Abstract: In order to clarify the genesis and favorable exploration area of“below the source rock”tight oil of the 4th member of Cretaceous Quantou Formation in Putaohua Oilfield of northern Songliao Basin，tight oil types and distribution characteristics of different structural units were identified through fine characterization for source rock characteristics，migration channels，hydrocarbon-generating pressurization，high-quality reservoir characteristics. Hydrocarbon accumulation models were established for each structural unit. The results show that： （1）High-mature source rock in the 1st member of Qingshankou Formation of Gulong Sag is the material basis for the tight oil reservoir accumulation of the 4th member of Cretaceous Quantou Formation in Putaohua Oilfield. High-quality reservoirs with porosity greater than 10% are good for the enrichment of tight oil. The “L-type” migration channels composed of faults and river sandbodies are the necessary guarantees for tight oil lateral migration. （2）The 4th member of Cretaceous Quantou Formation underwent 2 main accumulation period. The overpressure of 19.6-23.5 MPa formed by hydrocarbon-generating pressurization in late Mingshui Formation，is the main power for oil and gas to flow backward and form “below the source rock” tight oil （. 3）Four kinds of tight oil reservoirs，such as fault-lithologic oil reservoirs，fault reservoirs，sandstone lens oil reservoirs，updip pinch-out lithologic oil reservoirs，are developed in the 4th member of Quantou Formation. Maoxing syncline mainly develops small-scale sandstone lens and fault reservoirs，with scattered oil bearing areas. While Toutao nose-bulge develops updip pinchout lithologic oil and fault reservoirs，with good oil bearing. And Punan nose-bulge mainly develops fault and fault-lithologic oil reservoirs，with oil and gas continuously distributed in large expanse.（4）The accumulation of tight oil reservoir is controlled by hydrocarbon generation centers，“L-type” migration channels，overpressure and reservoir quality. The accumulation models of Maoxing syncline，Punan nose-bulge and Toutai nose-bulge are “upper-generation and lower-storage, overpressure drive within source rock，oil and gas backflow，and part ‘sweet spot’enrichment”， “source-reservoir adjoining，fault-sandstone relay L-type migration，upper aggregation”，and “source-reservoir separation，fault-river lateral migration and accumulation，and high-quality reservoir enrichment”，respectively. Punan nose-bulge is the favorable exploration area for tight oil.

Key words: tight oil, below the source rock, "L-type" migration channels, overpressure, updip pinch-out lithologic reservoir, the 4th member of Quantou Formation, Cretaceous, Putaohua Oilfield, Songliao Basin
