【摘要】：超稠油開(kāi)發(fā)難點(diǎn)在于地下大幅度降低原油黏度,催化氧化改質(zhì)具有應(yīng)用潛力,但需要找到兼具活性與注入能力的催化劑,研究其反應(yīng)機(jī)理.通過(guò)微乳液法制備并表征了納米過(guò)渡金屬催化劑,用以輔助超稠油注空氣氧化改質(zhì)吞吐的對(duì)比實(shí)驗(yàn),結(jié)果表明氧化改質(zhì)能夠大幅度降低超稠油黏度,降黏率最高達(dá)99.86%,納米金屬催化下的改質(zhì)溫度降至240℃,改質(zhì)速率與產(chǎn)油效果均顯著優(yōu)于微米級(jí)粉末催化劑,實(shí)驗(yàn)推測(cè)了氧化改質(zhì)反應(yīng)在不同溫度下的四步機(jī)理,包括雜元素?cái)噫�、初步氧化、深度氧化與高溫脫羧.與加氫還原改質(zhì)超稠油相比,納米催化氧化改質(zhì)更具有降黏效果好、成本低、易實(shí)施的特點(diǎn),具有一定的工業(yè)應(yīng)用潛力.
[Abstract]:The difficulty in the development of super heavy oil is to reduce the viscosity of crude oil by a large margin and to improve the quality of oil by catalytic oxidation. However, it is necessary to find a catalyst with both activity and injection ability and study its reaction mechanism. Nano-transition metal catalysts were prepared and characterized by microemulsion method, which were used to assist the comparison experiment of air injection oxidation and puff. The results showed that the oxidation modification could greatly reduce the viscosity of super heavy oil. The highest viscosity reduction rate was 99.86, and the modification temperature was reduced to 240 鈩，
