摘　　要：针对苏里格气田影响气井产能的因素,研究了地层系数、储层非均质性、非达西流系数以及储层含水对气井产能的影响。结果表明气井产能与地层系数线性相关;储层非均质对气井产能影响较大,产能、压力测试时间应更长一些,使气井流动达到拟稳态,以真实反映气井产能的大小;非达西流系数越大,产能系数越大,气井产能越低;含水层所处的部位不同对气井产能的影响程度也不同。In consideration of the productivity influential factors of gas wells in Sugeli Gas Field,the influence of formation coefficient,reservoir heterogeneity,non-Darcy flow coefficient and water content on the productivity of gas wells was studied.The result shows that the productivity is related with the linear of formation coefficient,the reservoir heterogeneity has higher influence on the productivity,the times of productivity and pressure testing should be longer,so that flowing in gas wells is pseudostable to reflect the size of productivity ingas wsells;the higher the non-Darcy flow is,the bigger the productivity coefficient is,the low the production rate of gas wells would be.The level of influence from different water-cut locations has different effects on productivity of gas wells.
