XCMG horizontal directional drill rig holds an very imortant position in China. XCMG (Xuzhou Construction Machinery Group) has a remarkable history in the non-excavation industry. In 2002, XCMG developed China’s first domestically produced horizontal directional drilling rig, the ZD1245, breaking the monopoly of imported equipment in the high-end market10. This marked the beginning of XCMG’s

We all know there are 3 roller cones in a tricone drill bit, and that is also the reason they are named “tricone”. But are these three roller cones total same? Which one is cone number 1, 2 or 3? Let’s discuss it as follows. Number the roller cones in a tricone drill bit from

Vermeer directional drill is an important player in this industry. Founded in 1948 by Gary Vermeer, the company started in a small Iowa town. It initially produced agricultural machinery. Today, Vermeer specializes in trenchless technology and horizontal directional drilling (HDD) equipment. Brief message of Vermeer company The company operates globally with manufacturing facilities in the U.S.

Tri-cone drill bits with metal-sealed bearing structure are broadly used in very tough or complicated formations. Compared with rubber-sealed structure, a metal-sealed tricone bit bears heavier W.O.B. and survives longer in different conditions. On the other hand, better performance means higher price. Metal-sealed tri-cone drill bits are generally 30% more expensive than rubber-sealed ones. This

Power or motor section A drilling mud motor has three main parts: the housing, a steel stator, and an elastomeric rotator. Essentially, it operates as a reverse Moineau pump. Drilling fluid is pumped into the motor’s progressive cavities. As the fluid moves, it forces the shaft to rotate inside the stator. In short, the power

1. Roller-bearing systems VS Journal-bearing systems Roller-bearing systems Roller bearings are widely used in bit-bearing systems. They handle heavy loads effectively and perform well in drilling conditions (Figure. 1). These bearings are commonly found in larger-diameter bits (> 14 in.), as they require more space for the rollers. To improve durability, manufacturers focus on advancing

Foreword Understanding IADC codes makes choosing the right drill bit much simpler. Whether you’re picking a Tricone or a PDC bit, paying attention to the small details is key. Make smart choices to keep your drilling operations running smoothly and achieve success with precision. This guide includes diagrams, charts, and real-world examples to help you
