Water well drilling rig shock absorber installation video

Why do drill rigs need shock absorbers?

Shock absorbers act as a buffer, helping reduce these vibrations effectively. Without shock absorbers, excessive stress on components such as drill rods, machine rotation heads and boom joints. It can lead to premature wear and failure (especially if not shock absorption technology is not already built into the drill rig)

Can a shock absorber sub be placed between drill collars?

The studies show that the placement of a shock absorber sub between the drilling bit and the drill collars can: Almost eliminate the vertical oscillations. It can reduce drill collar connection failures in hard formations by dampening the high fluctuating buckling.

What is a DTH shock absorber?

Down-the-hole (DTH) drilling has revolutionized industries like construction foundation and water well by enabling efficient and precise operations. However, one important component often overlooked is the DTH shock absorber. These simply designed tools play a vital role in ensuring your drilling process runs smoothly and efficiently.

What are drill bit oscillations?

What Are The Drill Bit Oscillations? A shock absorber sub or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses while drilling. It does this by converting the kinetic energy of the shock into another form of energy (typically heat), which is then dissipated.

How do shock absorbers work?

Absorption of Vibrational Energy: Shock absorbers simply fit between the DTH hammer and the first drill pipe and utilise elastomeric heavy duty materials to absorb and dissipate vibrational energy, thus reducing its transfer to other sensitive components.

What is a shock absorber sub?

Most shock absorber subs are a form of dashpot (a damper that resists motion via viscous friction). So, You can consider the shock sub is the first line of defense against drill string vibrations that we encounter while drilling hard formations.
