Experimental study on supercritical CO2 huff-n-puff process for mid-deep heavy oil reservoirs
Published 2025-08-01“…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. …”
