The invention discloses a dolomite reservoir prediction method and system based on well and seismic combination, and a storage medium. The method comprises the following steps: acquiring logging dataof a testing area; carrying out sensitive curve analysis on logging data of a drilling area, obtaining a dolomite index characteristic curve, and distinguishing dolomite and limestone according to response range difference of the dolomite index characteristic curve; carrying out artificial intelligence deep learning on the dolomite index characteristic curve of the drilling area to obtain a dolomite index characteristic curve of a virtual drilling area; and by taking the dolomite index characteristic curves of the drilling area and the virtual drilling area as constraint conditions, carrying out inversion by adopting post-stack seismic data to obtain distribution and development conditions of a dolomite reservoir in the testing area. According to the method, the dolomite and the limestoneare effectively distinguished through the dolomite index characteristic curve; through the artificial intelligence deep learning and by combining the post-stack seismic data, the distribution and development conditions of the dolomite reservoir in the testing area can be accurately predicted; and the effective prediction method is provided for exploration work of a few-well area.
