eccentric casing systems
Overburden Casing Drilling System DTH Bit is very popular in
international water well and ore drilling field.
Features
Hardening treatment of the part's surface
with longer operating life and excellent anti - wear properties.
Structural optimization
Strengthen the structural strength, easy to operate
Superior performance
Stable and reliable performance, high drilling speed
When the bore-hole is complete, the casing is retrieved to be used
again.
Pros
Rapid removal of cuttings;
No use of drilling mud;
High penetration rate, especially in resistant rock formation
(e.g. basalt);
Easy soil and groundwater sampling during drilling;
Possible to measure yield estimate at selected depth in the
formation;
Advantage
ous in unconsolidated formations with a high risk of caving (this
is probably the most important feature).
