Different core analysis methods affect exploration accuracy to varying degrees. Traditional methods, like visually observing core lithology, provide basic information but suffer from strong subjectivity and limited precision.rock core drilling rig

  1. With technological development, various advanced analysis methods have emerged. X-ray diffraction (XRD) analysis can precisely determine mineral types and contents in cores, offering accurate mineral composition data for mineral exploration.
  2. Scanning electron microscopy (SEM) allows observation of core microstructures, which is effective for studying rock pore structures and particle contact relationships. This helps improve understanding of reservoir characteristics and enhance exploration accuracy.
  3. In an oil-gas field exploration project, combining multiple core analysis methods—first using XRD to determine mineral composition, then using SEM to observe micro-pore structures—comprehensively and accurately evaluated reservoir quality. This significantly improved exploration accuracy. Compared with single methods, it enables deeper and more accurate understanding of subsurface geology, providing more reliable basis for exploration decisions.rock core drilling rig
