PDC cutters different features are selected and bit profile design is optimized to suit different drilling applications in different formations to satisfy different requirements when drilling soft to medium hard formations without sulfureted hydrogen well section.
Cutting structure is force balanced,non-symmetrical blade and deep junk slots are designed to dramatically improve ROP of the bit.Matrix material of the bit adopts high quality steel and wear-resistance material with high performance is build-up welded on the surface of blades to prevent material from eroding.
Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.
Machining precision and retention of cutters are ensured by using milling center with high performance five axes and high speed milling technology.
Hole Openers are used to enlarge the diameter of a pre-drilled hole. They are custom built to specification, and come in a wide variety of sizes. A Hole Opener is sometimes referred to as a Reamer.
Roller cone hole openers are specifically designed for horizontal, rock drilling applications. Extensive tool performance experience combined with the pooling of hole opener expertise from various industries (directional crossing, mining and oil field) has aided in designing and manufacturing a proven line of horizontal hole openers for the trenchless construction industry. Our approach to tool application analysis and tool set-up recommendations includes cutting structure selection, hydraulics and torque and drag analysis. This comprehensive approach enables us and the contractor to minimize the number of reaming passes and optimize hole opener performance.
