S4潜山凝析气藏改建储气库可行性研究

S4储气库为SQ储气库群的一部分,定位为季节调峰及应急供气型储气库。建成后即可充分利用H油田良好的地质条件、地域优势和完善的地面已有设施等建库资源,满足京津冀晋地区快速增长和季节用气峰谷差的天然气市场要求,对于优化京津冀地区能源结构,推进区域低碳、清洁发展具有重大意义。针对目标区,从气藏地质特征和气藏工程两方面入手,对气藏圈闭、构造特征、盖层特征、储层物性、气体性质、储量规模、地层压力、动态储量、采出程度等方面进行了可行性分析。结果表明,区块的盖层密封性以及边界断层的侧向封堵作用比较良好,具备建库的基本地质条件;气藏储量较大,采出程度较高,为改建储气库提供有利条件。此外,规划设计了储气库的运行参数,为具体实施建库项目奠定了基础。

Feasibility to Build Underground Gas Storage in S4 Buried Hill Gas Condensate Reservoir

S4 gas storage is part of SQ gas storage group, positioning for the seasonal peaking and dealing with the sudden events. After completion it can take full advantage of favorable geological conditions, geographical advantage and other resources of H oilfield, meeting the requirements of the natural gas market at area of Beijing, Tianjin and Hebei. It could also optimize the energy structure of Beijing, Tianjin region and promote the development of regional low-carbon. Aiming at the position, the feasibility is analyzed on the trap, structural variation, coverage features, reservoir physical property, gas property, reserve scale, gas recovery ability and etc. The operation parameters are designed, which are the ground to perform the storage - building project.
