     A comprehensive review on the forming mechanisms of typical tight-sandstone hydrocarbon reservoirs was presen- ted. Based on pattern matching between oil migration period and tight reservoir evolution, typical tight sandstone reservoirs were summarized into three catgories： conventional tight sandstone reservoir, deep basin tight sandstone reservoir and com- posite tight sandstone reservoir. Through theoretical calculation, tight-sandstone hydrocarbon resources in China were reap- praised. The results reveal far more potential hydrocarbon resources than estimated before. The conventional hydrocarbon re- sources discovered so far account for less than 25% of the total basin hydrocarbon resources, while more than 75% of hydro- carbon resources concentrate in tight sandstone reservoirs with low porosity （〈12%） and low permeability （〈10^-3μm2）. In the latter, over 25% of hydrocarbon concentrates in the tight conventional reservoirs, and over 50% in the tight deep-basin reservoirs. It is therefore suggested that tight hydrocarbon reservoirs remain the main focus in the future hydrocarbon explora- tions and sustainable developments.
