摘要：

It is a promising CO2 sequestration technology to inject CO2 gas into seabed strata and depleted oil and gas reservoirs to form stable CO2 hydrate. In order to further explore this technology, the CO2 sequestration experiment simulation of natural wet sand at 3MPa and 5℃ was carried out by using hydrate method. The initial water saturation was set at 10%, 40% and 70%, respectively. The storage experiments of pure water and 3.5% (mass fraction) NaCl solution were carried out. The CO2 storage effect under three different intake directions (top intake, horizontal intake and bottom intake) was also explored with the reaction still system independently developed. The results show that the storage stock of the horizontal inlet is generally larger than that of the top inlet, while the storage stock of the bottom inlet is the smallest, and the storage speed of the horizontal inlet is the fastest. It is also found that the higher the initial water saturation, the higher the hydrate saturation, but the lower the hydrate conversion rate, the lower the solid state sequestration ratio. Compared with the pure water experiment, the presence of salt reduces the CO2 storage stock, and the proportion of solid storage is lower than that of the pure water experiment, but the storage speed is faster. The experiment provides a basis for the reasonable control of the water saturation, salinity and the appropriate intake direction in the actual engineering operation. © 2021, Chemical Industry Press Co., Ltd.
