Abstract 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 m3/t, respectively. This research will provide technical support for ISC applications in offshore heavy oil reservoirs

海上稠油油藏原位燃烧过程试验与模拟研究

摘要 为了研究海上稠油原位燃烧（ISC）工艺的燃烧特性和性能，进行了一系列动力学和燃烧管实验。然后，进行了模拟研究，以评估典型海上稠油油藏中 ISC 过程的性能。结果表明，较高的加热速率导致热重曲线的移动和失重速率的增加。燃烧实验的油回收率、氧气利用率和空油比分别为95.1%、97.27%和547.78 m3/t。该研究将为海上稠油油藏ISC应用提供技术支持
