摘　　要：储气库是下游用户用气调峰、国家能源安全的重要保障，在天然气的开发和利用过程中有着举足轻重的作用。地下储气库单井注采能力是储气库建设中的重要参数，是气库正常运行的重要保证。长庆靖边气田陕45井区目前仅对6口I类生产井进行了系统试井，且气藏储层非均质性较强，如何得到准确代表该区平均注采能力的二项式产能方程尤为重要。充分利用系统试井、单点法试并、压恢试并资料成果，应用稳定点产能二项式法．得到该区平均二项式产能方程，并结合Cullender-Smith井筒管流计算方法，通过节点分析，获得了该储气库建设区单井注采能力曲线，对工作气量、井数等储气库方案指标的确定具有重要的指导意义。The gas storage is the important s＇afeguard for the peak shaving of gas utilization of downstream users and the security of national energy source, and plays a critical role in the processes of the development and utilization of natural gas. The single-well injection and production capacity of the underground gas storage is the important parameter during the construction of gas storage, and the important guarantee for the nonual running of gas storage. Currently, the Shah No.45 well area in Jingbian gas field of Changqing only carries out the systematic well testing to 6 class-I production wells, and the anisotropy of the reservoir （s） of the gas reservoir （s） is strong. How to get the binomial capacity function representing the average injection and production capacity of the area accurately is very important. This article sufficiently utilizes the achievements of the data of systematic well testing, single-poinl well testing and build-up pressure well testing and applies lhe binomial method of stable-point capacity to get the average binomial capacity function, and combines with the Cullender- Smith wellhole pipe flow calculating method to get the curve of single-well injection and production capacity of the constnlction area of the gas storage, which is significant for determining the indexes of the gas storage schemes such as work gas amount, well number, etc.
