The vibration wave generator is provided with an upper connector and a one-way valve, the two ends of a center pipe are connected with the upper connector and the one-way valve respectively, and a jetting body and a resonance body are installed outside the portion, between the upper connector and the one-way valve, of the center pipe. A liquid flow hole is formed in the pipe body of the central pipe corresponding to the jetting cavity of the jetting body, and a vibration gap is formed between the resonance body and the central pipe. The gas-water mixing device is simple in structure and convenient to construct, can be used in a well by connecting an oil pipe column with the upper connector, can realize gas-water mixing at a wellhead, and can realize underground low-frequency large-amplitude vibration waves through gaps between the jetting body and the central pipe and gaps between the resonance body and the central pipe and a cavitation structure formed by the jetting body and the resonance body.
