Experimental study on supercritical CO2 huff-n-puff process for mid-deep heavy oil reservoirs by Silangluojia , ZHOU Xiang, SUN Xinge, ZHAO Yulong, ZHANG Liehui, WU Yang, PU Hongbin, JIANG Qi

“…Experiments were conducted to investigate CO2 diffusion in crude oil, supercritical CO2 extraction of heavy oil, and the high-temperature and high-pressure long-core huff-n-puff tests, aiming to elucidate the mechanisms of CO2 injection in heavy oil reservoirs and the efficient CO2 huff-n-puff development mechanisms. The experimental results indicated that: (1) the diffusion coefficient of CO2 in heavy oil exhibited a positive correlation with both injection temperature and pressure, with pressure demonstrating a greater influence on the diffusion coefficient than temperature. (2) With increasing extraction cycles, the mass fraction of medium-light components (C6 to C12) decreased significantly, while the mass fraction of medium-heavy components (C14+) gradually increased, particularly evident within the first three extraction cycles. (3) For heavy oil reservoirs, the recovery rate under depletion development was only 7.01%, while CO2 huff-n-puff development proved effective in enhancing recovery, achieving a cumulative recovery rate of 36.94% and an oil replacement ratio of 0.59 t/t (oil production per ton of CO2 injected). (4) Through huff-n-puff experiments, the optimal soaking time was determined to be 1-2 hours, and the optimal pressure depletion rate was 50 kPa/min. …”
