Abstract:A layered structural model for site selection of gas storage in aquifer was established. Based on the results regarding the underground gas storage(UGS) and the worldwide UGS databank,and a standard of index classification was put forward. The qualitative and quantitative methods with the extensible elements and extensible dependent function were used in the model. Finally,this method was applied to evaluate the suitability of building gas storage in aquifer in oilfield of Huabei. The results of evaluation showed that the sites Da 5 and Ge 2 were suitable to build gas storage in aquifer,and that the developed approach was reasonable.
