注蒸汽开发后油藏火驱原位制氢可行性
Feasibility of In-Situ Hydrogen Production During Fire Flooding in Reservoirs after Steam Injection Development
摘要
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 produc-tion 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.关键词
