Applied to drill complex rock formations
Drills at any angle
Good straightness of borehole
Maximum depth of borehole is 150Meters
Eccentric Casing system
Drilling through formations with loose,unconsolidated material always comes with problems such as
the bore hole cave-in collapse.How to avoid these problems?
With years of field pratice and reserch,Teamwhole had developed its eccentric casing system application for
strata with silt,sand or small size pebbles.With its simple struture,easy operation and reliable performace,this system can advance the casing easily for depth within 30 meters.And it's retrievable with long serive life.
