High definition Down Hole Drill Pipe - Eccentric casing system /ODEX system – Spark
High definition Down Hole Drill Pipe - Eccentric casing system /ODEX system – Spark Detail:
Structure of Eccentric casing system /ODEX system
Structure features
The structure of the reamer is improved from figure(a) to figure(b), which strength the wearing resistance on the back, and extend the the service life of the whole reamer.
Working procedure
Step1: When drilling starts, the system drives the casing shoe and casing tube move down.
Step2: When reaching the bedrock, lift up the block system, the blocks will closed, reverse rotation and pull out the block system from the hole.
Step3: If the hole have reach the desired depth, finish the drilling and continue other process.
Step4: If you still want to drill deeper, use the conventional DTH bit to drill to the desired depth.
Applications
Water well drilling
Eccentric system is the main drilling tool in water well projects, which can keep drilling the hole and protecting it from caing at the same time, and it can significantly reduce the drilling time when drilling through the overburden.
Micro piling
In soil, clay and sand rock formation, eccentric system is the most economic and fastest in protecting the hole from collapsing with permanent temporary casing tubes.
Anchoring
Eccentric system can meet the requirements of anchoring projects better when reinforcing the slope.
