Experimental Methods for the Quantitative Assessment of the Volume Fraction of Movable Shale Oil: A Case Study in the Jimsar Sag, Junggar Basin, China

Deep insights into the movability of retained shale oil are great significance to oil. Rock and crude samples were collected from well J174 in Jimsar Sag, Junggar Basin. subjected different extraction followed by analysis component extracts, measurement porosity conjunction with nuclear magnetic resonance high-pressure mercury injection analysis. The results these analyses used establish an experimental method for quantitative assessment movable extract content varied among between mud non-mud samples. saturated hydrocarbon extracts was similar those after CHCl 3 alone or sequential nC 6 + . aromatic significantly lower than , but opposite observed contents non-hydrocarbon asphaltene not higher viscosity negatively correlated hydrocarbon, positively non-hydrocarbon, asphaltene. For shale, their original porosity. Moreover, lithology, sandstone allowing a fluid dolomite siliceous rocks.
