%X The data were collected in Beijing from 2019 to 2020. Data resources include shallow geological disaster prediction data and actual logging data of three wells. According to the research results, the shallow gas pressure, shallow water flow pressure and gas hydrate saturation are calculated by combining with the acoustic logging data of well sanhalin North vini 3 (shallow gas), well ls18-2-1 (shallow water flow) and well MK1 (gas hydrate). Compared with shut in pressure measurement data and gas hydrate coring data, the prediction accuracy is 80%. Data acquisition: eclips-5700, 1609xa, 3-3 / 8in, 128 μ s/m-640 μ S / m, error ± seven μ s/m。
