Problems Affecting The Construction Efficiency of Rotary Drilling RIGS

The construction efficiency of rotary drilling RIGS is directly related to the project progress and cost control, and various factors during construction may affect its efficiency. Understanding and avoiding these problems can effectively accelerate the construction pace and ensure that the project proceeds as planned.

1. Complex geological conditions: When encountering special geological conditions such as hard rock and quicksand, the drilling resistance of the drilling rig increases, and situations such as stuck pipe and hole collapse are prone to occur. It is necessary to conduct geological surveys in advance, select suitable drill bits and adjust drilling parameters.

2. Insufficient equipment maintenance: Problems such as worn drill bits not being replaced in time and lack of oil in the hydraulic system can lead to a decrease in the power of the drilling rig and operational stuttering. Regular inspection of core components, proper lubrication and replacement of wear parts can reduce malfunctions.

3. Improper selection of drilling tools: Different strata require corresponding drill bits. For example, helical drill bits are used in clay strata, and cone drill bits are used in rock strata. If the drilling tool does not match the geological conditions, slow drilling or even damage to the drill bit may occur.

4. Differences in operational skills: Improper control of drilling speed and pressure application by operators can easily lead to ineffective operations such as empty drilling and over-digging. Skilled operation can make timely adjustments based on formation feedback, reducing ineffective working hours.

5. Auxiliary equipment coordination: Insufficient slurry supply from the mud circulation system and untimely removal of construction waste can force the drilling rig to shut down and wait. It is necessary to ensure that the auxiliary equipment matches the operation rhythm of the drilling rig to form a continuous process.

6. On-site management issues: Unreasonable planning of the construction site and frequent relocation of drilling RIGS; The materials are piled up in a disorderly manner, increasing the time it takes to retrieve them. Reasonable site planning and clear division of labor can reduce non-operational time consumption.

To sum up, the issues affecting the construction efficiency of rotary drilling RIGS involve multiple aspects such as geology, equipment, operation, and management. Through advance investigation, standardized operation, proper maintenance and optimized management, these problems can be effectively solved, enabling the rotary drilling rig to achieve maximum efficiency and promoting the efficient progress of the project.
