地下储气库是城市燃气季节性调峰和保证事故情况下安全用气的主要手段。由于天 然气需求受季节因素影响明显，冬季高峰时天然气消费量远大于夏季低谷时消费量，因 此需要储气库来进行调峰。随着天然气管线的快速建设和天然气需求的快速增长，目前 已有的地下储气库已远不能满足我国天然气管网和天然气市场的快速发展，有必要进行 新库的选址和建设。 本文以辽河油田双 6 区块砂岩枯竭型气藏作为研究对象，对砂岩枯竭型气藏的地质 条件从地层、构造、沉积、储层、隔夹层、盖层封盖性、圈闭有效性、油水分布、油藏 类型、流体及温压、储量开展了详细评价，对油气藏开发特征特别是水体对油气开发效 果的影响进行了研究，由此开展了油气藏数值模拟研究，通过开采动态历史拟合，对水 体侵入状况、剩余油分布及动用状况进行了研究，在此基础上，对改建地下储气库的单 井注采气能力、运行压力、运行方式和运行周期、4 类库容参数进行了详细研究。 通过上述详细的研究工作，得出了以下：双 6 区块砂岩枯竭型气藏具备改建地下储 气库的地质条件；因水体能量弱，并采用天然气顶驱开采方式，没有注水，水体侵入油 藏内部范围有限，边底水、原油对气顶影响小，具备改建地下储气库的地质条件的容积、 流体、温压、产能条件；初步确定了储气库技术指标和初步设计方案。 关键词：砂岩枯竭型气藏，地下储气库，双 6 区块，研究模式东北石油大学工程硕士专业学位报告 III Feasibility study of underground gas storage reconstruction of depleted sandstone gas reservoir ABSTRACT Underground gas storage is a city gas seasonal peak shaving and ensure the main means of gas accident safety. Due to the demand for natural gas was obviously affected by seasonal factors, the winter peak gas consumption is far greater than the summer doldrums when consumption, hence the need for gas storage peaking. With the rapid growth of demand for the rapid construction of natural gas pipeline and natural gas, the existing underground gas storage has been far from being able to meet the rapid development of China's natural gas pipe network and natural gas market, it is necessary for the new library location and construction. In this paper, Shuang 6 block in Liaohe Oilfield sandstone exhausted gas reservoir as the research object, the geological conditions of the sandstone gas reservoir exhausted from the stratum, structure, sedimentary, reservoir, interlayer, caprock sealing, trap efficiency, oil-water distribution, reservoir type, fluid temperature and pressure, carried out a detailed evaluation of the reserves. The characteristics of oil and gas reservoir development, especially the effect of water on oil and gas development effect is studied, which carried out the reservoir numerical simulation of oil and gas, by exploiting the dynamic history match of water invasion, remaining oil distribution and use status of the research status, and on this basis, the single well as underground gas storage the gas production capacity, operation pressure, operation mode and operation cycle, 4 types of reservoir parameters were studied in detail. The detailed research work, and obtained the following: shuang 6 block sandstone exhausted gas reservoir with reconstruction of the geological conditions of the underground gas storage; due to weak water energy, and the use of natural gas in the top of the flooding, there is no water, water invasion reservoir within a limited range, small influence of gas cap edge and bottom water, crude oil, with the reconstruction of the geological conditions of the underground gas storage volume, fluid, temperature and pressure, capacity conditions initially confirmed that the technology index of gas storage and preliminary design.
