Basic Requirements Of Water Well Drilling Tools

Compared with water wells, Water Well Drilling Tools is very large. In order to facilitate assembly and disassembly before and after drilling, thereby shortening the construction period

Compared with water wells, Water Well Drilling Tools is very large. In order to facilitate assembly and disassembly before and after drilling, thereby shortening the construction period, the parts of the drilling rig for drilling, such as rigs, platforms, etc., must be integrated with light weight.


  1. Use the right drill
    During the drilling process, the corresponding tri-cone bit should be used to prevent the cone from falling into the well and causing irreparable losses. Geothermal wells are drilled very deep. As the depth of the hole increases, the temperature rises and the underground conditions are complex and changeable. Therefore, a good quality tri-cone drill bit must be selected to ensure safe operation.
    2. The capacity of the hoist should be large, and the automatic drilling device can increase the speed
    Geothermal drilling is usually large-diameter drilling, and most of the geological formations drilled are hard, broken, and high-temperature rocks. During the drilling process, the load and rotation of the drill bit are important factors that affect the drilling. Therefore, the capacity of the hoist must be strong and equipped with an automatic drilling device to increase the drilling speed and save electricity.
    Three, must be equipped with a large displacement mud pump.
    During the drilling process, the circulating mud will be heated to the boiling point soon after it contacts the high-temperature formation. If it is not treated, there is a danger of gushing. At the same time, high temperature has a great impact on the drill bit, and the performance of the mud itself is also changing, which is easy to cause hole wall collapse. Therefore, Geothermal Energy reminds you that before drilling, you must be equipped with a large displacement mud pump that matches the mud cooling device to safely control the temperature in the well and try to avoid the danger of hole wall collapse.
    Fourth, use a blowout preventer to deal with hot water and steam
    Blowout prevention devices are indispensable because the geothermal wells undergo drastic changes during drilling. When drilling into high-pressure steam and water layers, the excessive pressure and the intrusion of mud will cause the density of the mud to decrease rapidly. Make hot water or hot steam gush, and the blowout preventer is a heat-resistant protective device, which is helpful to quickly stop the gush of hot water and steam.
    5. Monitoring equipment in geothermal wells
    The geological conditions of the drilling at Rock Button Bits combined with the underground hot water reserves are usually complicated. During the drilling process, the geothermal energy adopts corresponding real-time monitoring equipment to timely analyze possible accidents during the drilling process and analyze the holes. If an abnormal situation is found in the well, it will be dealt with in time to avoid drilling accidents and maximize the benefits of the development and utilization of geothermal resources.
