案例分享 DualHelix Bit Boosts Drilling Performance in Shale Play
DualHelix bit delivers superior drilling performance and excellent toolface control in Haynesville Basin.
DualHelix
Multiformation performance bit
Overview
Optimize cutting efficiency
Our DualHelix™ multiformation performance bit leverages cutter placement geometry to adapt cutter engagement based on the depth of cut. This bit is more than connected blades with opposite helix direction. Its patented design details ensure ultimate performance in both soft and hard formations. By strategically positioning cutters with variable curvature along the bottom hole pattern, the wake created by the leading cutters optimizes cutting efficiency.
This passive engagement method operates without any moving parts, relying solely on the three-dimensional sweep resulting from shearing rock removal. The bit's body and blade shape offer hydraulic advantages that enhance bit cleaning and cutter cooling in response to cutter loading. Additionally, the bit can be combined with SLB cutter technologies.
