%X The data survey was collected in Beijing from 2019 to 2020. The data resources include shallow geological hazard prediction data and actual logging data from three wells. Based on the research results, combined with the acoustic logging data of Sakhalin North Vinny 3 well (shallow gas), LS18-2-1 well (shallow water flow), and MK1 well (natural gas hydrate), the shallow gas pressure, shallow water flow pressure, and natural gas hydrate saturation were calculated and compared with the shut in pressure measurement data and natural gas hydrate coring data to verify that the prediction accuracy reached 80%. Data collection, comprehensive logging instrument model ECLIPS-5700, compensating acoustic measurement model 1609XA, maximum outer diameter 3-3/8in, measurement range 128 μ s/m-640 μ s/m, error ± 7 μ s/m.
