SPC-300ST钻机与全液压车载动力头钻机在马里钻井中的应用比较OA

In the 1980 s,Chinese geological survey companies entered the African drilling market with government economic aid projects.These companies quickly seized the African water well market with their complete water well drilling equipment and advanced water well drilling technology.The SPC-300 series hydrological water well drill produced by Tianjin Exploration Machinery Factory played an indispensable role.After entering the 21st century,the fully hydraulic truck-mounted power head drill produced in India began to enter African market and has become the main drilling equipment in local area.Through practical application comparison,the following conclusions are drawn:① The traditional truck-mounted rotary table SPC-300ST drill has significant advantages in terms of lifting capacity,torque,drilling depth,mud pump performance,drilling speed and formation adaptability;② The fully hydraulic truck-mounted power head drill has outstanding performance in integration,intelligence,automation and air compressor performance,which can reduce operational difficulty,improve construction accuracy,and reduce equipment and personnel configuration;③According to the hydrogeological conditions and water well drilling requirements in Mali,fully hydraulic drills are more suitable for actual working conditions;④ In the future,truck-mounted water well drills should be developed in integration,automation and intelligence.By optimizing equipment structure and regional adaptability,economic benefits can be improved while reducing investment costs.
