Mechanical and Hydraulic Shock Absorber

Products Introduce

Introduction:

The mechanical-hydraulic shock tool is a drilling shock absorber used while drilling, installed close to the drill bit with disc springs and silicone oil as damping elements. The tool mitigates or absorbs axial vibrations from the drill bit and drill string. It features variable stiffness characteristics, providing two distinct stiffness levels within a single damping stroke. The tool offers excellent maintainability, high load resistance, and an extended service life. It enables optimal coordination between weight on bit and rotational speed, thereby improving drilling efficiency. It is suitable for drilling operations in hard formations, gravel layers, and interbedded soft and hard formations.

Features and Benefits:

★ It employs silicone oil damping to simultaneously absorb both axial and torsional impacts.

★ It optimizes the coordination between weight on bit and rotational speed, effectively enhancing drilling efficiency.

★ It is particularly suitable for adverse drilling conditions such as hard formations and gravel layers.
