A comprehensive review on the forming mechanisms of typical tight-sandstone hydrocarbon reservoirs was presented. 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 composite tight sandstone reservoir. Through theoretical calculation,tight-sandstone hydrocarbon resources in China were reappraised. The results reveal far more potential hydrocarbon resources than estimated before. The conventional hydrocarbon resources discovered so far account for less than 25% of the total basin hydrocarbon resources,while more than 75% of hydrocarbon 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 explorations and sustainable developments.
