Customizable 12 1/4 PDC Bore Hole Opener Well Drilling Tool For Rock Formations
PDC Hole Opener for Wells Drilling
A hole opener is a device used to enlarge the borehole during a well drilling operation.
It can be positioned either above the drill bit or above a pilot run inside the existing borehole. Usages range from hydrocarbon drilling operations to water drilling or horizontal drilling.
Hole openers are also used when a hole must be logged, since logging tools generally cannot handle holes larger than 17 and a half inches in diameter.
Hole opener arms have to sustain heavy loads during operations and are generally made of high-grade alloy steel, welded onto a solid alloy steel body.
Some designs feature replaceable arms, allowing for size changes but decreasing overall robustness. Numerous designs exist, in sizes varying from a couple of inches to above 50".
They can have rolling cutters or drag blades, and can be used for either direct or reverse circulation applications.
