1. Overview
The 400 meter water well drilling rig is a high-performance and efficient drilling equipment. It adopts advanced hydraulic system and drill string, which can quickly and accurately complete drilling operations. This equipment is easy to operate, stable in operation, and has a certain degree of risk resistance, suitable for drilling operations under various geological conditions.
Fast drilling speed and high torque, the drilling speed of the drilling rig can reach the maximum output torque:
Strong power and improved efficiency. The drilling rig adopts a long stroke double speed mechanism and a mechanical power head with a power stroke of 400mm, which is used to improve drilling efficiency, reduce drilling blockage and burning accidents
Less loss and fuel consumption, the drilling rig uses dual oil pumps for fuel supply, and a single pump is used for merging during drilling, resulting in less power loss and shorter auxiliary time.
Hydraulic support legs: reinforced support legs for better support
２.Maintenance cycle summary table

３.Economic benefits based on the situation in China
① Cost control
Mechanized drilling reduces comprehensive costs by 52% -68% compared to traditional manual labor (according to the World Bank's 2023 Groundwater Project Report)
Diesel powered drilling rig has a drilling cost of 50-80 yuan per meter, and the electric motor type can be further reduced to 35-60 yuan
Modular design reduces maintenance costs by 40% and reduces the time required for replacing vulnerable parts by 75%
② Investment return
Medium sized drilling rigs (such as SPC-300T) have a payback period of approximately 8-14 months under a daily operating condition of 10 hours
The lifespan of the core components of the drilling rig has exceeded 12000 hours, and the entire lifecycle can complete 600-800 standard water wells (with a depth of 80m)
The cost of transferring vehicle mounted drilling rigs has been reduced by 90%, and the transfer time has been reduced from 6-8 hours for traditional equipment to within 1.5 hours
③ Resource conservation
Intelligent speed control system reduces fuel/electricity consumption by 25% -30%
The circulating mud system increases water resource utilization by 300%
Precision drilling technology reduces ineffective rock fragmentation losses by 15% -20%
