6 FAQs about [Diesel down-the-hole drill working video]

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 a down hole drill used for in drilling?

A down hole drill, or DHD, is used to drill overburden and rock. Casing bits and reamers are used to drill the initial holes for installing casing and to provide an annulus for grouting. The following instructions are for a stabilizer to be used. If a stabilizer is not required, use a drill pipe from the carousel in its place.

What are the disadvantages of a DTH drilling rig?

Conventional drilling rigs have cumbersome groundwork in bedrock drilling, frequent lifting and lowering of the drill, large labor consumption, slow speed, and comprehensive calculation of capital consumption, and these disadvantages are difficult to change. DTH drilling rigs mainly use compressed air.

What makes a good drilling machine?

Robust design is built to last and adds safety to daily work. An accurate control system with simple icon displays makes drilling easy. Clear gauges for drilling parameters, compressed air, feed and rotation pressure are some of the features that also guide the operator for more productive drilling.

How fast can you drill a well with DTH?

With DTH, it was now possible to turn 2-4 degrees curves and drill the well’s tangent up to 30 degrees or greater averaging 300 feet per hour, where rotary drilling would progress 30-40 feet per hour.
