This invention relates to a method for identifying tight sandstone gas reservoirs, belonging to the field of oil and gas reservoir exploration and development technology. The method, based on original drilling data (field logging data and gas testing data), calculates the tight gas content index through parameter reconstruction. This index, geologically significant as a characterizing index of reservoir gas content, then establishes a correspondence between fluid properties in the study area and the tight gas content index and average sonic transit time. Finally, the fluid properties of the target layer are determined based on the tight gas content index and average sonic transit time. This method provides effective guidance for oil and gas exploration, evaluation, and development, improving the efficiency of drilling oil, gas, and water layer identification, reducing identification difficulty, and offering advantages such as simple operation, straightforward calculation, no need for highly skilled field personnel, high interpretation accuracy, and low processing time.
