Abstract: A simulation study of gas reservoir performance with bottom water is carried out by employing the coning model. By means of the sensitlvity analysis production ratio,net pay thickness of gas一bearing formation,aquifer volume, vertical permeability to horizontal permeability ratio,horizontal permeability and gas well penetration are studied. Effects of these parameters on prcduction result of the gas reservoir are obtained, which provides a scientific basis for valid development of the gas reservoir with bottom water.

Key words: gas reservoir with bottom water, simulation study, sensitivity analysis, coning model
