This invention discloses a combined process for restoring reservoir drainage and gas production channels using high-pressure drive and chemical dissolution, relating to the field of efficient oilfield exploitation technology. The process includes: S1, conducting production profile testing and sampling analysis of blockages in the target gas well to determine the type, distribution location, and reservoir physical parameters of the blockages, and preparing a corresponding chemical dissolving agent based on the analysis results. This invention couples the mechanical fracture-creating effect of high-pressure pulsed fluid with the cavitation effect and vibrational mass transfer effect of ultrasound. Based on the initial dissolution of blockages by the chemical dissolving agent, the stress waves generated by the high-pressure pulse expand the reservoir microfractures. Simultaneously, the collapse of microbubbles generated by ultrasound enhances the dissolution reaction rate, and the vibration promotes the dissolving agent's penetration into the micropores, achieving a synergistic effect of chemical dissolution and physical displacement, thoroughly removing blockages from the pore throats, and avoiding secondary precipitation of dissolution products.
