Abstract：The shale oil resources are abundant in the first member of Qingshankou Formation, Upper Cretaceous, in northern Songliao Basin. The previous exploration was targeted at shale fractures and interbedded thin sands and ostracod layers. Due to the limitation of distribution range of target layers, the shale oil exploration results have not been satisfactory. Focusing on the widely-developed shale reservoirs in the basin, the survey refreshes the geological understanding of shale oil in the shale reservoirs of continental basin, and forms the exploration technology system. The industrial oil flows of SYY1, SYY2 and SYY3 wells pumped after fracturing yield 3.22, 4.93 and 3.46 m3/d respectively, the flowing high-yield industrial oil run of 14.37 m3/d from SYY-1HF well and pumping oil run of 10.06 m3/d from SYY-2HF well after fracturing, achieving a major breakthrough in the strategic survey of shale oil in northern Songliao Basin.
