Abstract: Experimental on fluidity of low permeability reservoir for Xiao 22-14-20 reservoirs of liaohe huangshatuo area was carried. The results show that water sensitivity is medium but slightly,critical salinity is bellow 2 500 mg/L,configuration of relative permeability curve basically presented that oil phase descended quickly,water phase rised rapidly and span of oil-water phase is small,which is the characterizes of fractured oil reservoir relative permeability curve.In the course of water development,it is necessary to ensure sufficiently standard quality and avoid pollutting and building up pay zone.The plan of water flood recovery to keep energy have been performed,the rate of recovery have been improved comparing natural recovery.
