摘　　要：深水储层胶结疏松,地层欠压实,开采过程极易出砂,需采取防砂完井措施。防砂方案优化需根据储层地质特征优选防砂筛管和优化挡砂精度。利用径向流挡砂驱替实验装置,模拟目标井生产制度对整体焊接精密筛管、双层预充填筛管、过滤型冲缝筛管以及防砂烧结筛管进行综合性能评价实验。实验结果推荐整体焊接精密筛管、过滤型冲缝筛管依次为目标井优选筛管类型,推荐40μm筛管标称精度为该井最优挡砂精度。Deep water reservoir features cementation, less formation compaction, and is easy to cause sand production problems. It needs to take sand control measures. The optimization of sand control design should base on the geologic characteristics of reservoirs and optimization of sand control precision. By using radial flow sand control displacement test device to simulate target well production system, an evaluation on the integrated welding precision screen, double prefilled screen, filtered type flushing screen and sand control sintered sieve was carried out. The results show that the precision of 40 μm sieve is the optimum precision value.
