description The invention relates to the field of oil and gas field development, in particular to a condensate gas reservoir gas-oil ratio calculation method which comprises the following steps: S1, comparing bottom hole pressure Pws obtained by static ladder test with calculated bottom hole pressure P'ws obtained by assumed condensate gas phase relative density gamma 'G to obtain reasonable condensate gas phase relative density gamma G; and S2, calculating the gas-oil ratio Rgo by utilizing the reasonable condensate gas phase relative density gamma G. The method for calculating the gas-oil ratio of the condensate gas reservoir has a strict theoretical derivation basis, eliminates the influence of interference of human factors, defects of metering and separating devices and the like, is high in reliability, high in calculation speed and real and reliable in data, and can effectively guide production adjustment; various defects of determining the gas-oil ratio by adopting a ground metering mode at present can be solved, t
