| Abstract: | Analysis of the tectonic stress field plays an important role in petroleum accumulation dynamics simulation.The current study on stress field is mainly focused on two-dimensional analysis of plane.With development of the three-dimensional simulation of petroleum forming process,three-dimensional numerical simulation of stress field becomes increasingly important.In this paper,the finite element simulation of stress field and solution of the whole process,based on three-dimensional space,are discussed.After ... |
