摘　　要：国内多数气井渗透率低,需要压裂改造才能获得工业产能,压裂后气井的产能影响因素复杂,不仅与地质因素有关,还受施工效果的影响。文章主要从地质条件、储层物性参数、压裂裂缝参数、流体流动特征4个方面出发,对长庆榆林气田影响压裂气井产能的诸多因素进行了深入细致的剖析,在此基础上形成了一些针对性的压裂气井开发建议,对促进低渗透气藏的经济高效开发具有一定的指导意义。Most gas wells show low permeability in China,and need to be stimulated by fracturing to acquire industrial deliverabili-ty. After fracturing,the influential factors of gas wells'deliverability are very complicated. Based on the geological conditions,reservoir physical properties,artificial fracture parameters and fluid flow char-acteristic of Changqing Yulin gas field,the factors of influencing fractured gas wells deliverability were analyzed detailedly,some aimed suggestion on fractured gas wells production was put forward,which may make certain guiding sense to improve low permeability reservoirs'development level.
