Numerical modeling of folding Lali oil field Using Finite Element Method

This paper, a two-dimensional model of Lali oil field and faults of the northern and southern edges of the relations with ABAQUS software based on finite element methods. The model results from Geodynamic Geodesy area networks and the tectonic stress as a constraint problem has been logged and various field formations on the elastic properties is considered. Fault surface is covered with contact elements that have authority to slip influence and change their shape and according to this properties in surface properties can well indicate the fault. Modeling results and geological criteria (Geodesy results) were compared and good coordination is observed between the results of the validation criteria. Results with a different coefficient of friction compared to the rate of displacement of GPS stations that coordination is more pronounced in the coefficient of friction 0.02. Displacement of southern edge of the fault in both friction 0.02 and 0.1 are obtained, respectively, 6.3 and 11 mm/year. The modeling results also showed that fault at different depths has different displacements and at depths less, move more expressive. Faults north and south edges of the integration Lali anticline that the most stress have focused on their, is Stress concentration and critical fault location of the fault.
