Abstract

In order to identify the effect of ultra-fine transition metal catalyst on the in-situ combustion of heavy oil

thermal analysis and isoconversional method were used to evaluate the burning oxidation kinetics of three ultra-fine transition metal particles—NiO

α·Fe

and Co

. And then

one-dimensional in-situ combustion experiment was carried out by the optimized catalyst. The experimental results showed that

in the presence of Co

the activation energy of heavy oil decreased the m

ost

up to 41.7 %. Meanwhile

had higher catalytic activity

that made it suitable for in-situ combustion experiment. Compared to conventional in-situ combustion

high temperature oxidation reaction of crude oil was enhanced under the catalytic condition of Co

. The oxygen utilization ratio increased by 6.79 %

the combustion time shortened by 11.8 %

the average temperature of the leading edge of combustion increased by 20 ℃

the maximum temperature difference of the leading edge of combustion reduced by 4 ℃

the combustion was more stable

the advance speed of the leading edge increased by 0.042 cm/min

the final oil displacement efficiency increased by 5.7 %

and the viscosity reduction rate of the produced oil increased by 7.2 %. The research results have important guiding significance for expanding the application of heavy oil recovery by in-situ combustion.
