| Outline and Purpose of the Course | In this course, we will give lectures on i) in-situ rock stress and its measurement methods, ii) physical properties and mechanical properties of rocks under large depths determined by laboratory experiments, borehole logs and geophysical survey. We will introduce new research results related to the above items in geoengineering and geoscience research areas. | ||
| Course Goals | Understand the representative physical properties of rocks under high-temperature and high-pressure conditions, in-situ stress and its measurement methods and their applications in earth resource development field and in deep scientific drilling projects. | ||
| Schedule and Contents |
Guidance: 1 class by Weiren LIN Introduce the contents of the course. Rock stress and its measurements: 5 classes by Weiren LIN Measurement methods of in-situ stress such as borehole compressive and tensile failure analyses, hydraulic fracturing, core-based methods; introduction of the new research achievements. Physical properties and strength of rocks: 4 classes by Weiren LIN Physical properties (elastic wave velocity, resistivity, fluid flow and thermal properties) and mechanical properties (strength and deformation). Logs and physical property analyses using log data: 2 classes by Saneatsu Saito, Principles, operation procedures, data processing and interpretation of results in deep drilling wells. Crustal deformation and physical property, 2 classes by Kazuya Ishitsuka Estimation of geological and physical property distribution in wide areas by explorational and remote sensing data. Feedback: 1 class by the all. |
