Beschreibung
Zusammenfassung:	The invention discloses a gas-water two-phase flow yield prediction method considering stress sensitivity, and the method comprises the following steps: S1, building a productivity equation considering stress sensitivity, S2, solving unknown numbers in the productivity equation, and obtaining the optimal value of the unknown numbers; the method specifically comprises the following sub-steps: S21, assuming an initial value of the unknown number; s22, the theoretical value of the daily output of the gas well is determined according to the productivity equation under the initial value condition; s23, comparing the theoretical value of the daily output of the gas well with the actual production data of the daily output of the gas well, and calculating the deviation between the theoretical value and the actual production data; if the deviation is greater than a deviation threshold value, repeating the steps S21-S23; if the deviation is smaller than or equal to the deviation threshold value, the corresponding initi
