水攻法における水の注入に関する実験(コアによる測定)

抄録

For the purpose of improving the water injectivity for waterflooding, experiments on the injection of water using both oil field brine and artificial brine were carried out. Results obtained are shown on figures in this paper. These figures show that oil sand which contains clay is very sensitive to salinity of water and, therefore, permeability of the oil sand is extremely reduced by low salinity water.
