The invention provides a method for modification and resource utilization of coal-oil coprocessing residues. According to the method, the coal-oil coprocessing residues are micronized and dispersed into micro particles with the diameter of 0.1-10mm through jetting; the micro particles, coal, water and a coal water slurry additive are subjected to roll milling, and coal water slurry is blended, wherein the micro particles are subjected to surface dipping modification in a water solution containing macromolecule surface modifiers; gasifying and coupling integrated utilization is performed to obtain synthesis gas and ash, the synthesis gas can be further converted into products such as methyl alcohol and olefin, the ash is buried or made into cement, and the coal-oil coprocessing residues are subjected to harmless treatment and resource utilization. The defects that due to high adhesiveness caused by high asphaltene content in the coal-oil coprocessing residues, when the water coal slurry is directly blended, th
