The invention relates to the technical field of petroleum and natural gas, in particular to a plunger gas lift process well selection method which comprises the following steps: S1, checking historical production data of a target well, and judging the gas production potential of the target well as a condition a; s2, checking historical production data of the target well, and judging the difference value of the gas production rate of the target well when the liquid drainage gas production measure exists and the gas production rate of the target well when the liquid drainage gas production measure does not exist, and taking the difference value as a condition b; s3, the instantaneous gas production rate after the target well is restarted after pressure storage is judged to serve as a condition c; and S4, the condition a, the condition b and the condition c are integrated, if the target well has the gas production potential, the difference value is positive, and the instantaneous gas production rate meets the pl
