摘　　要：气井加砂压裂后 ,有效的返排压裂液并控制出砂 ,对下一步的测试和采气工作有重要影响。文章针对产能高且自排能力较高的地层 ,分析了诸多影响出砂因素后 ,提出了加砂压裂后排液及防砂措施。经现场应用 ,取得了较好的效果。Effective discharge fluids and sand control after sand fracturing have an important influence on the well test and gas production in the next stage. In the paper, in light of the strata with high deliverabilities and high self-discharge capacities, some measures of discharge fluids and sand control after sand fracturing are put forward through analyzing many factors of effecting sand production. A good result has been achieved by applying on the spot.
