摘　　要：涪陵页岩气田治理气井出砂方法大多着眼于压裂试气,缺少基于采气生产过程中出砂判断和治理方法。分析出砂井的生产数据,发现可以通过气井瞬时流量持续上升、瞬时流量异常波动来第一时间判断气井出砂,也可以通过设备异常来直观观察气井出砂情况。实践表明,在合理配产的基础上从地质与工程两个方面着手治理出砂井,可收到较好的治理效果。The treatment of sanding in the Fuling shale gas field were largely focused on fracturing gas testing,lacking identification of sanding and treatment amid gas production. It is found that the sanding of a gas well can be identified at the first time by the continuous rise or the abnormal fluctuation of instantaneous flow based on the analysis of production data of a sand producer.The results show that,on the basis of proper proration of production,the sand producer can be treated from both geological and engineering aspects.
