Brief Introduction of Horizontal Directional Drilling System
The horizontal directional drilling rigs of various specifications are composed of drilling rig system, power system, steering system, mud system, drilling tools and auxiliary tools. Their structure and functions are introduced as follows:
3.1 Drilling rig system: It is the main body of the drilling operation and the towing operation through the equipment. It consists of the drilling rig main unit, turntable, etc. The drilling rig main unit is placed on the drilling frame to complete the drilling operation and the towing operation. The turntable is installed at the front end of the main rig of the rig, connected to the drill rod, and by changing the turntable steering and output speed and torque, to meet the requirements of different operating conditions.
3.2 Power system: The power source is composed of a hydraulic power source and a generator. The power source is to provide high-pressure hydraulic oil for the rig system as the power of the rig. The generator provides power for the supporting electrical equipment and construction site lighting.
3.3 Direction control system: The direction control system is a directional tool that monitors and controls the specific position of the drill bit underground and other parameters to guide the drill to drill correctly. Due to the control of the system, the drill can drill according to the design curve There are two types of steering systems, portable wireless and wired, that are often used.
3.4 Mud system: The mud system is composed of a mud mixing tank, a mud pump and a mud pipeline to provide mud suitable for drilling conditions for the rig system.
3.5 Drilling tools and auxiliary tools: all kinds of tools used when drilling and reaming during drilling. Drilling tools mainly include drill rods, drill bits, mud motors, reamers, cutting knives and other tools suitable for various geology. Auxiliary tools include snap rings, swivel unions, and drag heads of various pipe diameters.
