Application Scenarios of Water Well Drilling Rigs

Core Application Scenarios

1. Agriculture and rural water supply
Application characteristics: To solve the demand for farmland irrigation and rural domestic water in arid areas, it is necessary to penetrate different geological layers, such as soft soil layer, gravel layer, etc.
Equipment requirements: The drilling rig needs to have efficient drilling ability and stability to ensure rapid well completion under complex geological conditions.
Typical case: In arid areas, farmers use water well drilling rigs to dig deep wells to ensure the amount of water needed during the growing season of crops and reduce their dependence on natural precipitation.

2. Urban water supply and emergency rescue
Application characteristics: When the water quality of the old urban community is declining due to the aging of the pipeline, the construction of new wells needs to be completed quickly; When traditional water sources are polluted after floods, emergency water supply wells need to be built urgently.
Equipment requirements: The rig needs to be responsive and modular, making it easy to transport and deploy.
Typical case: In a typhoon-stricken area, three portable drilling rigs worked together to build an emergency water supply well within 12 hours, providing clean water to 2,000 affected people.

3. Industry and energy development
Application characteristics: chemical plants need a large amount of cooling water to maintain the operation of the equipment, and need to accurately reach the aquifer; Oil extractors need to drill wells around the oil fields to monitor changes in the groundwater level.
Equipment requirements: The drilling rig needs to be equipped with directional drilling technology and core sampling device to facilitate the analysis of formation structure.
Typical case: A chemical plant uses drilling rig directional drilling technology to accurately reach the aquifer and pump industrial water that meets the standards.

4. Geological disaster early warning and ecological restoration
Application features: Arrange monitoring wells in landslide-prone areas to collect groundwater level and soil moisture data in real time; In desertification control areas, network well groups are built to replenish underground aquifers.
Equipment requirements: The drilling rig needs to have high-precision hole direction control and the ability to adapt to complex geology.
Typical case: In a mountainous area, a drilling rig penetrated the loose soil layer and installed sensors to predict debris flows 48 hours in advance, successfully avoiding major casualties.

The Key Points of Equipment Selection

1. Geological adaptability
According to the geotechnical investigation report of the target area, the matching drilling process is selected. For example, in complex geology such as pebble layer and permafrost layer, percussion drilling rig has strong penetration; In loose formations, gravel formations and some soft rock formations, rotary drilling rigs are more efficient.

2. Drilling efficiency and cost
Take into account equipment costs, energy consumption levels, and maintenance complexity. For example, the maintenance cost of an electric motor is 40% lower than that of a diesel model, but grid coverage needs to be evaluated.

3. Life cycle cost
In addition to the initial purchase cost, the service life of the equipment, maintenance costs, and energy consumption need to be considered. For example, although the initial investment of hydraulic power head drilling rigs is higher, the long-term cost of use may be lower due to their high efficiency and energy saving.

Operation and Maintenance Specifications

1. Installation and commissioning
Ensure that the specifications of the drill cavern meet the requirements, the pillars are firmly fixed to the ground, and the water and oil pipelines and lighting fixtures are connected to the vicinity of the excavation face for later use.
Before starting, it is necessary to comprehensively check whether the water and oil pipeline connection is firm, and whether the screws, screw caps, and connectors of each part of the drilling rig are tightened.

2. Operational specifications
After starting the motor to ensure the normal operation of all parts of the equipment, adjust the handle of the impactor to the working position and start the drilling operation.
During the drilling process, the inlet valve needs to be opened to ensure that the gas-liquid mixture is maintained in the proper proportion, improving drilling efficiency and reducing equipment wear.

3. Maintenance and maintenance
Regularly inspect the wearing parts of the drilling rig, such as sealing rings, filter elements, etc., and replace them in time according to the use of the equipment.
Regularly check the quantity and quality of the lubricating oil to ensure that the lubrication system is working properly.
When the rig is not in use, store the equipment in a dry, well-ventilated environment away from moisture or sunlight.

Industry Trends

1. Intelligence and automation
Equipped with Internet of Things sensors, real-time monitoring of drilling pressure, torque, speed and other parameters can be realized, and the accuracy of fault warning is improved.
Relying on the Beidou positioning system, the unmanned drilling rig can independently complete the well construction at night to improve the operation efficiency and safety.

2. Environmental protection and energy saving
The double-pump hydraulic system is more energy-efficient than the single-pump solution, and the mud zero-discharge treatment device reduces drilling fluid pollution.
The air circulation drilling technology avoids mud contamination and ensures that the effluent is directly drinkable.

3. Multi-function and customization
According to different geological conditions and engineering needs, we develop multi-functional water well drilling rigs and provide customized operation solutions.
For example, in archaeological excavations, micro-borehole drilling rigs are used to explore the extent of the site without destroying the cultural layer.
