Horizontal directional drilling rig system configuration

Horizontal directional drilling rigs of various specifications are composed of drilling system, power system, steering system, mud system, drilling tools and auxiliary tools. Its structure and function are described as follows:

1 Drilling rig system: it is the main body of drilling operation and backdragging operation of crossing equipment. It is composed of drilling rig host, turntable, etc. The main rig is placed on the rig frame to complete drilling and towing operations. The rotary table is installed at the front end of the main machine of the drilling rig and connected with the drill pipe. By changing the turntable steering, output speed and torque, it can meet the requirements of different working conditions.

2 power system: 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. 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 location of the drill bit underground and other parameters through a computer to guide the drill bit to drill correctly. Due to the control of the system, the drill bit can drill holes according to the design curve. There are two types of direction control systems that are often used today: portable wireless and wired.

4 Mud system: The mud system consists of mud mixing tank, mud pump and mud pipeline to provide mud suitable for drilling conditions for the drilling rig system.

5 drilling tools and auxiliary tools: drilling rig for drilling, reaming of various tools. Drilling tools mainly include drill pipe, drill bit, mud motor, reamer, cutter and other equipment suitable for various geological conditions. Auxiliary equipment includes snap rings, swivel joints and pull heads for various pipe diameters.
