摘　　要：在实际生产过程中,压降曲线在反映气井压力变化的同时,可以用来推测气藏是否封闭、是否有能量补充等,其重点是对压降曲线类型的判定和利用其进行气井控制储量的计算。统计涩北气田相关资料,得到各开发层组测压井单井压降曲线,对其进行分类,对井控储量进行计算。结果表明,利用压降指示曲线计算气井控制储量简单、可靠。In the actual production process,at the same time of the down pressure curves reflect the changes of pressure for gaswell,it can also be used to inferweatherthe gas reservoir is closed,and there is energy supplementation or not,whose importance is to determine the type of down pressure curves and use it to calculate well control reserves for gas well.By Statistic information of the Sebei gas field,single-well pressure drop curve of the measured pressure wells of each development group is received,and well-controlled reserves are calculated.The results showthat using down pressure index curves to calculate control reserves for gas well is simple and reliable.
