Oil Charging Power Simulation and Tight Oil Formation of Fuyu Oil Layer in Sanzhao Area, Songliao Basin

A thermodynamic and hydrocarbon composition model based on VTFlinc software was conducted the homogenization temperature of fluid inclusions gas-to-liquid ratio, inclusions’ trapped pressure calculated. This does not require determination individual inclusions, simulation procedure is simple, result has certain reliability. The used to calculate oil in Fuyu tight reservoir Sanzhao area Songliao Basin. results show existence two phases charge. first phase occurred at end Nenjiang Formation 79–74 Ma with an entrapped 16.922–19.068 MPa, coefficient 1.18–1.26. During second period Sifangtai Mingshui group 69–64 Ma, 20.216–28.830 1.21–1.33. periods, abnormal, above 1.2. Abnormal high main driving force source rock Formation, as well important for lateral migration reservoir. formation a direct high-pressure charging multi-channel accumulation model.
