摘　　要：随着大庆油田原油、伴生气产量逐年递减,冬夏季供气不平衡的矛盾日益突出,在无法满足季节调峰需求时,需压减工业用气。因此,从满足冬季下游用户的用气需求、合理利用有限的油气资源和保护环境等角度出发,建设储气库势在必行。根据大庆油田库址筛选标准,优选出A区块进行库址规划,与大庆油田已建储气库相配合,联合保障大庆及周边地区用气季节调峰。A区块属于砂泥岩薄互层气藏,从地质特征、气藏开采特征等方面分析改建储气库的可行性,详细评价建库的地质条件和气藏条件,并设计库容参数和两套井位部署方案,建立数值模型进行优选对比。结果表明,A区块砂泥岩薄互层气藏具备建库的可行性。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 rational 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 selected 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.
