The present application belongs to the field of oil and gas development and energy utilization, and relates to a shale oil and gas stimulation method using chemical energy for in-situ deep stimulation of reservoirs. The method aims to solve the problems of single well production being lower than the economic development threshold, low recovery rate, obvious production capacity decline and waste of resources. The present application comprises the following steps: perforating a horizontal well, injecting high-viscosity slick water and large-diameter proppants to form a primary main seepage channel, and then injecting liquid explosives; pushing the explosives to the primary main seepage channel by low-viscosity slick water to form a secondary seepage channel; and then injecting low-viscosity slick water and small-diameter proppants for support. Finally, the well is put into production after well killing and liquid discharge. The present application combines the advantages of static hydraulic load and chemical energy high-energy fracturing to realize the construction of multi-stage seepage channels, significantly improving the efficiency and quality of deep shale oil and gas resource development. Through the detonation method, water resources can be significantly saved.
