Summary:A series of kinetics and combustion tube experiments were conducted to investigate the combustion characteristics and performance of in situ combustion (ISC) process for offshore heavy oils. Then, simulation studies were carried out to evaluate the performance of the ISC process in a typical offshore heavy oil reservoir. The results showed that higher heating rates resulted in a shift in the thermogravimetry curves and an increase in the weight loss rate. The oil recovery, oxygen utilization, and air/oil ratio of the combustion experiment are 95.1%, 97.27%, and 547.78 m 3 /t, respectively. This research will provide technical support for ISC applications in offshore heavy oil reservoirs
