The main purpose of this study is to investigate and structureral analyzes of Sirri oil field by subsurface geophysical data. In order to Seismic interpretation from 3 seismic lines (LL3, LL4 and LL5) picked up by Iranian Offshore Oil Company and SIC-1 well Data was used. In addition to interpreting the geological horizons and understanding the stratigraphic-structural evolution of the region they have also been used. The study area is located in the south of Iran and in the Persian Gulf. In this study, the geological analysis of the area has been studied by two-dimensional seismic surveying method and petrophysical images (up to Darian Formation) and Petrel software. The results show that the rising of the salt dome related to the Hormuz series has affected the overlying Formations in these field, and has created a dome shaped state for most of the Formations. Rising of the salt and folding of the sediments eventually resulted in faulting of the sediments. During the study and measurement of the angle between the edges, it was found that 15.2% of the folds are open and 84.8% are of the soft folds.
