What is downhole drilling?
Downhole drilling is a sophisticated field where operators leverage cutting-edge tools and methodologies to access critical resources as global energy demand continues rising. The industry’s ongoing progress with innovative drilling technology will be crucial to meet the world’s hydrocarbon needs now and into the future.
What is down-the-hole (DTH) drilling?
Down-the-hole (DTH) drilling has made it easier for contractors to drill wells faster and more efficiently, and to transition from dirt boring to rock boring just by adding a compressor and hammer to the drill bit.
How does DTH drilling work?
With DTH drilling, contractors can change the drill that they were using for the current directional bore to a rock drill when they encounter rock by connecting the drill with a compressor and a steerable hammer. Well drilling also needed changes to be made to rotary drilling when the well needed to take a turn.
What is the difference between rotary drilling and DTH drilling?
The lower rotational speed reduces vibrations to the drill head and rig. In relation to pure rotary drilling, DTH drilling is faster, due to the more focused and intensified stresses imposed on the rock, and does not require sophisticated drilling mud preparation, handling and cleaning systems.
How to drill a hole with a drill bit?
Specific operation method: whenever drilling begins, the operator must swing the drilling tools gradually to the bottom of the hole. When the frequency down the hole reaches 700~900 times/min and the pressure of the drilling tool on the drill bit reaches about 3kN, it can be the best impact speed.
What is a DTH drill rig?
A down-the-hole drill, usually called DTH Drilling Rig, is basically a mini jackhammer screwed on the bottom of a drill string. The speedy hammer activity breaks hard stone into little flakes and dust and can be dismissed evident by the air exhaust in the DTH hammer.
