Research on the Moveable Oil in Tight Oil Reservoir with NMR and Centrifugal Experiment

Abstract:

In order to quantitatively analyze the contents and distribution of the moveable oil in tight oil reservoir, this research has done experiment on 12 representative cores. The total moveable oil saturation is between 5.17% and 43.30%. And the big throat controls less contents of moveable oil than the small one, throat radius between 0.02μm~0.1μm plays the leading role, and nanometer throat controls most of the pore space of moveable oil. Comparing with permeability higher than 0.1mD, permeability between 0.03mD~0.1mD, permeability between 0.01mD~0.03mD, permeability lower than 0.01mD, the first one has the biggest content of the total moveable oil, and its moveable oil is mainly controlled by throat radius between 0.02μm~1.0μm, while the moveable oil of permeability between 0.01mD~0. 1mD reservoir is mainly controlled by throat radius less than 0.1μm, and the other reservoir is mainly controlled by throat radius between 0.02μm~0.05μm.
