Microscopic Characteristics of Water Flooding and the Affecting Factors of Low-Permeability Sandstone Reservoir in Zhidan Area, Ordos Basin, China

This paper is to analyze the issues arose during water-flooding exploitation of the low-permeability sandstone reservoir in Ordos Basin, China, and to provide relevant theoretical supports. The method of sandstone micro-model for water flooding experiment was used here to simulate water flooding process, in order to analyze the characteristics of water flooding in low permeability sandstone reservoir from the microscopic view. In addition, the...
