摘　　要：采用疏松砂岩油藏Z43断块岩心,通过室内出砂模拟实验,分析了流体流速、含水率、累积驱替液量和矿化度对岩心渗透率和出砂状况的影响。结果表明,在无水采油期,骨架砂未遭破坏,出砂轻微,可以携砂生产;在含水采油期,含水率对油藏出砂影响较大,应及时采取防砂措施。此外,注入水矿化度也会影响地层出砂量。Through the laboratory simulation test by using the core from unconsolidated formation in Z43 block, this paper analyzed the impacts of fluid flow rate, water content, cumulative displacement fluid and salinity of injected water on the core permeability and sand production performance. Study indicated that the skeleton sand was not destroyed and sand-earning production was available during water-free oil production. In the water-cut oil production period, the sand production was influenced by water cut greatly and sand control measures should be taken in time. Furthermore, the salinity of injected water could affect the sand production.
