盐岩储气库适用性评价标准的研究

目前国内还没有对盐岩储气库的适用性提出全面的评价标准。在研究地下储气库失事案例之后，提出了储气库适用性评价标准（ESAGSRS）。该标准分为稳定性和密闭性两方面。稳定性从储气库顶和底板的性质、盐岩层及夹层的性质、夹层与盐岩层交界面的性质、溶腔最大与最小运行压力及注采速率、溶腔形状及矿柱距离5方面进行评分；密闭性则从储气库的固井技术、套管的性能、套管阀门的性能、溶腔压力、顶板性质、夹层性质、盐岩的渗透条件、夹层与盐岩层交界面的刚度比，地质构造条件等方面进行评分。将稳定性与密闭性的得分按比例相加，用所得总分来评价储气库的适用性。该标准较为全面地考虑了各种因素，可为工程实践提供一定的参考价值和理论支持。

Study of evaluation standard of applicabilities for gas storage in salt rock

At the present,nobody proposes a comprehensive evaluation standard of applicabilities for gas storage in rock salt(ESAGSRS).ESAGSRS is came up based on studying a large number of underground gas storage accident cases.The standard is divided into two aspects,stability and sealability.Factors affecting the stability are natures of top and bottom,natures of salt beds and interlayers,natures of interface between salt beds and interlayers,the maximum and minimum pressures and gas recovery velocities,cavity shape and safe pillar width five aspects.Factors affecting the sealability including airtight cementing technology,natures of casing,natures of valve for casing,cavern pressure,natures of roof,natures of interlayer,penetration of rock salt conditions,stiffness ratio of salt rock and interlayer,geological conditions.Based on ESAGSRS,the total score of the applicability of gas storage can be gotten,and it can appraise the applicability of salt rock.The standard(ESAGSRS) considers miscellaneous factors,and it has a valuable reference and academic supports to practical projects.
