Abstract: The tight oil of Fuyu reservoir in northern Songliao Basin is a typical under-source tight reservoir,which has favorable geological conditions for forming large-scale and continuous tight reservoirs.Based on the analysis and statistics of a large number of experimental data and drilling data,the reservoir forming conditions of tight oil source rocks,sedimentary environment and reservoir characteristics of Fuyu reservoir in northern Songliao Basin are comprehensively analyzed.The study shows that the formation of tight oil in Fuyu reservoir is controlled by mature source rocks and delta front facies belt.The meandering river point bar sand body and distributary channel sand body have thin single layer thickness,fast lateral variation and vertical staggered links.Reservoirs are mainly micron-nano pore.The boundary between conventional reservoir and compact reservoir is 12% porosity,1×10-3μm2 permeability and 350nm pore throat radius.The internal boundaries of compact reservoir are 8% porosity,0.1×10-3μm2 permeability and 75nm pore throat radius.The main driving force of tight oil reservoir formation is hydrocarbon generation and pressurization of effective source rocks in the first member of Qinghai Formation,which belongs to the mechanism of inverted reservoir formation.Faults are the main migration pathway,and high-quality dessert areas are mainly distributed in the central part of Daqing Placanticline,Sanzhao Depression and west side of Qijia Gulong Depression.

Key words: Northern Songliao Basin, Fuyu reservoir, Micron-nanopore, Overpressure, Tight oil sweet area
