The application provides a differentiated hole arrangement design method for increasing the number of fracture cracks in a heterogeneous reservoir, and belongs to the technical field of oil and gas exploitation. Reservoir quality parameters, rock mechanics parameters and ground stress parameters of a target well and fracture crack distribution of a neighboring well of the target well are obtained to design the number of fracture cracks / cluster number, position and shape of each cluster of cracks. A mathematical model of the fracture cracks is selected according to the ground stress parameters and the shape of each cluster of cracks to calculate the net pressure required by the shape of each cluster of cracks. A random algorithm is used to determine the displacement of each cluster of cracks and the number of perforation holes, and the friction of each cluster of crack holes is calculated. The bottom hole pressure of each cluster of cracks is calculated according to the net pressure of each cluster of cracks and the friction of each cluster of crack holes, and if the bottom hole pressure of each cluster of cracks is equal, the next step is performed. The ground pumping pressure is calculated by using a fluid mechanics method, and if the ground pumping pressure meets the set conditions, the design is completed. The method can reduce the downhole complex risks such as channeling, improve the fracturing construction efficiency and reservoir reconstruction effect, and reduce the construction cost.
