Precautions for Rotary Drilling Rig Operations in Desert Areas

Desert environments pose unique challenges for rotary drilling rig operations due to high temperatures, dryness, strong winds, and specific geological conditions. These factors can affect construction efficiency and pose risks to equipment and personnel. Therefore, scientific measures must be adopted to address environmental issues and ensure smooth and safe construction. Below are key aspects to consider when operating rotary drilling rigs in desert conditions.

1. Equipment Management and Protection

1. Preventing Overheating
   High temperatures in desert regions can cause the hydraulic system and engine of the drilling rig to overheat, reducing efficiency or leading to malfunctions. Before construction, ensure the cooling system is in good condition, and if necessary, increase the coolant volume. During construction, adopt a work-rest cycle to allow adequate cooling time for the equipment.

2. Dust Prevention
   Dust is a major issue in desert construction, potentially entering the equipment and causing wear or malfunctions. Key components like the engine, hydraulic system, and filters should be sealed and regularly cleaned to prevent damage from sand accumulation.

3. Lubrication Maintenance
   The dry desert environment accelerates the evaporation of lubricants, reducing their effectiveness. Use high-performance, heat-resistant lubricants and increase replacement frequency based on operating conditions to ensure smooth equipment performance.

2. Construction Techniques

1. Geological Assessment
   Desert geological conditions vary, ranging from loose sand to hard rock layers. Conduct detailed geological surveys before construction to formulate appropriate drilling plans, ensuring stability and load-bearing capacity of the foundation.

2. Adjusting Drilling Techniques
   In loose sand layers, control drilling speed to prevent hole collapse. Use drilling tools suitable for sand layers, such as spiral or short augers, to enhance debris removal efficiency. During concrete pouring, maintain a quick and continuous process to prevent water absorption by sandy soil.

3. Dust Control
   Dust generated during drilling affects efficiency and poses health risks to workers. Use water spraying devices or dust suppressants to minimize dust and maintain air quality in the work area.

3. Worker Management and Safety

1. Heat Protection
   High temperatures can cause heatstroke. Workers should wear breathable clothing, protective hats, and goggles. Set up shaded areas and provide cool drinks on-site, ensuring sufficient rest periods to avoid prolonged exposure to heat.

2. Safety Training
   The unique desert environment requires workers to have relevant safety knowledge, including responding to sandstorms and high-temperature operations. Provide specialized training before construction to improve emergency response capabilities.

4. Managing External Factors

1. Sandstorm Protection
   Sandstorms are common in deserts. Stop work immediately if one occurs, park equipment in sheltered areas, and cover it to minimize dust damage. Workers should evacuate to safe zones equipped with protective gear.

2. Road Maintenance
   Transportation in desert areas can be challenging due to wind erosion. Construct temporary access roads to the site and maintain them regularly to ensure smooth transportation of materials and equipment.

5. Resource Management and Emergency Preparedness

1. Efficient Water Use
   Water is scarce in deserts, but it is essential for dust suppression and concrete mixing. Develop a scientific water use plan to optimize available resources and consider long-distance water supply solutions.

2. Emergency Plans
   Prepare detailed emergency plans for potential risks such as equipment failure, heatstroke, and sandstorms. Conduct drills to ensure quick responses and minimize losses or delays during emergencies.
