Do You Know What Constitutes The Horizontal Directional Drilling System?

With the progress of the times, modern crossing equipment has high crossing accuracy, and horizontal directional drilling rigs of various specifications have emerged. The horizontal directional drilling technology is a new construction technology that combines the directional drilling technology of the petroleum industry with the traditional pipeline construction method. It has the advantages of fast construction speed, high construction accuracy and low cost. It is widely used in the pipeline laying construction projects of water supply, gas, electricity, telecommunications, natural gas, oil and so on. What are the horizontal directional drilling system? And what is their structure and function? Xiaobian will introduce it to you.

Horizontal directional drilling is a new production technology, which is composed of drilling system, power system, directional control system, mud system, drilling tools and auxiliary machines and tools. Their structures and functions are introduced as follows:

1) Drilling rig system: it is the main body of drilling operation and back dragging operation of crossing equipment. It is composed of drilling rig host, rotary table, etc. the drilling rig host is placed on the drilling rig frame to complete drilling operation and back dragging operation. The rotary table is installed at the front end of the main machine of the drilling rig, connected with the drill pipe, and meets the requirements of different operation states by changing the steering and output speed and torque of the rotary table.

2) Power system: it is composed of hydraulic power source and generator. The power source is to provide high-pressure hydraulic oil for the drilling rig system as the power of the drilling rig, and the generator provides power for supporting electrical equipment and construction site lighting.

3) Direction control system: the direction control system is a directional tool that monitors and controls the specific position and other parameters of the drill bit underground through the computer, and guides the drill bit to drill correctly. Due to the control of this system, the drill bit can drill according to the design curve. At present, there are two forms of direction control systems, portable wireless and wired.

4) Mud system: the mud system is composed of mud mixing tank, mud pump and mud pipeline to provide the drilling rig system with mud suitable for drilling conditions.

5) Drilling tools and auxiliary machines and tools: they are all kinds of machines and tools used in drilling and reaming. Drilling tools mainly include drill pipes, drill bits, mud motors, reamers, cutting knives and other machines and tools suitable for various geological conditions. Auxiliary machines and tools include snap rings, rotary unions and pullers with various pipe diameters.
