气顶油藏改建地下储气库的可行性

Feasible Analysis to Build Underground Gas Storage in Es1 Gas Cap Reservoir of Shengtuo 1st District of Shengli Oilfield

从解决山东天然气市场突发事件应急和季节用气调峰而建设小型地下储气库的需求出发,确定了胜利油气区地下储气库库址的优选标准,优选出气库目标区—胜利油区胜坨一区Es1气顶油藏。针对目标区,从气藏圈闭、构造变化、盖层特征、储层物性、气体性质、储量规模、采气能力、采出程度和地面流程等方面进行了可行性分析,规划设计了储气库的运行参数,部署了气库井位,为现场实施奠定了研究基础。

For the sake of establishing miniature underground natural gas storage to meet the demand of urgent needs and gas season peak shaving of Shandong natural gas marketplace,optimized criteria of choosing underground natural gas storage site are defined,and underground natural gas storage target,Es1 gas cap reservoir of Shengtuo 1st district in Shengli Oilfield,is picked out.Aimed at underground natural gas storage target,the systemic feasibility analysis,such as gas entrapment,geological structure,capping formation,reservoir characteristic,natural gas property,original gas reserves,gas productivity,gas recovery efficiency and gas pipeline construction,are carried out.After that,operating parameters of underground natural gas storage are planned out,and well sites of gas storage are designed.Analysis and design provide a research base for the performing production of miniature underground natural gas storage.
