摘要: 针对注蒸汽开发后油藏中火驱原位制氢技术的可行性问题,通过燃烧管实验,开展了含水饱和度对稠油原位制氢效果的影响研究。结果表明:水的存在增强了对流传热效应,为碳氢化合物中C—C和C—H的断裂提供了高温环境;并促进了稠油水热裂解、焦炭气化、水汽变换等可逆反应向制氢方向移动,提高了制氢效果。在含水饱和度为24.58%时,温度最高达715.1 ℃,氢气体积分数最高为1.03%。研究结果验证了注蒸汽开发后稠油油藏火驱原位制氢的可行性,该研究对提高稠油火驱原位制氢效果具有重要参考价值。

Abstract: A study on the influence of water saturation on the in-situ hydrogen production effect from heavy oil was carried out through combustion tube experiments to study the feasibility of technology on in-situ hydrogen production during fire flooding in reservoirs after steam injection development. The results show that the presence of water enhances the convective heat transfer effect and provides a high-temperature environment for the fracture of C-C and C-H in hydrocarbons and promotes the reversible reactions such as hydrothermal cracking, coke gasification, and water-steam conversion of heavy oil to move toward hydrogen production, which improves the in-situ hydrogen production effect. The temperature is 715.1 ℃, and the hydrogen volume fraction is up to 1.03% when the water saturation reaches 24.58%. The results verified the feasibility of in-situ hydrogen production from heavy oil during fire flooding in heavy oil reservoirs after steam injection development, and the study has significant reference value for improving the in-situ hydrogen production effect from heavy oil during fire flooding.

Key words: heavy oil, hydrogen energy, fire flooding, in-situ hydrogen production, water saturation
