摘      要：Tight oil in Yanchang formation, late Triassic, formed in fairly deep lake to deep lake sedimentary facies, is a kind of tight sandstone oil. With typical cases of that in Chang7 oil-bearing layer and Chang6 oil-bearing layer （in central part of the basin）, the tight oil is rich in resources.
