Abstract: The tight sand reservoir with high pressure and low permeability in Kuqa foreland basin is divided into three types in terms of lithology and physical property, and its well-logging responses and fracture distribution are reviewed. By in-depth analysis of such a reservoir, its standard chart for evaluation of the reservoir is established, providing a new thought and/or method for complex reservoirs by well-log evaluation.

Key words: high pressure and low permeability, fractured sand reservoir, foreland basin, well log evaluation
