| description | The invention relates to a coal measure strata tight sandstone reservoir prediction method and device, a medium and equipment, and the method comprises the following steps: obtaining the parameters of a coal seam, sandstone, mudstone and limestone in a coal measure strata based on rock physical analysis; based on a seismic wave impedance inversion technology, depicting the distribution of the coal seam and the limestone, and stripping the coal seam and the limestone from a wave impedance inversion data body; obtaining a gamma data volume by using a seismic waveform indication inversion technology based on a gamma curve, and depicting sandstone and mudstone; sandstone distribution is engraved on the basis of stripping the coal seam and the limestone and depicting the sandstone and the mudstone, finally, the coal seam, the limestone and the mudstone are effectively stripped, and the range of the compact sandstone is obtained. According to the method, through deep rock physical analysis, a seismic wave impedance |
