This invention relates to a method for optimizing the tubing size of injection and production wells in a water-driven sandstone oil and gas reservoir, comprising the following steps: 1. Determine the coefficients A and B of the binomial production capacity equation for the gas well and establish the production capacity equation. 2. Analyze and determine the critical sand production pressure difference during gas production in the target gas reservoir's injection and production wells. 3. Establish a binomial function relationship between formation pressure and cumulative gas production. 4. Calculate the formation pressure during the peak winter gas production period of the target gas reservoir based on the established binomial function relationship. 5. Use nodal analysis to perform dynamic modeling and calculate the production capacity of different tubing sizes under different formation pressures and production pressure differences. 6. Based on the production capacity under peak formation pressure, use cross-plots to quantitatively optimize the tubing size with a production capacity increase of 10% and a critical sand production pressure difference of less than 3 MPa. This significantly reduces the blind selection of tubing and ensures the gas supply capacity and reliability of the gas reservoir during the critical peak-shaving period.
