摘　　要：由于北京市冬夏季用气量差在 7倍左右 ,而仅仅依靠输气管线自身调节能力 ,远远不能满足相差如此悬殊的供气与用气矛盾 ,因此急需建立地下储气库解决供需不平衡问题。大张坨地下储气库的建设即是在此背景下提出的我国第一座大型地下储气库建设项目。文章通过国内外有关资料的调研分析 ,总结出地下储气库建库地质筛选原则 ;并以大张坨地下储气库地质设计方案研究为例 ,在对该气藏的构造、圈闭、断层、储层、盖层等进行深入的建库地质分析及评价基础上 ,综合利用多种方法落实了气库库容量 ,并结合北京市用气规律动用物质平衡原理和数值模拟技术设计了气库运行基本指标 ,同时利用试井资料及气井节点法计算软件确定了气井合理产能。在此基础上设计并优选了设计指标 :工作气量为 6 .0× 10 8m3 ,日调峰为 5 0 0× 10 4 m3Because the difference of gas consumption between in winter and in summer is about seven times,only depending on the adjustment ability of the gas transmission pipeline itself is far to solve so great contradiction between the gas supply and the gas consumption.For this reason,it is urgently necessary to build an underground gas storage to solve the unbalance between the supply and the demand.Against this background,the building of Dazhangtuo underground gas storage—a project of the first large scale underground gas storage in China is proposed.In this paper,through investigating and analyzing the foreign and domestic relevant data,the principle of selecting geological structure for building the underground gas storage is summarized;taking the research of the geological design plan for Dazhangtuo underground gas storage for example, the storage volume is ascertained by using multiple methods on the basis of the thorough geological analysis and evaluation of the structure,trap,fault,reservoir and cap rock,etc.of this gas reservoir;the basical running targets of the gas storage are designed by combining with the gas consumption law in Beijing city and applying the material balance principle and numerical simulation technique;the rational gas well's productivity is determined by utilizing well testing data and the nodal method calculation software and based on this,the running program of the gas storage is designed and optimized.The designed targets are as follows:The working gas volume is 6.0× 10 8m 3 and the daily peak shaving volume is 500×10 4m 3.
