What Pressure Method Is Better for Rotary Drilling Rig

In construction, the pressure mode of rotary drilling rig has a key influence on construction efficiency and quality. Different pressure methods have advantages and disadvantages, which is better? Here is a detailed introduction for you.

1. Hydraulic pressure: rely on the hydraulic system to produce pressure, strong and stable power. It can adapt to a variety of complex geology, effectively improve drilling speed, and is widely used in various large-scale projects.

2. Lifting pressure: the lifting machine is used to bring down the steel rope to achieve pressure. The structure is relatively simple, the cost is low, but the precision of pressure control is slightly inferior.

3. Self-weight pressurization: use the weight of the rig to pressurize. It is easy to operate, but its pressurization effect is limited in hard formations.

4. Compound pressure: Combine a variety of pressure methods to give play to their respective advantages. It can be flexibly switched according to different geological conditions to improve the overall construction performance.

5. Mechanical pressure: The use of mechanical transmission structure pressure, high precision. However, the mechanical parts are easy to wear, and the later maintenance cost is relatively high.

6. Air pressure: compressed air as the power source, clean and environmentally friendly. However, the output pressure is relatively small, and it is generally suitable for small drilling RIGS or softer formations.

Conclusion: The selection of pressure mode of rotary drilling rig should consider many factors such as geological condition, project scale and cost budget. There is no absolute best way to pressurize, only the choice that best suits the specific needs of the project, so as to ensure that the construction is efficient and smooth.
