Effects of gas injection combined with wettability alteration on boundary water inrush

The inrush of boundary water can aggravate water blockage during the middle-late-aquifer influx period, which is frequently encountered in various gas reservoirs. This study attempts to use gas injection combined with wettability alteration to address this problem. Gas injection experiments were con...

520			\|a The inrush of boundary water can aggravate water blockage during the middle-late-aquifer influx period, which is frequently encountered in various gas reservoirs. This study attempts to use gas injection combined with wettability alteration to address this problem. Gas injection experiments were conducted using a visual flow cell with and without wettability alteration, considering both continuous and temporary gas injection. Intercepting the boundary water, as a core characteristic of gas injection, was investigated. The results showed that the relative hydraulic conductivity was reduced to approximately 0.1 by combining continuous gas injection with wettability alteration to gas-wet, indicating that this method can potentially be applied in gas reservoirs with large hydraulic gradients. In addition, the flow path of the gas is smoother and shorter in the porous medium with wettability alteration, and the desaturated zone presents a conical development at different gas flow rates. After temporary gas injection in a porous medium with wettability alteration, the relative hydraulic conductivity can be reduced to less than 0.4 due to the internal trapped gas. Hence, temporary gas injection combined with wettability alteration can be applied when the hydraulic gradient is small. It is hoped that these results can provide new insights for addressing the boundary water inrush.

This study attempts to use gas injection combined with wettability alteration to address this problem. Gas injection experiments were conducted using a visual flow cell with and without wettability alteration, considering both continuous and temporary gas injection. Intercepting the boundary water, as a core characteristic of gas injection, was investigated. The results showed that the relative hydraulic conductivity was reduced to approximately 0.1 by combining continuous gas injection with wettability alteration to gas-wet, indicating that this method can potentially be applied in gas reservoirs with large hydraulic gradients. In addition, the flow path of the gas is smoother and shorter in the porous medium with wettability alteration, and the desaturated zone presents a conical development at different gas flow rates. After temporary gas injection in a porous medium with wettability alteration, the relative hydraulic conductivity can be reduced to less than 0.4 due to the internal trapped gas. Hence, temporary gas injection combined with wettability alteration can be applied when the hydraulic gradient is small. It is hoped that these results can provide new insights for addressing the boundary water inrush.

abstract	The inrush of boundary water can aggravate water blockage during the middle-late-aquifer influx period, which is frequently encountered in various gas reservoirs. This study attempts to use gas injection combined with wettability alteration to address this problem. Gas injection experiments were conducted using a visual flow cell with and without wettability alteration, considering both continuous and temporary gas injection. Intercepting the boundary water, as a core characteristic of gas injection, was investigated. The results showed that the relative hydraulic conductivity was reduced to approximately 0.1 by combining continuous gas injection with wettability alteration to gas-wet, indicating that this method can potentially be applied in gas reservoirs with large hydraulic gradients. In addition, the flow path of the gas is smoother and shorter in the porous medium with wettability alteration, and the desaturated zone presents a conical development at different gas flow rates. After temporary gas injection in a porous medium with wettability alteration, the relative hydraulic conductivity can be reduced to less than 0.4 due to the internal trapped gas. Hence, temporary gas injection combined with wettability alteration can be applied when the hydraulic gradient is small. It is hoped that these results can provide new insights for addressing the boundary water inrush.
