Abstract: The present disclosure provides a method for determining effective storage capacity of a gas storage reconstructed from a water-flooded volatile oil reservoir. The method includes: determining an oil reservoir water flooding recovery ratio; determining crude oil production extracted only due to a water flooding effect in an oil reservoir development process; determining an oil-bearing pore volume of a flooded zone of a reservoir influenced due to the water flooding effect and an oil-bearing pore volume of a pure oil zone of a reservoir not influenced due to the water flooding effect corresponding to its original state before an oil reservoir is put into development when the gas storage is reconstructed from the oil reservoir; determining an effective pore volume for gas storage; and computing the effective storage capacity of the gas storage reconstructed from the water-flooded volatile oil reservoir.
