This invention discloses a double-helix composite blade long-diameter-maintaining coring drill bit and its manufacturing method, belonging to the field of geological drilling coring equipment. The drill bit includes a drill bit steel body, double-helix composite blades, and a coring inner cylinder. The double-helix composite blades are arranged in a double-helix staggered distribution, including polycrystalline diamond cutting blades and surface-impregnated diamond grinding blades. The polycrystalline diamond cutting blades have a three-dimensional helical forward-inclined structure, embedded with frustum-shaped polycrystalline diamond sheets and triangular polycrystalline diamonds. The surface-impregnated diamond grinding blades have an axial helical structure, equipped with low-temperature surface-impregnated matrix blocks and surface-impregnated large diamond particles. The outer wall surface of the blades is equipped with a helical long-diameter-maintaining structure. The manufacturing method integrates three processes: pressureless impregnation, hot-pressing sintering, and brazing, to prepare the blade matrix base and the surface-impregnated matrix blocks respectively, and then weld them into shape. This invention, through optimized structural design and multi-process synergy, significantly improves the coring efficiency, wear resistance, and structural stability of the drill bit in complex formations, achieving long-term diameter maintenance and high-efficiency drilling.
