摘　　要：为实时掌握气井产能,准确评价气井在生产过程中产能的变化规律,制定不同时期的合理配产,基于气井初期产能测试数据得到的气井产能方程,利用Topaze气井生产动态分析软件开展单井生产动态历史拟合,得到气井地层压力的变化史,计算不同时期、不同地层压力下气井绝对无阻流量。在埃及K气田K-5井、K-6井、K-7井生产管理过程中,通过适时的气井优化配产,实现气田稳定生产,取得了较好的效果。该方法可有效减少气井产能测试及气井运营管理成本,进而指导气井配产,实现整个气藏的高效合理开发。To grasp the gas well productivity in real time,accurately evaluate the change law of well productivity during production,and define a rational production allocation in different periods,the gas well productivity equation was obtained from the initial productivity test data of gas well.The production performance history matching of single well was completed by using TOPAZE,a production performance analysis software,to determine the change history of formation pressure of gas well,and the absolute open flow of gas well in different stages and at different formation pressures was calculated.In the production management of Wells K-5,K-6 and K-7 in K gas field,Egypt,the stable production was realized through timely optimization of well production allocation.This method can effectively reduce the costs of gas well productivity test and gas well operation management,and guide the production allocation of gas wells,so as to realize the efficient and reasonable development of the whole gas reservoir.
