Overburden Drilling ODEX240 ODEX Casing Tube Systems For 8" Hammer
Product Specification:
ODEX system Eccentric Casing system is suitable for drilling
water wells, geothermal wells, short mircopiles,medium mini-type
grouting hole of building,damand harbour project.
- Rapid removal of cuttings; High penetration rate, especially in
resistant rock formation;
- Easy soil and groundwater sampling during drilling;
- Possible to measure yield estimate at selected depth in the
formation;
- Advantageous in unconsolidated formations with a high risk of
caving
Casing drilling involves drilling and casing a well simultaneously
through unstable ground conditions, In casing drilling process,
down the hole tools can be retrieved, through the casing on
wire-line, meaning tool recovery or replacement of tools
can take minutes versus hours under conventional methods. This
process employs wire line-retrievable tools and a drill-lock
assembly, permitting bit and BHA changes, coring, electrical
logging and even directional or horizontal drilling. Once the
casing point is reached, the casing is
cemented in place without tripping pipe.
Casing drilling has been employed in many countries as an effective
method of reducing the overall drilling costs by reducing drilling
time and drill string problems
encountered during conventional drilling process.
