Abstract: According to the current state of residue hydrocracking process and production of Refining & Chemical Complex of PetroChina Yumen Oilfield,this paper takes heavy oil balance, product upgrading, and other factors affecting refinery efficiency into account, puts forward three options suitable for heavyoil processing of the Complex and compares the options in terms of investment, efficiency, and upgrading potential. After an overall analysis, it is proved thatresidue hydrocracking process could not only solve the heavy oil balance problem and meet fuel upgrading demand, but also improve the processing flowand product structure of the Complex. As an important means of heavy oil processing, residue hydrocracking process not only occupies a strong advantage inenvironmental protection and efficiently, but also has certain practical significance to the development and transformation of the Complex in the future.

Key words: residue hydrocracking, heavy oil processing, cleaning, heavy oil balance
