| description | The invention provides a method for determining economic boundaries of oil reservoir parameters of all small layers of a multilayer combined oil recovery reservoir. The method for determining the economic boundaries of the oil reservoir parameters of all the small layers of the multilayer combined oil recovery reservoir comprises the steps that 1, characterization indexes of the oil reservoir parameters of all the small layers are calculated according to the set oil reservoir parameters of all the small layers; 2, according to the oil saturation of each small layer of the current oil reservoir, the oil saturation of each small layer from production to the payback period is calculated; 3, calculating the sum of the accumulated oil yields of all the small layers from production to the investment payback period; 4, calculating the economic limit accumulated oil production; and 5, determining the economic limit of each small-layer oil reservoir parameter of the multi-layer commingled oil reservoir.
