摘　　要：低渗气田气井产量波动较大,在Arps产量递减分析中较难确定递减类型。尝试采用奇异点剔除、开井时率校正等气井生产数据前处理方法,以减小气井产量波动对递减规律分析结果的影响;同时,利用气井动储量作为递减类型判识依据,提高递减类型判识的可靠性。Due to fluctuation of production rate in low permeability gas reservoir,it is difficult to determine the type of decline curve with ARPS method. By means of deleting of singular point and correction of well-opening time,the effect of fluctuation of production rate on decline law is reduced; meanwhile,dynamic reserves is used as the standard to enhance the reliability in discrimination of decline type.
