Feasibility Study on Converting a Sand-mudstone Thin Interbedded Gas Reservoir into a Gas Storage in Block A
With the decline of crude oil and associated gas production in Daqing Oilfield year by year,the contradiction of unbalanced gas supply in winter and summer is becoming more and more prominent.When the seasonal peak shaving demand cannot be met,industrial users will be reduced for gas.Therefore,in order to meet the increasing gas demand of downstream users in winter,make ratio-nal use of limited oil and gas resources,and protect the environment,the construction of gas storage is imperative.According to the selection criteria of the reservoir site in Daqing Oilfield,block A is select-ed for planning reservoir site,which cooperates with the built gas storage in Daqing Oilfield to jointly ensure seasonal peak shaving in Daqing and surrounding areas.Block A is a thin interbedded gas reservoir of sand-mudstone.The feasibility of rebuilding the gas storage is analyzed from the aspects of geological characteristics and gas reservoir production characteristics.The geological conditions and gas reservoir conditions for the construction of the reservoir are evaluated in detail,the reservoir capacity parameters and two sets of well location deployment schemes are designed,and a numerical model is established for optimization and comparison.The results show that the sand-mudstone thin interbedded gas reservoir in block A has the feasibility of building a reservoir.
