Gas well productivity obtaining method, device, equipment, storage medium and program product

The invention provides a gas well productivity obtaining method and device, equipment, a storage medium and a program product. The method comprises the steps that an obtaining instruction and well testing data of a target gas well are received; the initial productivity equation of the target gas well is transformed, a multiple linear regression equation is obtained, the initial productivity equation is an equation established by adopting pseudo-pressure productivity well testing on the target gas well, and the productivity coefficient of the initial productivity equation is a coefficient to be solved in the multiple linear regression equation; solving a value of a coefficient to be solved in the multiple linear regression equation by utilizing multiple groups of measurement data in well testing data of the target gas well, and substituting the solved value of the coefficient back to the initial productivity equation to obtain a productivity equation of the target gas well; and calculating and outputting the p
