Establishing method of gas well reasonable production allocation chart in early stage of strong heterogeneous gas reservoir development

The invention discloses a method for establishing a gas well reasonable production allocation chart in the early stage of strong heterogeneous gas reservoir development. The method comprises the following steps that 1, the high-quality reservoir development scales of a plurality of gas wells are calculated respectively; 2, the production allocation systems of different stable production years of the multiple gas wells are determined through a three-factor coupling method; and 3, according to the results of the step 1 and the step 2, establishing a reasonable production allocation chart of the early-stage gas well in the development of the strong heterogeneity carbonate rock gas reservoir. According to the method, the development scale of the high-quality reservoir is calculated by using the plane distribution radius and the longitudinal vertical thickness of the high-quality reservoir clearly determined by the seismic data volume and the well logging interpretation result, the corresponding chart is establish
