Construction of the FH 150 Hydro-Geological Drilling Facility with Additive Manufactured Markers Through 3D Printing

Abstract

The washing head is the most important sub-assembly in a water well drilling installation, and ensures the operation of the installation on the principle of "hydraulic rotary drilling with direct circulation of drilling fluid", whereby, inside the rotating drill rod assembly is injected, through the washhead, drilling fluid from the discharge of the drilling mud pump, which is fed from a pit (pit) dug below ground level.
