摘　　要：冷采被用作一种新的采油工艺可以成功地用于未胶结砂岩中的稠油。采用大孔径、深穿透、高密度射孔技术对稠油出砂冷采是必须的 ;采用适应高含砂量和高原油粘度的高转速螺杆泵 ,且螺杆泵下入油层底部等引流技术措施对出砂冷采是十分有利的。New technology-cold recovery can be successfully used in unconsolidated sandstone reservoir.The result indicates that a cold recovery well must be perforated with close holes of large diameter and deep penetration, with speed rotation screw pump suitable for high sand cut and high viscosity placed at bottom of oil layer,which is favorable to cold recovery.
