Physical-process production and injection increasing effect evaluation simulated experiment method for oil-water well

The invention provides a physical-process production and injection increasing effect evaluation simulated experiment method for an oil-water well. By utilizing a natural outcrop core of a reservoir, an equal proportional simulated wellbore is designed and manufactured to simulate an actual physical-process production and injection increasing environment. A method for testing pressure at different distances of a shaft during operation of physical-process production and injection increasing measures is designed to analyze an operating distance and an attenuation law of an impact wave; a simulated shaft core taking method is designed to analyze the degree of change of permeability of a sample at different distances of the shaft, and to research a relationship between parameters of the impact wave and improvement of the permeation capacity of the reservoir; the type of formation fracturing caused by a strong impact wave and the degree of injury to a casing pipe and a cement sheath are determined. The operating me
