Gravity flow water channel sand body detection method and device and readable storage medium

The invention discloses a gravity flow channel sand body detection method and device and a readable storage medium, and relates to the field of geological exploration. According to the gravity flow channel sand body detection method provided by the invention, the water channel data is acquired, the water channel data is corrected, the water channel data and the seismic data are subjected to well-seismic combination, the corresponding relation between the sandstone reservoir and the seismic reflection event is determined, and the seismic reflection structure feature types of the sand bodies in different sand shale combinations are firstly divided; and secondly, determining geological laws of distribution of different sedimentary microfacies sandstones in combination with a general sedimentary microfacies model of the gravitational flow channel sandstones, obtaining sandstone thicknesses according to the first pair of three-dimensional seismic body tracking in combination with a time-depth relationship, and cor
