Factors Affecting The Construction Efficiency of Rotary Drilling RIGS

In modern construction, rotary drilling RIGS have become the main force in foundation construction due to their advantages of high efficiency and flexibility. However, its construction efficiency is not constant and is restricted by multiple factors. Understanding these key factors helps the construction team to implement precise policies and improve the project progress and economic benefits.

1. Geological conditions: The hardness of the stratum directly affects the drilling efficiency, and rock layers take more time than soil layers. Meanwhile, special geological conditions such as quicksand layers and silt layers are prone to cause hole collapse, increasing the procedures of hole cleaning and reinforcement, and significantly reducing the construction efficiency.

2. Equipment performance: Parameters such as the torque and drill pipe lifting force of the rotary drilling rig determine its rock breaking and soil excavation capabilities. Old equipment has insufficient power and is prone to stuck drilling and malfunctions. Frequent maintenance will disrupt the construction pace.

3. Drill bit selection: Different strata are suitable for different drill bits. For example, rotary buckets are used for soil layers and cone drill bits for rock layers. Choosing the wrong drill bit can lead to slow drilling and even severe wear, affecting normal construction.

4. Operator skills: Skilled operators can adjust drilling parameters in a timely manner according to geological changes and reasonably control the footage rate. Those with insufficient experience are prone to cause the drill bit to deviate or get stuck due to improper operation, thus delaying the project schedule.

5. Construction process: Unreasonable planning of the drilling sequence can lead to frequent displacement of machinery. Improper mud mix will affect the wall protection effect and increase the hole cleaning time, all of which will lower the overall construction efficiency.

6. External environment: Severe weather conditions such as high temperatures and heavy rain restrict equipment operation. Traffic congestion affects material transportation. Surrounding buildings or pipelines limit the position of drilling RIGS, all of which will have a negative impact on construction efficiency.

In conclusion, the construction efficiency of rotary drilling RIGS is influenced by a combination of various factors such as geology, equipment, human activities, and the environment. Only by fully considering these factors, scientifically planning the construction plan, improving the equipment maintenance level and strengthening the operational skills of personnel can the construction efficiency of the rotary drilling rig be maximized and the efficient progress of the project be guaranteed.
