Low-permeability tight gas reservoir interlayer adjustment method based on commingling production control radius algorithm

The invention relates to the field of oil and gas field development, in particular to a low-permeability tight gas reservoir interlayer adjustment method based on a commingling production control radius algorithm. The technical problem that in the middle and later periods of exploitation of the low-permeability tight gas reservoir, the exploitation efficiency is low due to the fact that the utilization degree of interlayer reserves is unbalanced due to heterogeneity is solved; by establishing equivalent substance conservation equations of different commingled production models and combining gas reservoir production dynamic data, the commingled production layer control radius of different layers of the low-permeability tight gas reservoir can be accurately calculated, and meanwhile, the inter-layer adjustment principle is finally comprehensively determined by combining single production and commingled production average cumulative gas production amount EUR. The method is reliable in principle, simple to use, p
