Abstract: The relative stability of crude oil is important to ensure safe operation and profit improvement of refineries. By combining the crude oil spectral database, crude oil evaluation database, crude oil rapid assay and advanced calculation method,SINOPEC Research Institute of Petroleum Processing has combined several crude oils in a certain proportion to obtain a formulated crude oil that are very close to the properties of target crude oil, thus forming the crude formulation technology. Refinery can choose the appropriate crude formula according to the principles of crude oil price, availability of crude oil, processing performance of mixed crude oil and optimization target of refinery. Laboratory evaluation shows that the actual analysis results are similar to those calculated by the technology. If this technology can be popularized and used, it can play an important role in improving refinery profit.

Key words: formulated crude, refinery optimization, crude oil blending, crude oil rapid assay
