Abstract :

In order to balance between gas produce and gas consumption in cold seasons which accounts as peak time, Gasstorage is as fundamental approaches which guarantee gas of country. In this regard, salt structure of Nasr Abadin Kashan has suitable potential and can be used as the largest site of natural gas storage in central Iran scope.Feasibility study with purpose of determining fault mechanism around the salt structure is an essential thing. Inorder to eliminate ambiguities, field operation is with analysis of the structure and kinetic geometry of faults ,right on the diversion channel , analysis of stereo graphic images, gravity interpretations such as documents ofstrike- slip activity with reverse component of Abshirin fault. Abshirin fault with a length of about 10 km, withapproximate distance of 2-3 km in salt structure is depreciated, which stands in a separation about 3.5 km towardDeh-nar fault as right stepping pattern arrangement . According to the obtained results, finally we concluded thatAbshirin faults and Deh-nar faults are not so significant impact on gas storage site.
