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.

结构式捕油圈密封能力评价技术是油田勘探开发中的一个非常重要的问题。然而，对于这样一个基本问题，迄今为止，很难提出能够给出明确答案的理论发展。为了解决这些问题，本研究项目利用DEM（离散元法）开发了适用于油藏的基岩断层模拟器。本研究采用的离散元法及其先进技术已成为工程领域中有用的模拟方法。这些被认为是应用于破坏现象的非常强大的工具。然而，将DEM应用于地质问题是本研究的独特之处和特点。在项目的第一阶段，开发了能够再现破坏现象的模拟器。但由于算法开发很难处理最初计划的断层纱的形成，因此我们对该功能的开发并不完善。这里开发的模拟器可以应用于油藏分析，可以研究逆冲断层系列的形成历史，这种方法开创了一个新的研究领域。为了考虑这些模拟结果，需要与构造地质学联系起来。因此，与可以重现结构发展历史的沙箱实验的联系被推进。
