6 FAQs about [Dual tire down-the-hole drill video tutorial]

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 dual rotary drilling?

Initially, the dual rotary technique was perfected for use in water well and construction applications. In recent years, the technology has evolved, and new rigs and design features have improved performance and broadened its range of applications. In typical drilling operations, the drill bit is advanced slightly ahead of the casing.

How does a dual rotary drill work?

Once the casing has been set to the required depth, the dual rotary drill can continue to drill open hole in the same manner as a conventional top-drive air drill without tripping out to change the bit. The lower drive feeds on two directly connected hydraulic cylinders (outside left and right).

What is a DTH directional drill?

The DTH system is easy and quick to adapt to a directional drill and is considered one of the best and most effective methods to drill high-quality holes that are stable and straight. It can be done on both hard and soft rock and is extensively used in the construction, oil and gas, and water well industries.

What is a dual rotary rig?

The distinguishing feature of a dual rotary rig is a lower rotary drive, which is used to independently advance casing up to 40 inches, depending on the drill model. The lower drive transmits pulldown, pullback and rotational forces to the casing. A carbide-studded shoe, welded to the bottom casing joint, cuts through the overburden.
