Because of its simple structure, diamond drill bits have high strength, high wear resistance and impact resistance. It was in the 1980s.One of the three new drilling technologies in the world. Field use proves that diamond bits have speed when drilling in soft-medium hard formations.Fast, more footage, long life, stable work, fewer downhole accidents, good well quality and so on. Carbide tungsten steel nozzle.As one of the important parts in the diamond drill bit, it has the cleaning effect on the drill bit and the bottom of the well and the hydraulic rock breaking effect of the nozzle.Conventional nozzles are cylindrical and can produce a balanced pressure distribution on the rock surface.
In drilling operations, inhibiting the formation and development of bit mud packs is very important to improve drilling speed and ensure drilling safety. PDC Bit directional nozzle is a type of jet nozzle with one or more side holes. It is installed on the PDC bit, and the drill is cleaned by multiple jets.Head to minimize the generation of mud packs and cool the cutting teeth.
Fast speed, more footage, long life, stable work, fewer downhole accidents, good wellbore quality, etc.
