The operation records of second-hand rotary drilling RIGS are not merely "running accounts", but rather the core basis for equipment condition monitoring, maintenance planning and construction efficiency optimization. By standardizing records and applying them reasonably, not only can fault risks be Read More

In the construction of second-hand rotary drilling RIGS, the verticality of the borehole directly affects the project quality, and this requires a close coordination between the performance of the accessories and the operation specifications. The following breaks down specific guarantee methods from Read More

The hydraulic system is the "power core" of second-hand rotary drilling RIGS. Excessively high pressure can easily lead to pipeline burst and component wear, while excessively low pressure will affect drilling efficiency and even cause equipment failure. Scientifically adjusting the pressure of the Read More

In the construction of rotary drilling RIGS, the drill bit is the core component. The drill bits of second-hand rotary drilling RIGS, due to their longer usage time, are more prone to wear and tear. If new drill bits are directly replaced, the cost will increase. However, reasonably repairing and re Read More

Due to long-term use, second-hand drill pipes are prone to wear and deformation at the joints. If the butt connection operation is not standardized, it will not only accelerate the wear of the drill pipe but also affect the verticality and depth accuracy of the borehole. Mastering scientific docking Read More
