Eccentric Casing Drilling System may be utilized with any DTH drill rig, any size casing, and is particularly helpful with thin wall casing. For drilling in challenging ground conditions, Casing Drilling System is the preferable technique. When drilling and casing are done simultaneously, there is a lower chance of the hole collapsing and you can work more quickly and effectively. Casing Drilling System is also the most cost-effective option due to the inventive reaming wing's retrievable bit that can be used for the next hole.The technology is specifically created to provide the highest level of dependability under overburdened drilling circumstances. By using this technology, it is possible to drive the casing in any downward vertical direction or formation while preventing equipment loss and collapsing holes.
This is a two-piece bit made up of an eccentric reamer that swings out and enlarges the hole's diameter before forcing the casing down into it. After the reamer has been retracted to the desired depth, the entire system is taken out and utilized once more, leaving the case in place for other applications. technology is used globally in a variety of ground drilling applications, including dam and port construction, micro piling, water well drilling, and geothermal drilling.
