文摘

Experimental work was performed to evaluate the IOR performance of gas flooding in nano-permeability shale plugs.

Numerical simulation models were used to history match the experimental data and to analyze the recovery process.

Gas injection pressure is an important factor of the flooding process.

The effect of gas injection pressure on breakthrough time, recovery history, and ultimate recovery factor is discussed.
