摘要：
With the characteristics such as low porosity, low permeability, strong heterogeneity, tight sandstone, and complexlogging response of tight sandstone reservoirs, the gas identification and evaluation are difficult with multiple solutions. The peak energy and a weighted cumulative quantitative are applied in the paper to analyze features of multi-scale wavelet and wavelet packet analysis based on three-water model, cores, geological and gas test data in tight sandstone gas reservoirs. Then the appropriate method of multi-scale wavelet energy spectrum of tight sandstone gas reservoirsis selected to identify tight sandstone gas in Sulige region, which achieved good effect. © 2016, Editorial Department of Earth Science.
