摘　　要：随着天然气工业的快速发展,天然气储气能力建设进入黄金发展期,但国内优质建库资源越来越少,亟需探索天然气储气能力建设新模式。利用在产天然气藏或新开发天然气藏实现气藏开发协同季节调峰,具有见效快、规模大、投资少的优势,是目前快速提升天然气储气能力的一个重要方向。但季节调峰的非均衡生产必然影响在产气藏的稳定性。为此,通过建立季节调峰对气藏开发影响最小的选区目标函数,利用统计分析、数值模拟等方法,从地质、开发、地面、市场特征等方面系统分析了不同参数对在产天然气藏季节调峰选区评价的影响,明确了主控因素,制订了气藏调峰分级指标评价标准,并研发了在产气藏选区评价子系统。研究结果表明:①提高在生产气藏合理配产,可快速形成调峰能力,对天然气调峰保供具有重要作用;②建立的在产气藏季节调峰选区评价体系,可有效降低季节调峰破坏气田开发效果情况发生的风险;③建立的在产气藏选址评价指标体系、标准及方法可有效支撑目标区的筛选评价,研发的在产气藏选区评价子系统提高了筛选评价效率和精度;④将在产气藏筛选评价子系统集成到储气库综合管理平台可实现油藏型、含水层型、盐穴型、在产气藏季节调峰型4类储气库的筛选评价。结论认为,将研发的在产气藏季节调峰选区评价子系统集成到中国石化储气库综合管理平台—选址优化模块,实现了中国石化储气库综合管理平台的迭代升级,有效指导了在产天然气藏季节调峰选区评价,对快速提升储气能力和国内其他储气库建设有指导意义。With the rapid development of natural gas industry,the construction of gas storage capacity enters a golden period.In China,however,high-quality resources for building underground gas storage(UGS)are becoming increasingly scarce,so it is urgent to actively explore a new mode of gas storage capacity construction.Use of producing or newly developed gas reservoirs to achieve reservoir development coordinated with seasonal peak-shaving has the advantages of fast effectiveness,large scale,and low investment,and it is an important direction for rapidly improving gas storage capacity.Nonetheless,the unbalanced production of seasonal peak-shaving has an inevitable impact on the stability of producing gas reservoirs.To this end,this paper establishes an objective function that minimizes the impact of seasonal peak-shaving on gas reservoir development,and systematically analyzes the impact of different parameters on the evaluation of producing gas reservoir for seasonal peak-shaving from the aspects of geological,development,ground and market characteristics,by means of statistical analysis and numerical simulation.The main control factors are determined,and a four-level index evaluation standard is formulated.Moreover,a producing gas reservoir evaluation subsystem is developed.The following results are obtained.First,improving the reasonable proration of producing gas reservoir can achieve peak-shaving capacity rapidly,and plays an important role in peak-shaving and supply guarantee of natural gas.Second,the established evaluation system of producing gas reservoir for seasonal peak-shaving can effectively reduce the risks that seasonal peak-shaving damages gas field development effect.Third,the established evaluation index system,standard and method of producing gas reservoir provide an effective support for the evaluation of target zones,and the developed evaluation subsystem of producing gas reservoir improves the evaluation efficiency and accuracy.Fourth,integration of the evaluation subsystem of producing gas reservoi
