Introduction to Horizontal Directional Drilling System

1. Drilling system: it is the main body of the drilling operation and pull back operation of the crossing equipment. It consists of the main machine of the drilling machine, rotary table, etc. The main machine of the drilling machine is placed on the drilling rig to complete the drilling operation and pull back operation. The rotary table is installed at the front end of the main machine of the drilling rig to connect the drill pipe, and the requirements of different operating conditions are met by changing the rotary table steering and output speed and torque.
2 Power system: The power source consists of hydraulic power source and generator, which provides high pressure hydraulic oil for the drilling system as the power of the drilling rig, and the generator provides power for the supporting electrical equipment and construction site lighting.
3 Direction control system: The direction control system is a directional tool that guides the correct drilling of the drill bit by monitoring and controlling the specific position and other parameters of the drill bit underground through the computer. Because of the control of the system, the drill bit can be drilled according to the design curve. Currently, there are two types 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 system with mud suitable for drilling conditions.
5 Drilling tools and auxiliary machines and tools: various machines and tools used in drilling and reaming. Drilling tools are mainly suitable for various geological conditions
