Claim Text:
1. A integrated process for processing heavy oil, comprising at least the following processes, wherein: a heavy oil feedstock, which substantially does not comprise <350° C. atmospheric distillates, is used as feed and subjected to solvent deasphalting process in an extraction tower with an extraction solvent, a de-asphalted oil and a de-oiled asphalt phase including the extraction solvent are collected; the de-oiled asphalt phase including the extraction solvent is mixed with a dispersing solvent and then enters into a thermal cracking reactor to be subjected to a thermal cracking process, so as to obtain thermal cracking reaction product and coke, the thermal cracking reaction product is led out, gas, solvent, thermal cracking oil and 450° C.+ heavy gas oil are separated therefrom; the solvent separated from the thermal cracking product is recycled back to the solvent deasphalting process to be recycled, the 450° C.+ heavy gas oil is recycled back to the solvent deasphalting process to be used as mixed feed; upgraded oil is obtained through mixing the de-asphalted oil and the thermal cracking oil separated from the thermal cracking reaction product.
