摘　　要：以辽河油田黄沙坨地区小22-14-20油藏为研究对象,进行了低渗油藏储层流动性室内实验研究。结果表明,该油藏水敏性为弱水敏至中等水敏,临界矿化度在2 500 mg/L以下,相对渗透率曲线的形态基本上呈油相相对渗透率下降迅速,水相相对渗透率上升急剧陡峭,油水两相相对渗透率跨度小的裂缝性油藏的相渗曲线特征。在注水开发过程中,充分保证水的标准质量,防止油层的污染堵塞。现场实施结果表明,实施注水采油保持能量是可行的,采出率由10.8%提高到11.96%。Experimental on fluidity of low permeability reservoir for Xiao 22-- 14--20 reservoirs of liaohe huangshatuo area was earried. The results show that water sensitivity is medium but slightly,eritieal salinity is bellow 2 500 mg/L,configuration of relative permeability eurve basieally presented that oil phase deseended quiekly, water phase rised rapidly and span of oil-- water phase is small, whieh is the eharaeterizes of fraetured oil reservoir relative permeability eurve. In the eourse of water development,it is neeessary to ensure suffieiently standard quality and avoid pollutting and building up pay zone. The plan of water flood reeovery to keep energy have been performed, the rate of reeovery have been improved eomparing natural reeovery.
