Abstract: The coal-formed oil often gives rise to a good deal of controversy. Is the crude oil of Austrilian Gippsland basin coal-formed oil? Is the crude oil of Turpan-Hami basin is coal-formed oil? Is the crude oil comes from some coal-bearing basins of China is coal-formed? Is the pyrolysis assay simulating experiment valid and effective? All those questions have to be discussed further. The current study shows that the crude oil of coal-bearing basin could not have been generated from coal-bearing rock, meanwhile, it is not likely to generate from mudstone in coal-bearing systems. The possible oil-generating pattern will be the hydrogenization and liquidazation reaction occurring between the deep buried hydrogen and organics, or the hydrocarbons is generated from the H2,CO2,CO existing in low-velocity and high conductivity strata of the middle earth crust subjected to the Feito synthesis process.

Key words: coal-formed oil, Jurassic, inorganic origin, Feito synthesis
