| Research Abstract |
A technology that can evaluate seal ability of a structure type oil trap is a very important problem in searching and developing oil fields. However, for such a basic problem, the theoretical development which could sponsor a clear answer was difficult until now. To solve these problems, development of a simulator forbedrock faulting which intended for the oil reservoir was investigated using a DEM (Distinct Element Method) in this research project. The Distinct Element Method adopted in this research and its advanced techniques have been used as useful simulation methods in the field of engineering works. These are known as very strong tools in an application to a destruction phenomenon. However, it is a unique point and a characteristic of this research that applied DEM to geological problems.
At first stage of the project, the simulator which could reproduce a destruction phenomenon was developed. However, because algorithm development was difficult to the handling of the formation of fault gauzy planned at first, we were incomplete to develop this functions. The simulator developed here, can apply to the oil reservoir analysis which can investigate a history of formation of thrust fault series and this approach created a new research field. Connection with structural geology was necessary in order to consider these simulation results. So connection with the sandbox experiment that could reproduce history of structure development was pushed forward.
