High performance Overburden Drilling System for Water Well Casing
Details description:
Stratex was designed as an overburden drilling system that advances
casing while drilling. Collapsing holes tend to be a problem when
drilling through overburden. Stratex is the solution when you need
a cased hole. The patented Stratex overburden S.D.S system was
designed in coordination with drillers to be used in coordination
with a DTH Hammer and simultaneously advance the drill string and
casing.
The Stratex eccentric bit design is rotated outward to drill a
larger diameter hole. Then the casing and overburden drill string
are advanced through the ground. Setting a cased hole in this way
helps to avoid cave-ins and wash outs. Once the required hole depth
is met, the reamer bit can be retracted by reversing the direction
of rotation and applying tension. Since the bit is eccentric the
outside diameter becomes smaller than the inside diameter of the
casing and this allows for easy removal of the pilot bit, reamer,
guide device and the rest of the overburden drill string.
Stratex Overburden Drilling Applications
The stratex overburden drilling system is used in the following
applications: drilling blast holes, casing water wells, setting
pilings and foundations for bridges and buildings, slant or
horizontal drilling, drilling air holes for mines, environmental
monitoring wells, grouting operations, seismic shot holes, soil
sample and geotechnical applications, ground anomaly and tiebacks.
The advantages of the Stratex overburden drilling system:
Low capital investment
High drilling performance
No rotation of the casing
Compatible with most drilling rigs
Virtually no casing stress
Casing is simultaneously lowered by the guide device and to deeper depths than other overburden drilling methods allow
Cost and on-site time reduced due to better penetration rates, easier bit changes, and stable hole conditions
Smaller pilot bit for faster and better penetration if compared to
other overburden drilling methods
