Description:
The present work considers numerical models of large rock inclusions (stringers) are embedded in many salt bodies. The study has been made to investigate the influence of salt tectonic process, such as downbuilding, on the deformation and displacement of stringers. In this research, the focus has been on establishing numerical models of the deformation and displacement of stringer embedded in salt (at rest) after occurrences of salt tectonics. The problem of influence of eventual tectonic processes at larger stage is addressed on the development of stringers. The numerical model is based on finite element method in combination with adaptive remeshing. The results show that the stringers experience minor sinking and the differential stress in salt and the differential stress in the stringer decrease during the period after salt tectonics. The change of stress of reservoir will influence drilling process and oil or gas production.
