6 FAQs about [How to modify a down-the-hole hydraulic drill rig to drill casing]

How do casing and drilling work together?

Casing and drilling simultaneously improve drilling efficiency. If you need to speed up drilling time, adding a casing advancement system to your drilling toolbox will go a long way to improving productivity and the drill time on your project. Selecting the right system will depend on the drilling application or purpose.

Can a drilling casing be used to drill through overburden?

Engineers are continually challenged with the risk of hole collapse when faced with drilling through overburden and unconsolidated formations. That is why it is prudent to use drilling casings to drill through overburden while advancing the drilling casing and protecting the hole at the same time.

What is a drilling casing?

A drilling casing is a type of drilling tool that enables you to case and drill simultaneously. It can be used with rotary percussion drilling where the impact of the hammer drives the casing down the wellbore. Installing casing, while drilling, minimizes the risk of holes collapsing and enables projects to be completed faster and more efficiently.

What is a drill rig used for?

Drill rigs are used to bore huge holes deep into the earth’s surface to insert piles that are the base upon which a structure is erected. Installed casings act as load-bearing support, while in friction piles the casing is only used as an element to keep the hole open during the drilling process.

How to choose a casing advancement system for top hammer drilling?

DTH is a common method of drilling deep holes with greater precision. It is commonly deployed in well drilling and straight piling projects. If this is the preferred method of drilling, you should select a casing advancement system that offers 114,3–1 219 mm diameter-wide components. Casing advancement for Top-hammer drilling

Why do you need a drilling casing?

Drilling in these formations is often challenging and the risk of collapsing, hole deviation, and failure to reach the intended depth is a real concern for drilling contractors. Installing drilling casing as the hole is drilled helps to stabilize loose, or unpredictable formations, and shore up the hole.
