How Does The YG Deep Well Drilling Machine Work? 7 Process
Step 1: Site Preparation & Machine Setup
First, conduct a geological survey to determine the drilling location and target water depth (avoiding rocky areas or underground pipelines). Clear the site of obstacles, level the ground, and ensure the machine is placed on a stable surface. For a crawler deep-well drilling machine, adjust the track tension; for wheeled models, fix the support legs to prevent tipping. Assemble the drill mast, drill pipe and drill bit according to the geological conditions—use alloy bits for hard rock and diamond bits for extra-hard formations.
Step 2: Pre-Drilling Inspection
Check the diesel engine oil, hydraulic oil and coolant levels; ensure no leaks. Test the hydraulic system, drill rotation, and lifting functions to confirm they are flexible and responsive. Prepare drilling auxiliary materials (drilling mud, casing pipes) to stabilize the borehole wall and prevent collapse during drilling.
Step 3: Drilling Commencement
Start the diesel engine, adjust the drilling speed and pressure according to the stratum. The hydraulic system drives the drill bit to rotate and drill downward slowly. For loose soil or clay, use low speed and moderate pressure; for hard rock, increase the pressure and switch to high-speed rotary drilling. During drilling, continuously add drilling mud to the borehole—this mud cools the drill bit, carries away rock debris and stabilizes the borehole wall.
Step 4: Drill Rod Extension
As drilling progresses and the borehole deepens, stop the machine periodically to add drill rods. Connect the new drill rod to the existing one with a coupling, ensure the connection is firm, then resume drilling. Repeat this step until the drill reaches the target water-bearing stratum (detected by the water level sensor on the machine).
Step 5: Casing Installation
After reaching the water-bearing stratum, stop drilling and install casing pipes into the borehole to prevent the borehole wall from collapsing and to keep the well clean. The casing pipes are connected section by section and lowered to the bottom of the borehole, with the gap between the casing and the borehole wall filled with cement to fix the casing.
Step 6: Well Flushing & Water Testing
Use a high-pressure pump to flush the well with clean water, removing rock debris and drilling mud from the borehole until the water becomes clear. Then conduct a water yield test to check if the well’s water output meets the demand (YG machines are equipped with flow meters for accurate measurement). If the water yield is insufficient, continue drilling deeper or adjust the drilling location.
Step 7: Well Completion & Machine Shutdown
After the water yield test is qualified, install a well screen at the bottom of the casing to filter sand and impurities, then install a water pump to extract water. Clean the YG deep well drilling machine, remove the drill pipe and drill bit, and clean the mud and debris from the machine. Lower the drill mast, turn off the engine, and transport the machine to a safe storage area.
Where YG Deep Well Drilling Machine Applications? 7 Usages
1. Rural Domestic Water Supply
This is the most common application of the YG deep well drilling machine. In remote rural areas without tap water, deep wells provide access to clean underground water, solving the drinking water problem for rural households. The machine can adapt to various rural terrains (plains, hills, mountains) and drill wells with stable water output.
2. Agricultural Irrigation
For farms, greenhouses and large farmland, the water well drilling machine for sale drills irrigation wells to provide a stable water source for crops. YG’s deep-well drilling equipment can drill wells with large water yields, suitable for large-scale irrigation of grain, vegetables and fruit trees. It helps farmers reduce dependence on natural rainfall and improve crop yields, especially in arid and semi-arid regions.
3. Industrial Water Supply
Factories, mining sites, power plants, and other industrial enterprises need a large amount of water for production and cooling. The yg deep well drilling machine drills deep industrial wells (180m–600m) to provide high-quality underground water, which is more cost-effective than tap water. It is widely used in mining, chemical, textile, and food processing industries, ensuring a continuous production water supply.
4. Municipal Emergency Water Supply
In cities facing water shortages, natural disasters (floods, droughts), or tap water pipe maintenance, the well drilling equipment for sale is used to drill emergency water wells quickly. YG’s crawler deep-well drilling equipment can be transported to disaster areas and complex terrain, drilling wells in 1–3 days to provide emergency water for residents and rescue teams, playing a crucial role in disaster relief.
5. Geothermal Well Drilling
The deep well drilling machine is also used for geothermal well drilling to extract geothermal energy for heating, bathing, and greenhouse cultivation. It can penetrate hard rock formations to reach geothermal reservoirs, and the stable drilling performance ensures the smooth progress of geothermal projects. This application is popular in countries with rich geothermal resources, such as Iceland, New Zealand, and so on.
6. Mountainous Area Water Resource Development
Mountainous areas have complex terrain and scarce surface water, making it difficult to access drinking water. YG’s crawler deep-well drilling equipment can climb slopes (≤30°) and work in narrow mountainous areas, drilling wells to access underground water. It has been widely used in mountainous regions of Africa, South America, and Southeast Asia, improving the living conditions of mountain residents.
7. Livestock Breeding Water Supply
Large-scale livestock farms (cattle, sheep, poultry) need a large amount of clean water for animal drinking and pen cleaning. The water well drilling machine for sale drills special water wells for farms, providing sufficient clean water to ensure the health of livestock and improve breeding efficiency. It is suitable for large-scale breeding bases in rural and suburban areas.
