Abstract

This study focuses on a rock salt exploration project and investigates the geophysical well logging data from six boreholes (DZK1–DZK6). First, the well logging operations are systematically reviewed, including survey objectives, instrumentation, technical parameters, quality control measures, and interpretation results, confirming that the acquired data are complete, accurate, and reliable. Subsequently, in accordance with standards such as the Technical Specifications for Three-Dimensional Geological Modeling, the applicability of using the logging dataset to construct a high-precision three-dimensional geological model of the rock salt deposit is comprehensively evaluated from multiple perspectives, including data foundation, technical feasibility, potential risk factors, and expected modeling accuracy. The results indicate that the logging data of the rock salt deposit are of high quality and fully meet the data input requirements for three-dimensional geological modeling. By adopting a scientifically sound technical workflow and appropriate risk mitigation strategies, a three-dimensional geological model with controllable errors and clear geological significance can be successfully established. The model can provide robust technical support for resource evaluation, optimization of mining schemes, and comprehensive utilization of geothermal energy in the mining area.
