Description
technical field [0001] The application belongs to the technical field of petroleum exploitation, and in particular relates to an analysis method and device for factors affecting oxidation of heavy oil. Background technique [0002] The oxidation of heavy oil is mainly to heat up the heavy oil through different heating methods and heating media, so as to improve its fluidity. At present, when using conventional test methods to determine the influencing factors of heavy oil oxidation, the experimental workload is large, and it is impossible to analyze the influencing factors of heavy oil oxidation, which has little guiding effect on later production. [0003] For example, in the paper "Experiment and Model Research on Low-temperature Oxidation of Heavy Oil" (Applied Chemical Industry, 2013, 42(2): 259-263), the influence of temperature and pressure on low-temperature oxidation of heavy oil was studied. Experiments show that heavy oil begins to undergo low-temperature oxidatio...
