摘　　要：涩北一号气田经过多年的开发,获得了可观的天然气产量,增加了国内天然气供应,积累了丰富的开发经验,但也遇到了出砂、出水、储量动用差异大等问题。目前,涩北一号气田采出程度已经超过10%,达到了动态储量评价条件。采用物质平衡压降法计算动态储量,通过对影响气田气井动态储量的试井解释渗透率、出水、压力等因素进行综合分析,认为影响气井动态储量的主要因素是渗透率。该认识为提高涩北气田储量动用以及其他类似气田的开发提供了参考依据。After years of development,the Sebei 1 gas field has accumulated a wealth of experience,but also encountered problems such as sand,water,great changes in dynamic reserves,etc.To date recovery percent of this gas field is over 10%,reaching the lower limit for dynamic reserve evaluation.In this paper,material balance-pressure drop method was used to calculate the dynamic reserves,and influencing factors of dynamic reserves were analysed for this gas field.Based on a comprehensive analyses of permeability,water,pressure and other factors on the well test interpretation,it is pointed out that permeability is the dominated influencing factor,which provide a reference to the application of the Sebei gas field reserves and development of the gas field.
