High-pressure gas shock vibration cementing system and vibration cementing method

The invention discloses a high-pressure gas shock vibration cementing system and a vibration cementing method, and belongs to the field of oil-gas well engineering. The vibration cementing system is characterized in that a casing is preinstalled in the center of a well wall, and an annular space is formed between the casing and the well wall; a rubber plug is put at an appropriate position in thecasing, and the upper end of the rubber plug is sealed with the inner wall of the casing through a sealing ring; cement paste in which high-temperature fusible aerated particles are uniformly added isprepared outside a well; the casing is lowered to a preset position in the oil-gas well, and the cement paste is injected into the casing; drilling fluid is injected after the rubber plug and the sealing ring are put into the casing; and pressure is applied to the rubber plug to make the cement paste reach a preset position of the annular space and a preset temperature, the cement paste is moved,the high-temperature fusib
