Abstract
Stuck-point calculation (SPC) is an important method to determine the stuck position of the drill string. It is of practical significance to explore and promote the SPC application in the field of mineral exploration. While Hooke's law is the foundation for the mathematical modeling, drill site conditions such as ground formation, borehole design and drilling process will be defining the factors and parameters in the formula. In recent years, the use of advanced full-hydraulic core drills provides a convenient means of on-site operation for stuck-point calculation. In this paper, the experimental operation at a deep-hole complex-formation drilling project in Yunnan Province, Southwest China, verifies that the SPC method is effective and conductive for mineral exploration core drilling activities.
