Method for determining fracturing process parameters of oil and gas reservoir

The invention relates to a method for determining fracturing process parameters of an oil and gas reservoir, and belongs to the technical field of petroleum and natural gas reservoir transformation. According to the method, the historical fracturing data is acquired, the post-fracturing productivity prediction model is established according to the historical fracturing data, and the well layer closest to the inherent parameters of the target well layer is selected from the historical fracturing data to serve as the similar well layer; and determining the fracturing parameters of the target well layer by using the fracturing data of the similar well layer, the inherent parameters of the target well layer and the after-fracturing productivity prediction model. According to the method, historical fracturing data are fully considered, the problem that an independent fracturing design cannot learn and refer to successful cases existing in history is solved, the fracturing effect is improved, and the yield increasi
