摘要

In this paper, the oil injection experiment is used to mensurate the oil immission critical press on different confining pressure. On the base of the data, the relationship between the oil immission critical press and depth has been studied. Last the reservoir interpretation chart of low-permeability sandstone is established base on the relationship above. The oil injection experiment indicates the minimum injection porosity is 10.5%. The oil can not been injected into the sample when the property and permeability are lower than 10.5% no matter what press applied. The results are all accord with the test of Chang-8 reservior, and the interpretation chart of low-permeability sandstone make a good effect in lithological reservoir exploration practice of Chang- 8 Member, Zhenjing area.
