The recovery scheme for most China's low permeability reservoirs is water flooding,however,it's difficult to get the key data of relative permeability in water flooding by conventional experiment.The steady state experiment and non-steady state experiment of getting relative permeability curves with low permeability cores is raised based on scanning.In steady state methods,in view of the fact that it's difficult to get steady state,steady judgement bases are given based on CT scanning data.The adoption of 1...
